C# 使用Windows凭据将应用程序连接到Jira rest api

我的应用程序连接到Jira进行数据提取。为此，我使用了以下代码：

public string RunQuery(JiraRessource resource, string project_id, int startAt, int maxResults, string method = "GET")
{
    string url = string.Format(m_BaseUrl);
    if (project_id != null)
    {
        string jql = "search?jql=project=" + project_id;
        url = string.Format("{0}{1}", url, jql);
    }
    string jqr = "&startAt=" + startAt + "&maxResults=" + maxResults;
    url = string.Format("{0}{1}", url, jqr);
    Console.WriteLine(url);
    HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
    request.ContentType = "application/json";
    request.Method = method;
    string base64Credentials = GetEncodedCredentials();
    //string base64Credentials = WindowsIdentity.GetCurrent().Token.ToString();
    request.Headers.Add("Authorization", "Basic " + base64Credentials);
    string result = string.Empty;

    using (WebResponse response = request.GetResponse())
    {
        using (StreamReader reader = new StreamReader(response.GetResponseStream()))
        {
            result = reader.ReadToEnd();
            return result;
        }
    }
}

private string GetEncodedCredentials()
{
    string mergedCredentials = string.Format("{0}:{1}", m_username, m_password);
    byte[] byteCredentials = UTF8Encoding.UTF8.GetBytes(mergedCredentials);
    return Convert.ToBase64String(byteCredentials);
}

用户必须输入用户名和密码才能连接。我想更改它，以便使用windows凭据直接连接。我不知道该怎么做。可能吗？如果是，我怎么做

WebRequest类具有凭据属性。您可以使用新的NetworkCredential对象进行设置。您还可以将其设置为登录windows用户。样本代码

request.Credentials = new NetworkCredential(user, pwd, domain);

或

request.Credentials = CredentialCache.DefaultNetworkCredentials;
