字符串截取请大哥门指教一下

[usernamezero]

aaaaaa_122333
想截取_后边的这些数字，是怎么写的来

[51Crack]

瞎写一个：aaaaaa_122333.substring(aaaaaa_122333.indexof("_")+1)

[wangkuang5]

aaaaaa_122333.Split('_')[1]
也可以

[我姓区不姓区]

string result = System.Text.RegularExpressions.Regex.Match("aaaaaa_122333", @"_(\d+)").Groups[1].Value;

[bettymin]

上面的写法都可以.
个人比较偏好1楼的写法.

3楼的写法,要加上:using System.Text.RegularExpressions;

substring

[evaa006]

string StrTest = "aaaaaa_122333";
if(StrTest.indexof("_") >= 0 )
{
StrTest = StrTest.subString(StrTest.indexof("_") + 1);
}

[c02645]

string[] team="aaaaaa_122333".Split('_');
if(team.Length>0)
Response.Write(tean[1]);
