ActiproSoftware.Shared.Net20.dll CodeHighlighterTest.dll

三個dll的引用

3、將Languages 和 image 文件夾 拷貝到程序目錄中

<pre >
<CH:CodeHighlighter runat="server" OutliningEnabled="true" ID="CssCodeHighlighter"
LineNumberMarginVisible="true">
</CH:CodeHighlighter></pre>

this.CssCodeHighlighter.LanguageKey = ds.Tables[0].Rows[0]["codetype"].ToString().Trim();
this.CssCodeHighlighter.Text = ds.Tables[0].Rows[0]["Code"].ToString().Trim();
