HttpResponse.SubStatusCode 属性

public:
 property int SubStatusCode { int get(); void set(int value); };

public int SubStatusCode { get; set; }

member this.SubStatusCode : int with get, set

Public Property SubStatusCode As Integer

属性值

表示 IIS 7.0 子状态代码的整数值。

示例

以下示例在事件实例的PostAuthenticateRequest事件处理程序HttpApplication中设置 SubStatusCode 属性。 将代码文件放在 Web 应用程序的 App_Code 文件夹中，并将 Web.config 文件配置为注册模块。 有关详细信息，请参阅 演练：创建和注册自定义 HTTP 模块。

注解

SubStatusCode只有 IIS 7.0 中的集成管道模式和至少.NET Framework版本 3.0 才支持 属性。 设置 SubStatusCode 属性时，如果配置了失败的请求跟踪，则会在 IIS 7.0 上记录状态。 与是否配置跟踪无关，代码永远不会作为对请求的最终响应的一部分发送。 有关详细信息，请参阅 在 IIS 7.0 中使用失败的请求跟踪排查失败的请求问题。
