得到内容后正则匹配

 string tempStr = @"callback( {""client_id"":""100221326"",""openid"":""99BD8F025CF73F24E2D738DBA11EFA79""} );"; //            string pattern = @"(?im)(?<=['""]?openid['""]?:['""])[^'""\s]+";
            string output = Regex.Match(tempStr, pattern).Value;//输出：99BD8F025CF73F24E2D738DBA11EFA79

string tempStr = @"callback( {""client_id"":""100221326"",""openid"":""99BD8F025CF73F24E2D738DBA11EFA79""} );";             string pattern = @"(?im)(?<=['""]?openid['""]?:['""])[^'""\s]+";
            string output = Regex.Match(tempStr, pattern).Value;//输出：99BD8F025CF73F24E2D738DBA11EFA79
