asp中这样子的语句怎么用C#写呢？

' ============================================
' 按照指定的正则表达式返回字符

Public Function RegExpSearch(Patrn, Str, sType, Spacer)
Dim RegEx, Match, Matches , RetStr, i
i = 0
Set RegEx = New RegExp
RegEx.Pattern = Patrn
RegEx.IgnoreCase = True
RegEx.Global = True
Set Matches = RegEx.Execute(Str)
For Each Match In Matches
i = i + 1
If sType = 0 Then
RetStr = RetStr & Match.Value
If i < Matches.Count Then RetStr = RetStr & Spacer
Else
RetStr = RetStr & Match.Value
If i < Matches.Count Then RetStr = RetStr & Spacer
If sType = i Then Exit For
End If
Next
RegExpSearch = RetStr
End Function

If InStr(LCase(DomainFix), LCase(Replace(CStr(iXs.RegExpSearch("\.(" & DomainFix & ")$", Domain, 1, "")), ".", ""))) = 0 Then Call iXs.Alert("您的域名后缀错误！或者当前系统拒绝此后缀的域名查询。\n\n请检查后重新输入或者联系管理员！", 0, 0) ' 应当以标准的域名后缀结尾

DomainFix= "net|com|cn|org|cc|tv|info|tw|biz|sh|ws|name|ac|io" ' 可以查询的域名后缀

你可以用Regex来替换asp中的RegExp

参看msdn中的帮助

这段用C#怎么写呢各位老大

自己搞定

[kingwkb]

对，在.net中正则用Regex，具体可以查msdn

[coyprightbao]

又是个VB.net,现在用这个做什么项目比较多？
