网络凭据未保存在CredentialCache中

Question

我必须将凭据缓存中的用户名和密码分配给Httpwebrequest。当我分配给缓存时，它正在工作，但当从缓存分配给Webrequest时，它显示为null。我哪里错了？

string strServer = "";
        strServer = "http://servername/";
        Uri uri = new Uri(strServer);
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
        CredentialCache cache = new CredentialCache();  
        cache.Add(new Uri(strServer), "Basic", new System.Net.NetworkCredential("username", "password","Domain"));
        cache.Add(new Uri(strServer), "Digest", new System.Net.NetworkCredential("username", "password","Domain"));
        request.Credentials = cache;

你好您只需要从缓存中检索凭据，然后将其添加到web请求中，示例如下：

    cache.Add(new Uri(strServer), "Basic", new System.Net.NetworkCredential("username", "password","Domain"));
    cache.Add(new Uri(strServer), "Digest", new System.Net.NetworkCredential("username", "password","Domain"));    
    NetworkCredential  currentCredentials= cache.GetCredential(new Uri(strServer), "Basic");  //Get specific credential
    request.Credentials = currentCredentials; //Allocate credential
