在HttpWebRequest中从C# WinApp设置cookie

Question

我正试着用c# winapp做一个c#。

我从google开发工具获得了以下请求头(省略了不必要的部分)-

Cookie: PHPSESSID=f530kslitnsq7uho33auebkd11;ciIPPBXOBd=TOAf5yvdIlHf7Ak%3D

我的密码是-

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("example.com");
Cookie cookie = new Cookie("PHPSESSID", "f533auebkd11") { Domain = "example.com" };
request.CookieContainer.Add(cookie);

但是我在最后一行中得到了对象引用空错误。

如何摆脱？

默认情况下，cookie容器为空。尝尝这个。

   HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.google.com");
        Cookie cookie = new Cookie("PHPSESSID", "f533auebkd11") { Domain = "example.com" };
        //if cookie contaner is null then try new container
        request.CookieContainer =  request.CookieContainer ?? new CookieContainer();
        request.CookieContainer.Add(cookie);
