Answer 1

aspx.cs:71，告诉你第几行了，调试

Answer 2

贴点代码出来！本地调试通不代表服务器就可以。就好比本地调用你本地的webservice取值如果挂到服务器上没改配置文件或者调用的路径不对同样也有可能报这种错误

Answer 3

配置文件是改了的  主要在服务器上没有环境，不然我也就调试了，首页的cs代码：

Answer 5

好长的意大利面条，大体一看没有注意到给Session赋值的地方只注意到使用Session的地方了

Answer 6

ED_JB_RegisterInfo user = Session["userinfo"] as ED_JB_RegisterInfo;
这里使用的Session["userinfo"] 赋值了吗？
