// 添加引用 parameters.ReferencedAssemblies.Add(System.dll); parameters.ReferencedAssemblies.Add(System.Windows.Forms.dll); parameters.ReferencedAssemblies.Add(System.Drawing.dll); if (references ! null) { foreach (string reference in references) { parameters.ReferencedAssemblies.Add(reference); } } // 执行编译 CompilerResults compilerResults provider.CompileAssemblyFromSource(parameters, code); if (compilerResults.Errors.HasErrors) { result.Success false; result.Errors compilerResults.Errors.CastCompilerError() .Select(e new CompileError { Line e.Line, Column e.Column, ErrorNumber e.ErrorNumber, ErrorText e.ErrorText }).ToArray(); } else { result.Success true; result.CompiledAssembly compilerResults.CompiledAssembly; } } catch (Exception ex) { result.Success false; result.Errors new[] { new CompileError { ErrorText $编译异常: {ex.Message} } }; } return result; } } // 编译结果类 public class CompileResult { public bool Success { get; set; } public Assembly CompiledAssembly { get; set; } public CompileError[] Errors { get; set; } } // 编译错误类 public class CompileError { public int Line { get; set; } public int Column { get; set; } public string ErrorNumber { get; set; } public string ErrorText { get; set; } }6.2 实时错误检查在代码编辑时实时检查语法错误public class RealTimeErrorChecker { private readonly DynamicCompiler _compiler; private readonly RichTextBox _editor; private Timer _checkTimer; public RealTimeErrorChecker(RichTextBox editor) { _editor editor; _compiler new DynamicCompiler(); SetupCheckTimer(); } private void SetupCheckTimer() { _checkTimer new Timer { Interval 1000 }; // 1秒延迟 _checkTimer.Tick async (s, e) await CheckErrorsAsync(); _editor.TextChanged (s, e) _checkTimer.Stop(); _editor.TextChanged (s, e) _checkTimer.Start(); } private async Task CheckErrorsAsync() { _checkTimer.Stop(); string code _editor.Text; if (string.IsNullOrWhiteSpace(code)) return; await Task.Run(() { // 包装代码为完整类进行编译检查 string wrappedCode WrapCodeForCompilation(code); CompileResult result _compiler.Compile(wrappedCode, null); // 在主线程更新UI _editor.Invoke(new Action(() DisplayErrors(result.Errors))); }); } private string WrapCodeForCompilation(string code) { return $ using System; using System.Windows.Forms; using System.Drawing; namespace TempCompilation {{ public class TempClass {{ {code} }} }}; } private void DisplayErrors(CompileError[] errors) { // 清除之前的错误标记 _editor.SelectAll(); _editor.SelectionBackColor Color.White; foreach (var error in errors) { if (error.Line 0) { int startIndex GetCharIndexFromLine(error.Line - 4); // 减去包装代码的行数 if (startIndex 0 startIndex _editor.TextLength) { // 找到行尾 int lineEnd _editor.Text.IndexOf(Environment.NewLine, startIndex); if (lineEnd -1) lineEnd _editor.TextLength; _editor.Select(startIndex, lineEnd - startIndex); _editor.SelectionBackColor Color.LightPink; } } } _editor.Select(0, 0); // 取消选择 } private int GetCharIndexFromLine(int lineNumber) { int currentLine 0; int index 0; while (currentLine lineNumber index _editor.TextLength) { if (_editor.Text[index] \n) { currentLine; } index; } return index _editor.TextLength ? index : -1; } }7. 可视化设计界面实现实现类似Visual Studio的拖拽设计功能。7.1 设计画布和控件工具箱public class DesignCanvas : Panel { private Control _selectedControl; private Point _dragStartPoint; private bool _isDragging; public event EventHandler SelectionChanged; public Control SelectedControl { get _selectedControl; set { if (_selectedControl ! value) { // 清除之前的选择样式 if (_selectedControl ! null) { _selectedControl.BorderStyle BorderStyle.None; } _selectedControl value; // 设置新选择的样式 if (_selectedControl ! null) { _selectedControl.BorderStyle BorderStyle.FixedSingle; } SelectionChanged?.Invoke(this, EventArgs.Empty); } } } public DesignCanvas() { this.BackColor Color.White; this.BorderStyle BorderStyle.FixedSingle; this.AllowDrop true; SetupEventHandlers(); } private void SetupEventHandlers() { this.MouseDown OnMouseDown; this.MouseMove OnMouseMove; this.MouseUp OnMouseUp;

