asp.net实现C#代码加亮显示

以下是代码片段：

StringWriter textBuffer = new StringWriter();

Match match= Regex.Match(HTMLStr,@"\",RegexOptions.IgnoreCase | RegexOptions.Compiled);

if(match==null)

{

Response.Write(HTMLStr);

return;

}

string codeType = match.Groups["codeType"].Value;

string content = match.Groups["codeContent"].Value;

if(codeType==String.Empty || content==String.Empty)

{

Response.Write(HTMLStr);

return;

}

// MessageBox.Show(codeType);

// MessageBox.Show(content);

string[] sr = content.Split(Convert.ToChar("\n"));

if(codeType=="C#")

{

textBuffer.Write("<Csharp>\r\n");

foreach(string sourceLine in sr)
{

textBuffer.Write(FixCSLine(sourceLine)) ;

textBuffer.Write("\r\n");

}

textBuffer.Write("</Csharp>");

}

else if(codeType=="JScript.Net")

{

textBuffer.Write("<JScript.Net>\r\n");

foreach(string sourceLine in sr)

{

textBuffer.Write(FixJSLine(sourceLine)) ;

textBuffer.Write("\r\n");

}

textBuffer.Write("</JScript.Net>");

}

else if(codeType=="VB")

{

textBuffer.Write("<VB>\r\n");

foreach(string sourceLine in sr)

{

textBuffer.Write(FixVBLine(sourceLine)) ;

textBuffer.Write("\r\n");

}

textBuffer.Write("</VB>");

}
