正则表达式要匹配双引号"怎么匹配？

比如:<A href="index.htm">

要替换成<A href="search.aspx?url=index.htm">

或者:<A href="1280.htm">

要替换成<A href="search.aspx?url=1280.htm">

  string test ="<A href="1280.htm">";

  test = Regex.Replace(test, @"<a\s*href= (/ .htm}", "search.aspx?" + "$1", RegexOptions.IgnoreCase);

  MessageBox.Show(test);

不知道该如何去构造这个正则表达式了

要匹配 引号就直接去匹配引号不就行了么,不明白楼主所说意思

C# code

string

source

=

"

<A href=\"index.htm\">

"

;

string

resutl

=

Regex.Replace(source,

"

(?<=<A\\s*href=\").*?\\.htm(?=\">)

"

,

"

search.aspx?url=$0

"

); Console.WriteLine(resutl);

比如: <A href="index.htm">

要替换成 <A href="search.aspx?url=index.htm">

或者: <A href="1280.htm">

要替换成 <A href="search.aspx?url=1280.htm"> 

转义下就可以拉 \"

  string str = "<A href=\"1280.htm\">";

  str = str.Replace("href=\"", "href=\"search.aspx?url=");

  Console.WriteLine(str);

  Console.ReadKey();
