如何插入CookieCollection到的CookieContainer？ [英] How to insert CookieCollection to CookieContainer?

问题描述

在我从HttpWebRequest的回应，我想获得保存在另一个httbwebrequest使用它们的目的的cookie。不过，我需要插入到CookieCollection的CookieContainer。我怎么做？试图这样做：

  request.Cookiecontainer.add（response.Cookies）; 
  

但这样下去失控的错误：未将对象引用设置到对象的实例

解决方案

  request.CookieContainer =新的CookieContainer（）; 
 request.CookieContainer.Add（response.Cookies）; 
  

据微软：

的CookieContainer为空引用（在Visual Basic中为Nothing）默认情况下。你必须一的CookieContainer对象赋给属性有由的GetResponse方法返回的HttpWebResponse的饼干属性返回饼干。

After I get response from httpwebrequest, I'd like the cookies obtained to save for the purpose of using them in another httbwebrequest. However, I'd need to insert CookieCollection to CookieContainer. How do I do that? Tried to do:

request.Cookiecontainer.add(response.Cookies);

but this keeps getting out of error: Object reference not set to an instance of an object.

解决方案

request.CookieContainer = new CookieContainer();
request.CookieContainer.Add(response.Cookies);

According to Microsoft:

CookieContainer is a null reference (Nothing in Visual Basic) by default. You must assign a CookieContainer object to the property to have cookies returned in the Cookies property of the HttpWebResponse returned by the GetResponse method.
