string str = "aaaaaaa_bbbbbbb";
int index = str.IndexOf("_");
int length = str.Length;
if(index + 1 >= length)
{
    //最后一个字符是"_"，不能截取
    return;
}
string resultStr = str.SubString(index + 1, length - index - 1);

string str = "aaaaa_bbbbb";
string []strs = str.split('_');
if(strs.length > 1)
messagebox.show(strs[1]);
