I want to set a cookie value for a http POST request, caqn this be done in Silverlight?

If so which开发者_StackOverflow中文版 class should I use HttpWebRequest, WebCLient or something else?


I think you can define the headers with the HttpWebRequest, so it's easy just define the Cookie header with the correct value, you can find a little help here.


To set the cookie:

HtmlPage.Document.SetProperty("cookie", value);

where value is something like "mykey=abcdef;". To read it (key in this case is "mykey":

string[] cookies = HtmlPage.Document.Cookies.Split(';');
foreach (string cookie in cookies)
{
    string[] keyValuePair = cookie.Split('=');
    if (keyValuePair.Length == 2 && key == keyValuePair[0].Trim())
        return keyValuePair[1].Trim();
}

To delete it:

string oldCookie = HtmlPage.Document.GetProperty("cookie") as String;
DateTime expiration = DateTime.UtcNow - TimeSpan.FromDays(1);
string cookie = String.Format("{0}=;expires={1}", key, expiration.ToString("R"));
HtmlPage.Document.SetProperty("cookie", cookie);
