最完整的！WinForm使用ICSharpCode.TextEditor控件实现自定义高亮显示

1.此案例以WinForm为例，首先下载个ICSharpCode.TextEditor.dll文件（官方版本不报错，下载地址：/download/king_miQ/15709167）。

2.将下载的ICSharpCode.TextEditor.dll文件拖拽至工具栏中，注意要打开文件所在位置，拖拽源文件此时才会在工具栏生成一个控件。

3.再将工具栏中的控件拖拽至窗体中，就会有如下文本域。

4.双击文本，此时就会生成加载事件的方法，路径指向文件配置路径，可直接复制如下代码，注意path的路径指向xshd文件

private void textEditorControl1_Load(object sender, EventArgs e){textEditorControl1.Encoding = System.Text.Encoding.UTF8;textEditorControl1.Font = new Font("Hack", 12);//自定义代码高亮string path = AppDomain.CurrentDomain.BaseDirectory + "../..//HighLighting";//指向自定义的文件FileSyntaxModeProvider fsmp;if (Directory.Exists(path)){fsmp = new FileSyntaxModeProvider(path);HighlightingManager.Manager.AddSyntaxModeFileProvider(fsmp);textEditorControl1.SetHighlighting("JackC#");}}}

5.新建一个文件夹和一个后缀为xshd的文件，文件的具体配置如下。

6.最终效果，因为我们此时定义的是Blue(蓝色)并在底下定义了Abs关键字，所以显示蓝色。

效果如下。
