C#源码匹配：

CSharpStringRegex = new Regex(@""".*?""|'.+?'", RegexOptions.Compiled);
CSharpCommentRegex1 = new Regex(@"//.*$", RegexOptions.Multiline | RegexOptions.Compiled);
CSharpCommentRegex2 = new Regex(@"(/\*.*?\*/)|(/\*.*)", RegexOptions.Singleline | RegexOptions.Compiled);
CSharpCommentRegex3 = new Regex(@"(/\*.*?\*/)|(.*\*/)", RegexOptions.Singleline | RegexOptions.RightToLeft | RegexOptions.Compiled);
CSharpNumberRegex = new Regex(@"\b\d+[\.]?\d*([eE]\-?\d+)?[lLdDfF]?\b|\b0x[a-fA-F\d]+\b", RegexOptions.Compiled);
CSharpAttributeRegex = new Regex(@"^\s*(?<range>\[.+?\])\s*$", RegexOptions.Multiline | RegexOptions.Compiled);
CSharpClassNameRegex = new Regex(@"\b(class|struct|enum|interface)\s+(?<range>\w+?)\b", RegexOptions.Compiled);
CSharpKeywordRegex = new Regex(@"\b(abstract|as|base|bool|break|byte|case|catch|char|checked|class|const|continue|decimal|default|delegate|do|double|else|enum|event|explicit|extern|false|finally|fixed|float|for|foreach|goto|if|implicit|in|int|interface|internal|is|lock|long|namespace|new|null|object|operator|out|override|params|private|protected|public|readonly|ref|return|sbyte|sealed|short|sizeof|stackalloc|static|string|struct|switch|this|throw|true|try|typeof|uint|ulong|unchecked|unsafe|ushort|using|virtual|void|volatile|while|add|alias|ascending|descending|dynamic|from|get|global|group|into|join|let|orderby|partial|remove|select|set|value|var|where|yield)\b|#region\b|#endregion\b", RegexOptions.Compiled);

//block {}
 @"^[^""']*\{.*\}[^""']*$"

//start of block {}
 @"^[^""']*\{"

 //end of block {}
@"}[^""']*$"

 //label
@"^\s*\w+\s*:\s*($|//)"
@"^\s*default\s*:"

//some statements: case, default
@"^\s*(case|default)\b.*:\s*($|//)"

//is unclosed operator in previous line ?
@"^\s*(if|for|foreach|while|[\}\s]*else)\b[^{]*$"
@"(;\s*$)|(;\s*//)"))//operator is unclosed

HTML匹配：

HTMLTagRegex = new Regex(@"<|/>|</|>", RegexOptions.Compiled);
HTMLTagNameRegex = new Regex(@"<(?<range>[!\w]+)", RegexOptions.Compiled);
HTMLEndTagRegex = new Regex(@"</(?<range>\w+)>", RegexOptions.Compiled);
HTMLAttrRegex = new Regex(@"(?<range>\S+?)='[^']*'|(?<range>\S+)=""[^""]*""|(?<range>\S+)=\S+", RegexOptions.Compiled);
HTMLAttrValRegex = new Regex(@"\S+?=(?<range>'[^']*')|\S+=(?<range>""[^""]*"")|\S+=(?<range>\S+)", RegexOptions.Compiled);

SQL语句匹配：

SQLStringRegex = new Regex(@""".*?""|'.+?'", RegexOptions.Compiled);
SQLNumberRegex = new Regex(@"\b\d+[\.]?\d*([eE]\-?\d+)?\b", RegexOptions.Compiled);
SQLCommentRegex1 = new Regex(@"--.*$", RegexOptions.Multiline | RegexOptions.Compiled);
SQLCommentRegex2 = new Regex(@"(/\*.*?\*/)|(/\*.*)", RegexOptions.Singleline | RegexOptions.Compiled);
SQLCommentRegex3 = new Regex(@"(/\*.*?\*/)|(.*\*/)", RegexOptions.Singleline | RegexOptions.RightToLeft | RegexOptions.Compiled);
SQLVarRegex = new Regex(@"@[a-zA-Z_\d]*\b", RegexOptions.Compiled);
