ErrorPage.aspx
<head runat="server">
<title>出错信息</title>
<link href="css/SITE.CSS" type="text/css" rel="stylesheet" />
</head>
<body>
<form id="form1" runat="server">
<asp:Label ID="Label1" runat="server" Width="568px"></asp:Label>
</form>
</body>
ErrorPage.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
this.Label1.Text = Application["Error"].ToString();
}
当然，错误页你可以不显示具体的错误信息,而是给用户一个友好的提示页面。
