MVC 3：CustomResult（）找不到合適的方法來覆蓋

Question

我正在創建一個imageresult ..但「公共覆蓋無效ExecuteResult（ControllerContext上下文）」說：找不到合適的方法覆蓋。

我的課是這樣的..

public override void ExecuteResult(ControllerContext Context) 
    { 
     byte[] bytes; 
     string contentType = GetContentTypeFromFile(); 

     //if there's no context, stop the processing 
     if (Context == null) 
     { 
      throw new ArgumentNullException("context"); 
     } 

     //check for file 
     if(File.Exists(_path)){ 
      bytes = File.ReadAllBytes(_path); 
     } 
     else{ 
      throw new FileNotFoundException(_path); 
     } 


     // 
     HttpResponseBase response = Context.HttpContext.Response; 
     response.ContentType = contentType; 

     MemoryStream imageStream = new MemoryStream(bytes); 

     byte[] buffer = new byte[4096]; 

     while (true) 
     { 
      int read = imageStream.Read(buffer, 0, buffer.Length); 

      if (read == 0) 
       break; 

      response.OutputStream.Write(buffer, 0, read); 
     } 

     response.End(); 

    }

請問您的類的子類ActionResult？請嘗試以下操作：

using System.Web.Mvc; 

public class ImageResult : ActionResult 
{ 
    public override void ExecuteResult(ControllerContext Context) 
    { 
    ... 
    } 
}
