[解决办法]
- 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); }
[解决办法]
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);
}
