• ASP.NET 出错页面处理


    1.新建Golbal.asax

     void Application_Error(object sender, EventArgs e) 
         {
             Exception objErr = Server.GetLastError().GetBaseException();
             string error = "发生异常页: " + Request.Url.ToString() + "<br>";
             error += "异常信息: " + objErr.Message + "<br>";
             Server.ClearError();
             Application["error"] = error;
             Response.Redirect("~/ErrorPage/ErrorPage.aspx");
         }

    2.前台部分:

    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="ErrorPage.aspx.cs" Inherits="ErrorPage" %>
    
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <title>ErrorPage</title>
    
        <script language="javascript" type="text/javascript">
    
         function CheckError_onclick() {
         var chk = document.getElementById("CheckError");
         var divError = document.getElementById("errorMsg");
         if(chk.checked)
         {
             divError.style.display = "inline";
         }
         else
         {
             divError.style.display = "none";
         }
     }
     
    
        </script>
    
    </head>
    <body>
        <form id="form1" runat="server">
        <div style="text-align: center">
            <asp:Label ID="Label1" runat="server" Text="頁面出錯了" Style="text-align: center"></asp:Label><br/>
          
            <input type="checkbox" id="CheckError" onclick="CheckError_onclick()" />查看詳細信息<br/><br/>
        </div>
        <div id="errorMsg" style="text-align: center; display:none" runat="server">
           <asp:Label ID="ErrorMessageLabel" runat="server" Text=""></asp:Label><br />
          
        </div>
        </form>
    </body>
    </html>

    3.后台把错误信息显示:

     protected void Page_Load(object sender, EventArgs e)
             {
                 ErrorMessageLabel.Text = Application["error"].ToString();
             }
