C# 上传视频到youtube时，我如何知道什么类别id是什么类别名称？

我正在向yourube上传视频： 在form1构造函数中：

UserCredential credential;
            using (FileStream stream = new FileStream(@"D:\C-Sharp\Youtube-Manager\Youtube-Manager\Youtube-Manager\bin\Debug\client_secrets.json", FileMode.Open, FileAccess.Read))
            {
                credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                    GoogleClientSecrets.Load(stream).Secrets,
                    new[] { YouTubeService.Scope.Youtube, YouTubeService.Scope.YoutubeUpload },
                    "user",
                    CancellationToken.None,
                    new FileDataStore("YouTube.Auth.Store")).Result;
            }
            var youtubeService = new YouTubeService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
            });
            var video = new Video();
            video.Snippet = new VideoSnippet();
            video.Snippet.Title = "Default Video Title";
            video.Snippet.Description = "Default Video Description";
            video.Snippet.Tags = new string[] { "tag1", "tag2" };
            video.Snippet.CategoryId = "22"; // See https://developers.google.com/youtube/v3/docs/videoCategories/list
            video.Status = new VideoStatus();
            video.Status.PrivacyStatus = "public";
            var filePath = @"C:\Users\bout0_000\Videos\test.mp4";
            using (var fileStream = new FileStream(filePath, FileMode.Open))
            {

                const int KB = 0x400;
                var minimumChunkSize = 256 * KB;

                var videosInsertRequest = youtubeService.Videos.Insert(video,
                    "snippet,status", fileStream, "video/*");
                videosInsertRequest.ProgressChanged +=
                    videosInsertRequest_ProgressChanged;
                videosInsertRequest.ResponseReceived +=
                    videosInsertRequest_ResponseReceived;
                videosInsertRequest.ChunkSize = minimumChunkSize * 4;
                videosInsertRequest.Upload();
            }

在这个例子中，我使用的是分类号22

video.Snippet.CategoryId = "22";

只有在上传了我在youtube网站上看到的视频后，我的视频中才发现这个类别是：人物和博客

如果我浏览到这个链接，我可以使用底部的OAuth 2.0来处理授权请求

但我还是不明白在哪里可以看到按姓名和id列出的所有类别的完整列表？例如：Name:People&Blogs Id:22

找不到任何显示它的站点。

对以下站点进行API调用：

https://www.googleapis.com/youtube/v3/videoCategories?part=snippet&regionCode={two-character-region}&key={YOUR_API_KEY}

---

API将返回所选区域的所有类别（名称和ID）。请注意，同一类别在所有地区都应具有相同的ID；但是，某些类别在某些区域中不可用（这就是您必须执行API调用的原因…区域太多，无法以友好的方式列出所有可能的排列）。

下面是我程序中的VB.NET源代码。此代码加载带有自定义类（CategoryClass）的组合框，该类包括所有有效的CategoryId和标题。我还包括了我的自定义类：CategoryClass。您可以使用其中一个免费转换器将其转换为C#.NET

---

我可以手动使用上面的链接，给它区域代码和我的api密钥，它就可以工作了。但是我如何在csharp代码中实现它呢？你能给我举个例子吗？例如：该区域是IL，我正在使用我的api密钥。但是我如何在我的c#代码中使用i，这样我就可以得到区域所有类别的字符串列表，并将这些类别添加到一个组合框中。当我使用区域和我的api键浏览此链接时，它会起作用。我只是不知道如何在我的代码中实现它，我的问题是如何在我的代码中植入它。
