怎么分别取出qy2151251251，HOIASFD，laify？

看到这样的东西，别把他看成普通字符串 看到这样的东西，你心里应该想这是个json字符串，so “C# json字符串”

json反序列化可以实现。正则表达式可以实现，字符串拆分也能实现。看你要用那种了

估计是完整的json串，你复制了一段 正则提取

string input = @"]},{userid:qy2151251251,name:
                ]},{userid:HOIASFD,name:
                ]},{userid:laify,name:";

foreach(Match m in Regex.Matches(input, @"(?<=userid:).+?(?=,)"))
{
    Response.Write(m.Value.ToString()+"<br />");

}
