只要在Web.Config中添加如下代码即可。
<
system.web
>
< customErrors mode ="On" defaultRedirect ="~/Error.aspx" <!--全局性的 推荐mode为 RemoteOnly:本机查看详细错误信息，其他机器查看定制的错误页面 -->
< error statusCode ="404" redirect ="~/404.html" /> <!--局部性的,可以添加404，403等已知错误-->
</ customErrors >
</ system.web >
< customErrors mode ="On" defaultRedirect ="~/Error.aspx" <!--全局性的 推荐mode为 RemoteOnly:本机查看详细错误信息，其他机器查看定制的错误页面 -->
< error statusCode ="404" redirect ="~/404.html" /> <!--局部性的,可以添加404，403等已知错误-->
</ customErrors >
</ system.web >
可以在Error.aspx中写代码，把错误信息写到日志文件中
using
System;
using System.Web;
using System.IO;
namespace GridView入库单管理
{
public partial class Error : System.Web.UI.Page
{
protected void Page_Load( object sender, EventArgs e)
{
if ( ! IsPostBack)
{
Exception ex = HttpContext.Current.Server.GetLastError(); // 获取错误对象；
string line = " ------------------------------------------------------------------------------ " ;
File.AppendAllText(Server.MapPath( " ~/Log.txt " ), ex.Message + ex.StackTrace + " \n " + DateTime.Now + " \n " + line);
}
}
}
using System.Web;
using System.IO;
namespace GridView入库单管理
{
public partial class Error : System.Web.UI.Page
{
protected void Page_Load( object sender, EventArgs e)
{
if ( ! IsPostBack)
{
Exception ex = HttpContext.Current.Server.GetLastError(); // 获取错误对象；
string line = " ------------------------------------------------------------------------------ " ;
File.AppendAllText(Server.MapPath( " ~/Log.txt " ), ex.Message + ex.StackTrace + " \n " + DateTime.Now + " \n " + line);
}
}
}
}
生成的错误信息格式：（用404测试的）
