C＃中获取内容类型的响应，而无需加载全部内容 [英] C# Get content type of a response without loading entire content

问题描述

我要确保从那些谁知道，如果下面的代码行只会请求的响应类型，而无需加载的全部内容，因为我必须在我的应用程序的一些条件在响应类型，我不想浪费时间应该被忽略的资源。

 要求=（HttpWebRequest的）System.Net.HttpWebRequest.Create（URL） ; 
响应=（HttpWebResponse）request.GetResponse（）; 
变种的responseType = response.ContentType; 
  

解决方案

这可能是最容易设置的 方法属性到HEAD - 这样你不会得到实际的内容，就在标题

在另一方面，这并不意味着你需要做出两个请求，当你的不的想要的内容...

I want to make sure from those who know if the following lines of code will only get the response type of the request without loading the full content, because i have to to some conditions over response type in my application and i dont want to waste time for that resources that should be ignored.

request = (HttpWebRequest)System.Net.HttpWebRequest.Create(url);
response = (HttpWebResponse)request.GetResponse();
var responseType = response.ContentType;

解决方案

It's probably easiest to set the Method property to "HEAD" - that way you won't get the actual contents, just the headers.

On the other hand, that does mean you'll need to make two requests when you do want the contents...
