WCF 4.0自托管Json服务中的自定义HTTP状态时出错 [英] Error While Custom HTTP Status in WCF 4.0 Self Hosted Json Service

问题描述

嗨专家，



我有一个WCF自托管JSon服务，

我想从我的服务返回自定义HTTP状态代码。

设置HTTP状态的代码如下所示。

  public   void  SetResponseHttpStatus（HttpStatusCode statusCode）
 {
  try  
 {
 OutgoingWebResponseContext response = WebOperationContext.Current.OutgoingResponse; 
 response.StatusCode = statusCode; 
 
  //   WebOperationContext context = WebOperationContext.Current;  
 < span class =code-comment> //   context.OutgoingResponse.StatusCode = statusCode;  
} 
  catch （例外）
 {} 
} 

但以上代码是对象引用.........的例外;



我可以解决任何问题......？

请尽快帮助我

解决方案

  public  < span class =code-keyword> class  MyService：IMyService 
 {
 
  //   GENERAL / GLOBAL DECLARATION  
  private  OutgoingWebResponseContext响应; 
 
  //  这是您的服务功能，将在呼叫服务期间执行 
  public   string  MyServiceFunction（BLAA ..，BLAA ...）
 { 
  //  指定对象全球声明 
 response = WebOperationContext.Current.OutgoingResponse ; 
 SetResponseHttpStatus（HttpStatusCode.OK）; 
} 
 
  private   void  SetResponseHttpStatus（HttpStatusCode statusCode）
 {
 尝试 
 {
  //   SET STATUS TO RESPONSE  
 response.StatusCode = statusCode; 
} 
  catch （例外）
 {} 
} 
 
}
