C#从字符串创建cookie并发送它

我想向HTTP服务器发出POST请求，但我需要在请求中“包含”一个cookie，我有cookie，但我不知道如何处理cookie容器

HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.Method = "POST";
request.Accept = "text/javascript, text/html, application/xml, text/xml, */*";
request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
request.Host = "url.com";
request.UserAgent = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1132.47 Safari/536.11";
request.Referer = "http://url.com";
request.Headers.Add("X-Requested-With", "XMLHttpRequest");
request.Headers.Add("X-Prototype-Version", "1.7");
request.Headers.Add("Accept-Encoding: gzip, deflate");

这是一个示例cookie：

Cookie recentlyVisitedAppHubs=233450%2C231430%2C48110%2C45760； 语言=西班牙语；strInventoryLastContext=440_2； __utma=268881843.118202637.1372069740.1373472452.1373473085.10__utmb=268881843.21.10.1373473085__utmz=268881843.1373473085.10.4.utmcsr=google | UTMCN=（有机）| utmcmd=有机| utmctr=（未提供%20）； rgTopicView_General_4312225=%7B%2282893491339632649%22%3A%22137345285%22%2C%22846939615003500718%22%3A1373473557%7D； 时区偏移=7200,0；sessionid=NDExNjE1NDE5； 登录名=765611979917322708A9C768；steamRememberLogin=76561197991732272； __utma=268881843.118202637.1372069740.1373472452.1373473085.10__utmb=268881843.22.10.1373473085__utmc=268881843__utmz=268881843.1373473085.10.4.utmcsr=google | utmccn=（有机）| utmcmd=organic | utmctr=（未提供%20）

但是我不知道如何将cookie转换为cookie容器，然后将其添加到请求中。 request.CookieContainer=cookie

//build uri and cookie
Uri uri = new Uri("domain");
Cookie cookie = new Cookie("name", "value");

//build request
HttpWebRequest request = WebRequest.Create("domain") as HttpWebRequest;
request.CookieContainer = new CookieContainer();
request.CookieContainer.Add(uri, cookie);

但我只有字符串，没有CookieCollection对象。更新了构建Cookie对象的答案。仍然没有回答问题。欢迎使用堆栈溢出！请写一篇关于你的代码的解释，以及它是如何不同的，以便其他人能够理解！从字符串创建cookie

String CookieStr = "recentlyVisitedAppHubs=233450%2C231430%2C48110%2C45760; 
Language=spanish; strInventoryLastContext=440_2";
CookieContainer cookiecontainer = new CookieContainer();
string[] cookies = CookieStr.Split(';');
foreach (string cookie in cookies)
   cookiecontainer.SetCookies(new Uri("http://url.com"), cookie);
request.CookieContainer = cookiecontainer;
