ASP.NET自定义错误处理页面的添加

asp.net自定义错误处理页面方法一

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；

asp.net自定义错误处理页面方法二

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

http错误代码含义：

"100" : Continue

"101" : witching Protocols

"200" : OK

"201" : Created

"202" : Accepted

"203" : Non-Authoritative Information
