如何使用c#使用Youtube api登录程序？

有this文档。可用的。所以我用了

YouTubeRequestSettings settings = new YouTubeRequestSettings("Appname","devkey", textBox1.Text, textBox2.Text);
request = new YouTubeRequest(settings);

Video newVideo = new Video();
newVideo.Title = "Test";
newVideo.Tags.Add(new MediaCategory("Animals", YouTubeNameTable.CategorySchema));
newVideo.Description = "Testing Testing Testing";
newVideo.YouTubeEntry.Private = false;
newVideo.YouTubeEntry.MediaSource = new MediaFileSource("C:\\BabyBoyScenesBackground_PAL.wmv", "video/x-ms-wmv");
try
{
  request.Upload(newVideo);
}
catch (Exception ccc)
{
  MessageBox.Show(ccc.ToString());
}

只是为了获得401授权。我需要改变什么。如果你问，我发现的所有资源要么已经过时，要么人们没有处理这个问题。

对于“Appname”、“devkey”，我使用了适当的值以及密码和用户名。

恐怕在这种情况下，正如预期的 401 未经授权的错误一样，您必须提供不正确的详细信息。我不厌其烦地尝试了你的代码，它按预期工作，并上传了视频。您的 devkey、密码或用户名一定不正确，或者上面发布的代码之外一定存在问题，因为它对我来说工作得很好。

但是，您确实应该使用后台工作者来完成此任务，也许像这样：

namespace YouTube
{
    using System;
    using System.ComponentModel;
    using System.Windows;

    using Google.GData.Client;
    using Google.GData.Extensions.MediaRss;
    using Google.GData.YouTube;
    using Google.YouTube;

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private static BackgroundWorker uploader;

        private static YouTubeRequestSettings settings;

        static void UploaderDoWork(object sender, DoWorkEventArgs e)
        {
            var request = new YouTubeRequest(settings);
            var newVideo = new Video { Title = "Test" };
            newVideo.Tags.Add(new MediaCategory("Animals", YouTubeNameTable.CategorySchema));
            newVideo.Description = "Testing Testing Testing";
            newVideo.YouTubeEntry.Private = true;
            newVideo.YouTubeEntry.MediaSource = new MediaFileSource("C:\\Wildlife.wmv", "video/x-ms-wmv");            
            try
            {
                request.Upload(newVideo);
            }
            catch (Exception exception)
            {
                MessageBox.Show("Upload failed: " + exception.Message);
            }
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            settings = new YouTubeRequestSettings(
                "app",
                "devkey",
                "email",
                "password");
            uploader = new BackgroundWorker { WorkerReportsProgress = true, WorkerSupportsCancellation = true };
            uploader.DoWork += UploaderDoWork;
            uploader.RunWorkerCompleted += delegate { MessageBox.Show("Upload completed!"); };
            uploader.RunWorkerAsync();
            MessageBox.Show("Initiated upload...");
        }
    }
}

希望你能解决！
