asp.net实现Ｃ＃代码加亮显示

从别人那里照来的,还没试过

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(" \r\n");
foreach(string sourceLine in sr)

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

textBuffer.Write(" ");

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

textBuffer.Write(" \r\n");
foreach(string sourceLine in sr)

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

textBuffer.Write(" ");

else if(codeType=="VB")

textBuffer.Write(" \r\n");
foreach(string sourceLine in sr)

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

textBuffer.Write(" ");
