在Web Api中返回Zip文件作为响应

-2

嗨我创建了一个web api应用程序，并且我将响应作为文本文件返回。现在我想回到一个压缩文件，使其尺寸减小在Web Api中返回Zip文件作为响应

这是我的控制器代码

public HttpResponseMessage Get(String parameter) 
    { 
     var response = new HttpResponseMessage(HttpStatusCode.OK); 
     response.Content = new StringContent(informationcontext.Records(parameter)); 
     response.Content.Headers.ContentType = new MediaTypeHeaderValue("text/plain"); 
     response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment") 
     { 
      FileName = "sample" 
     }; 


     return response;

}

任何一个可以帮助我在这？
