菜鸟请教个问题

[caoning1185]

昨天还能看呢,我忘记改IIS什么地方了，再登陆就是这个问题。请教高手。

我的IIS里面有这些东西：

[暗尘掩月]

跟iis没有任何关系 代码的问题

[caoning1185]

我没动过代码

[若-相惜]

没取到值啊 贴代码

[昵称不能为空噢噢噢噢]

跟iis有毛关系。跟你自己写的代码有问题

[zc920315]

应该是没有取值或是你的控件绑定错误。

[caoning1185]

代码我也贴过,查不出原因

[ShenYong2013]

先看看代码中是否有对象没有判断是否存在什么的吧

using System;
using System.Configuration;

using System.Web.Security;

public partial class _Default : System.Web.UI.Page
{

{
if (CookieHelper_Cai.HaveCookie("WaterFee", "Uname"))
{
Response.Redirect("HomeS.aspx");
}
else
{

}
}

protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
string names = "";
string pwd = "", ip = "";
names = this.UnameS.Text.Trim();
pwd = this.Pawd.Text.Trim();

if (!string.IsNullOrEmpty(names) && !string.IsNullOrEmpty(pwd))
{
ip = RequestSafe_Cai.GetIP();
pwd = MD5_Cai.Encrypt(pwd);
if (AdminUserSExecutSqlS.Admin_User_LoginIn(names, pwd, ip))
{
DataTable dt = new DataTable();
dt = AdminUserSExecutSqlS.Admin_User_ShowOneByUname(names);
if (dt != null)
{
if (dt.Rows.Count > 0)
{
CookieHelper_Cai.AddCookie("WaterFee", "Uname", names, 1);
CookieHelper_Cai.AddCookie("WaterFee", "Uid", dt.Rows[0]["ad_ID"].ToString(), 1);
CookieHelper_Cai.AddCookie("WaterFee", "Utruename", System.Web.HttpUtility.UrlEncode(dt.Rows[0]["ad_userTrueName"].ToString()), 1);
Response.Redirect("Default.aspx");
}
else
{
JSscript.AlertAndGoTo("用户名密码正确，但未设定真实姓名，请联系管理员", "Default.aspx");
Response.End();
}
}
else
{
JSscript.AlertAndGoTo("用户名密码正确，但未设定真实姓名，请联系管理员", "Default.aspx");
Response.End();
}
}
else
{
JSscript.AlertAndGoTo("登录失败，可能用户名密码不正确", "Default.aspx");
Response.End();
}
}
else
{
JSscript.AlertAndGoTo("帐号和密码都不能为空", "Default.aspx");
Response.End();
}

}
}

估计是最后更新用户用户这段代码有问题.请教高手。

原文在这:http://topic.csdn.net/u/20120807/10/87edf857-0c87-4ce8-b87a-48b71e9508c0.html?seed=1501983708&r=79336374#r_79336374,

[你们是不是在找BUG]

空引用异常。什么地方出现的异常你就在哪里debug

[lee3217813]

你贴的图片不是给了两个解决办法吗

[csl_1022]

按照提示改呗

[caoning1185]

确实是WEB.CONFIG 问题，再里面加一行 <compilation debug="true">就OK了。