_dragStartPoint e.Location; } } private void OnMouseMove(object sender, MouseEventArgs e) { if (_isDragging SelectedControl ! null) { int deltaX e.X - _dragStartPoint.X; int deltaY e.Y - _dragStartPoint.Y; SelectedControl.Left deltaX; SelectedControl.Top deltaY; _dragStartPoint e.Location; } } private void OnMouseUp(object sender, MouseEventArgs e) { _isDragging false; } private void OnDragEnter(object sender, DragEventArgs e) { if (e.Data.GetDataPresent(ControlType)) { e.Effect DragDropEffects.Copy; } } private void OnDragDrop(object sender, DragEventArgs e) { if (e.Data.GetDataPresent(ControlType)) { string controlType e.Data.GetData(ControlType).ToString(); CreateControlAtLocation(controlType, this.PointToClient(new Point(e.X, e.Y))); } } private void CreateControlAtLocation(string controlType, Point location) { Control newControl controlType switch { Button new Button { Text Button, Size new Size(75, 23) }, TextBox new TextBox { Text , Size new Size(100, 20) }, Label new Label { Text Label, AutoSize true }, CheckBox new CheckBox { Text CheckBox, AutoSize true }, _ new Panel { Text Control, Size new Size(100, 50) } }; newControl.Location location; this.Controls.Add(newControl); SelectedControl newControl; } } // 控件工具箱 public class ControlToolbox : FlowLayoutPanel { public ControlToolbox() { this.BackColor SystemColors.Control; this.BorderStyle BorderStyle.FixedSingle; this.Width 150; this.AutoScroll true; InitializeToolboxItems(); } private void InitializeToolboxItems() { AddToolboxItem(Button, 按钮); AddToolboxItem(TextBox, 文本框); AddToolboxItem(Label, 标签); AddToolboxItem(CheckBox, 复选框); AddToolboxItem(Panel, 面板); } private void AddToolboxItem(string controlType, string displayText) { var item new Label { Text displayText, BorderStyle BorderStyle.FixedSingle, BackColor Color.White, Margin new Padding(2), Padding new Padding(5), AutoSize true, Cursor Cursors.Hand }; item.MouseDown (s, e) { item.DoDragDrop(controlType, DragDropEffects.Copy); }; this.Controls.Add(item); } }7.2 属性面板实现public class ControlPropertyGrid : PropertyGrid { private Control _selectedControl; public Control SelectedControl { get _selectedControl; set { _selectedControl value; if (_selectedControl ! null) { // 创建可编辑的属性包装器 var wrapper new ControlPropertyWrapper(_selectedControl); this.SelectedObject wrapper; } else { this.SelectedObject null; } } } } // 控件属性包装器提供设计时属性编辑 public class ControlPropertyWrapper { private readonly Control _control; public ControlPropertyWrapper(Control control) { _control control; } [Category(外观)] [Description(控件上显示的文本)] public string Text { get _control.Text; set _control.Text value; } [Category(布局)] [Description(控件的位置)] public Point Location { get _control.Location; set _control.Location value; } [Category(布局)] [Description(控件的大小)] public Size Size { get _control.Size; set _control.Size value; } [Category(外观)] [Description(控件的前景色)] public Color ForeColor { get _control.ForeColor; set _control.ForeColor value; } [Category(外观)] [Description(控件的背景色)] public Color BackColor { get _control.BackColor; set _control.BackColor value; } [Category(行为)] [Description(控件是否可见)] public bool Visible { get _control.Visible; set _control.Visible value; } [Category(行为)] [Description(控件是否启用)] public bool Enabled { get _control.Enabled; set _control.Enabled value; } }8. 主界面集成与功能整合将所有组件整合到主界面中创建完整的IDE体验。8.1 主窗体设计public partial class MainIDEForm : Form { private CodeEditorControl _codeEditor; private DesignCanvas _designCanvas; private ControlToolbox _toolbox; private ControlPropertyGrid _propertyGrid; private TabControl _mainTabControl; private DynamicCompiler _compiler; public MainIDEForm() { InitializeComponent(); SetupMainInterface(); SetupEventHandlers(); } private void SetupMainInterface() { this.Text C# Mini IDE; this.Size new Size(1200, 800); this.StartPosition FormStartPosition.CenterScreen; // 创建主布局 var mainSplit new SplitContainer { Dock DockStyle.Fill, Orientation Orientation.Horizontal };

} else { ShowCompileErrors(result.Errors); } } private void ShowCompileErrors(CompileError[] errors) { var errorText new StringBuilder(编译错误:\n); foreach (var error in errors) { errorText.AppendLine($行 {error.Line}: {error.ErrorText}); } MessageBox.Show(errorText.ToString(), 编译错误, MessageBoxButtons.OK, MessageBoxIcon.Error); } }8.2 代码编辑器控件封装public class CodeEditorControl : UserControl { private RichTextBox _textBox; private CSharpSyntaxHighlighter _highlighter; private RealTimeErrorChecker _errorChecker; public CodeEditorControl() { InitializeComponent(); SetupEditor(); } private void InitializeComponent() { _textBox new RichTextBox { Dock DockStyle.Fill, Font new Font(Consolas, 10), AcceptsTab true }; this.Controls.Add(_textBox); } private void SetupEditor() { _highlighter new CSharpSyntaxHighlighter(_textBox); _errorChecker new RealTimeErrorChecker(_textBox); // 设置默认代码模板 _textBox.Text using System;

}9. 高级功能扩展基础IDE完成后可以添加一些高级功能提升实用性。9.1 项目文件管理public class ProjectManager { private string _projectPath; private readonly Liststring _sourceFiles; public ProjectManager() { _sourceFiles new Liststring(); } public void CreateNewProject(string projectName, string directoryPath) { _projectPath Path.Combine(directoryPath, projectName); if (!Directory.Exists(_projectPath)) { Directory.CreateDirectory(_projectPath); } // 创建项目文件 string projectFile Path.Combine(_projectPath, ${projectName}.csproj); CreateProjectFile(projectFile, projectName); // 创建主程序文件 string mainFile Path.Combine(_projectPath, Program.cs); CreateMainProgramFile(mainFile, projectName); _sourceFiles.Add(mainFile); } private void CreateProjectFile(string filePath, string projectName) { string content $?xml version1.0 encodingutf-8?
