我想取得thumbURL，怎么取？求解。正则我稀烂的。

------解决方案--------------------

C# code


            StreamReader reader = new StreamReader("c:\\1.txt",Encoding.Default);
            string source = reader.ReadToEnd();
            Regex reg = new Regex(@"(?is)(?<=""thumbURL""[^""]*?)""http:.*?""");
            MatchCollection mc = reg.Matches(source);
            foreach (Match m in mc)
            {
                MessageBox.Show(m.Value);
            }

------解决方案--------------------

   string source = "{\r\n                \"queryEnc\": \"%D7%C0%C3%E6%B1%DA%D6%BD\",\r\n                \"displayNum\": 9921457,\r\n                \"bdIsClustered\": \"1\",\r\n                \"listNum\": 2000,\r\n                \"bdFmtDispNum\": \"9921457\",\r\n                \"thumbURL\": \"http://t1.baidu.com/it/u=3917541605,2488848911&fm=0&gp=0.jpg\",\r\n                \"bdSearchTime\": \"0.043\"\r\n                 },\r\n                 {\r\n                \"queryEnc\": \"%D7%C0%C3%E6%B1%DA%D6%BD\",\r\n                \"displayNum\": 9921457,\r\n                \"bdIsClustered\": \"1\",\r\n                \"listNum\": 2000,\r\n                \"bdFmtDispNum\": \"9921457\",\r\n                \"thumbURL\": \"http://t1.baidu.com/it/u=3917541605,2488848911&fm=0&gp=0.jpg\",\r\n                \"bdSearchTime\": \"0.043\"\r\n                 }\r\n";





      var matches= Regex.Matches(source, @"(?is)(?<=thumbURL\"":\s*\"")[^""]+(?="")");
       foreach(Match m in matches)
       {
           Response.WriteLine(m.Value);
       }

------解决方案--------------------

(?i)(?<=thumbURL[^:]+?\s*?['""])[^'""]+

------解决方案--------------------

C# codeRegex reg = new Regex(@"(?i)(?<=""thumbURL""\s*:\s*"")[^""]*(?="")");
MatchCollection mc = reg.Matches(yourStr);
foreach (Match m in mc)
{
    richTextBox2.Text += m.Value + "\n&quo
