错误处理机制代码

protected void Application_Error(object sender, EventArgs e)
        {
            HttpContext ctx = HttpContext.Current;
            Exception exception = ctx.Server.GetLastError();
           // Exception exception_s = Server.GetLastError();
            //HttpException ex = exception_s as HttpException;
            string directUrl = "Error.aspx?error=";
            if (exception != null)
            {
                string m = exception.Message;

string errorInfo = "URL:" + ctx.Request.RawUrl.ToString() + " Source:" + exception.Source
 + " Message:" + exception.Message + "<>";
 if (!m.Contains("不存在"))
 {
 errorInfo += " 错误信息为:" + exception.InnerException.Message + "<>";
 }
 if (exception is HttpException)
 {
 HttpException ex = exception as HttpException;
 int httpCode = ex.GetHttpCode();
 errorInfo += " Code:" + httpCode.ToString() + "<>";
 }
 string url = ctx.Request.Url.ToString();
 string suburl = url.Substring(0, url.ToString().IndexOf("/Admin/") + 1);
 directUrl = suburl + directUrl + errorInfo;
 //directUrl += "&referurl=" + ctx.Request.Url.ToString();
 //if (httpCode == 404)
 //{
 // directUrl = "~/DefaultError.html?error=" + errorInfo;
 //}
 //if (httpCode == 403 || httpCode == 402 || httpCode == 401)
 //{
 // directUrl = "~/DefaultError.html?error=" + errorInfo;
 //}
 //}
 ctx.Items.Add("LastError", errorInfo);
 ctx.Server.ClearError();
 }
 try
 {
 ctx.Response.Redirect(directUrl);
 }
 catch
 { }
 //ctx.Server.Transfer(directUrl);
 }
错误处理机制代码，要的赶紧粘贴到记事本
就写一个方法，页面所有报错都指向一个页面就OK了

这个方法必须写在 Global.asax 文件中，放在根目录
