登录时报错 ‘null’为空或不是对象

StringBuilder sb = new StringBuilder();

this.RegisterStartupScript("loginok",sb.ToString());

怀疑是最后一句的问题，请高手帮分析分析

this.RegisterStartupScript("loginok",sb.ToString());

==================>

Page.ClientScript.RegisterStartupScript(this.GetType(),"loginok",sb.ToString());

先确定一下是后台报错还是前台js报错。。

另外，建议注册脚本不要这样写，因为.net 2.0以后不建议这么写了（这个记得不是很清楚了）

改为：

this.Page.ClientScript.RegisterStartupScript(this.GetType(), "", "脚本代码str");

呵呵 你自己打断点不就知道了吗

[子夜__]

 this.ClientScript.RegisterStartupScript(GetType(), "loginok", sb.ToString());
