联系网站并获取重定向 url as String in c#

Question

我注意到如果您访问 git 存储库的 url，例如
https://github.com/user/project/releases/latest
您将自动重定向到最新版本
https://github.com/user/project/releases/tag/1.3

是否有可能在 c# 中联系上述 url，被重定向并将响应 url 作为字符串？

这样我只需要执行 string.Split('/') 并获取最新的子字符串即可快速轻松地检查我的应用程序的版本。

此致，

这是我想出的（已解决）：

static void Versioncheck (double currentVersion)
    {
        //Get web response of git repository (/latest will forward you to the latest version)
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://github.com/[user]/[Project]/releases/latest");
        req.Method = "HEAD";
        req.AllowAutoRedirect = true;
        WebResponse response = (HttpWebResponse)req.GetResponse();
        //split the parts of the responseuri
        string responseUri = response.ResponseUri.ToString();
        string[] uriParts = responseUri.Split('/');
        //compare the latest part of the versionuri (version number) with the currect program version
        if (Convert.ToDouble(uriParts.Last(), CultureInfo.InvariantCulture) > currentVersion)
        {
            Console.WriteLine("Version " + uriParts.Last() + " is available! You can get the latest Version here:");
            Console.WriteLine("Project download page");
        }
        else
        {
            Console.WriteLine("Congrats! You are using the newest Version of programname!");
        }
    }
