ASP.NET的四种错误机制[转帖]

1.Webconfig设置
 

  <?xml version="1.0"?>
    <configuration>
  <system.web>
  <customErrors mode="On" defaultRedirect="GenericErrorPage.htm">
  <error statusCode="403" redirect="Error403.htm" />
  <error statusCode="404" redirect="Error404.htm" /> 
  </customErrors>
  </system.web>
  </configuration>

 

  2,Global.asax设置

515down.com

  protected void Application_Error(object sender, EventArgs e) {
  Exception objErr = Server.GetLastError().GetBaseException();
  Response.Write("Error:" + objErr.Message);
  Server.ClearError();
  }

 

  3,使用ErrorPage属性

  <script language="C#" runat="server">
  protected void Page_Load(object sender, EventArgs e) {
        this.ErrorPage = "ErrorPage.htm";
        }  
  </script>

515down.com

  4,使用Page_Error事件处理方法
  protected void Page_Error(object sender, EventArgs e) {
  Exception objErr = Server.GetLastError().GetBaseException();
  Response.Write("Error:" + objErr.Message);
  Server.ClearError(); //同样要注意这句代码的使用
  } 

 

  根据优先级从高到低排序:Page_Error事件处理方法 > ErrorPage属性 > Application_Error事件处理方法 >  <customErrors>配置项。
