asp.net自定义错误页面

两种方法均为全站出错处理

方法一：

1、添加Web.config， <system.web></system.web>中添加<customErrors mode="On"

defaultRedirect="ApplicationErroy.aspx" ></customErrors>节点，

2、添加错误处理页面：ApplicationErroy.aspx调用下面的方法：

private void DealErroy()

{

HttpException erroy = new HttpException();

string strCode = erroy.ErrorCode.ToString();

string strMsg = erroy.Message;

erroy.HelpLink = "sss";

Response.Write("ErrorCode:" + strCode + "<br>");

Response.Write("Message:" + strMsg + "<br>");

Response.Write("HelpLink:" + erroy.HelpLink + "<br>");

Response.Write("Source:" + erroy.Source + "<br>");

Response.Write("TargetSite:" + erroy.TargetSite + "<br>");

Response.Write("InnerException:" + erroy.InnerException + "<br>");

Response.Write("StackTrace:" + erroy.StackTrace + "<br>");

Response.Write("GetHtmlErrorMessage:" + erroy.GetHtmlErrorMessage() + "<br>");

Response.Write("erroy.GetHttpCode().ToString():" + erroy.GetHttpCode().ToString() +

"<br>");

Response.Write("erroy.Data.ToString()::" + erroy.Data.ToString() + "<br>");

}

这种方法不能完整地显示错误信息；

方法二：

1、添加Web.config， <system.web></system.web>中添加<customErrors mode="On"

defaultRedirect="ApplicationErroy.aspx" ></customErrors>节点，

2、添加Global.asax文件，找到Application_Error事件，加入以下代码：

Exception erroy = Server.GetLastError();

string err = "出错页面是：" + Request.Url.ToString() + "<br>";

err += "异常信息：" + erroy.Message + "<br>";

err += "Source:" + erroy.Source + "<br>";

err += "StackTrace:" + erroy.StackTrace + "<br>";

Server.ClearError();

Application["erroy"] = err;

2、添加错误处理页面：ApplicationErroy.aspx 加入以下代码；

Response.Write(Application["erroy"].ToString());

这种方法能完整地显示错误信息，

最好的办办法还是两种方法一起用最好！

另:web.config中也可以把

<error statusCode="403" redirect="NoAccess.htm" />//访问被禁止

<error statusCode="404" redirect="FileNotFound.htm" />//找不到页面

添加进去
