问题描述

大家好，

我是新来的C＃编程的新手很抱歉如果我丢失的东西是b $ b不允许在论坛中使用。



我正在尝试实施一种软件，可以（在第一阶段）显示YouTube用户的播放列表列表，

使用Windows窗体应用程序。



我看到一些视频和文章很安静，并查看了Google API网站，但我有遗漏了一些东西。



我基于这个网站上出现的代码 - https://automatetheplanet.com/youtube-playlists-api-csharp -code /
$


这是我开始使用的形式 -

Hi to all,
I'm new here and new to C# programming so sorry if I'm
missing things which aren't allowed in the forum.

I'm trying to implement a software which can (at the first stage) display a list of a YouTube user's playlists,
using a windows form application.

I've see quiet a few videos and articles, and viewed the Google API site, but I have some things missing out.

I'm Basing myself on the code as appears in this site - https://automatetheplanet.com/youtube-playlists-api-csharp-code/

This is what I've started with in at my form -

namespace YouTubeTest
{
    public partial class FormGetPlaylist : Form
    {
        public FormGetPlaylist()
        {
            InitializeComponent();
        }

        private void buttonGoclick_Click(object sender, EventArgs e)
        {
            listBoxPlaylists.Items.Clear();

            string userEmail = textBoxUsersName.Text;
            List<YouTubePlayList>

            //YouTubeVideo[] playlists = YouTubeAPI.GetPlaylist(userEmail);

            foreach (var playlist in playlists)
            {
                listBoxPlaylists.Items.Add(playlist);
            }


        }
    }
}

如何与下面的"GetUserPlayLists"功能进行交互，以获取播放列表列表？


下面的代码部分存在于名称空间YouTubePlaylistAPI下的另一个文件"YouTubeServiceClient"中：

how do I interact with the function 'GetUserPlayLists' below so to get the list of playlists ?
the part of code below exists in a different file , 'YouTubeServiceClient', under the namespace YouTubePlaylistAPI:

...

        public List<YouTubePlayList> GetUserPlayLists(string userEmail)
        {
            var playLists = new List<YouTubePlayList>();

            try
            {
                var service = new YouTubeServiceClient();
                service.GetUserPlayListsAsync(userEmail, playLists).Wait();
            }
            catch (AggregateException ex)
            {
                foreach (var e in ex.InnerExceptions)
                {
                    //TODO: Add Logging
                }
            }

            return playLists;
        }


....

此外，我是否需要在"TODO"评论中添加代码或者是可选的？



谢谢提前，

Amitai

besides, Do I need to added code in the 'TODO' comment or that's optional?

Thanks in advance,
Amitai

推荐答案

问候amitaiwe。

Greetings amitaiwe.

回答你的第二个问题，它是可选的。我们的想法是，您可以将任何错误的详细信息写入文件或事件日志，这样如果出现问题，您可以查看它是什么。但是这不是程序运行所必需的。

To answer your second question, it's optional. The idea is that you can write the details of any error to a file or an event log, so that if something goes wrong you can look up what it was. But that is not necessary for the program to run.

要回答第一个问题，您需要实例化该方法所在的类才能调用该方法。为此，您可以将带有命名空间的using语句添加到表单的代码中，或者使用命名空间为类添加前缀。

To answer your first question, you will need to instantiate the class that the method is in to be able to call the method. To do that, you can either add a using statement with the namespace to your form's code, or prefix the class with the namespace.

例如，如果方法是调用的类的一部分MyClass，就像这样......

For example, if the method is part of a class called MyClass, like this...

namespace YouTubePlaylistAPI
{
   public class MyClass
   { 
       // Other code is in here.


       public List<YouTubePlayList> GetUserPlayLists(string userEmail)
        {
            var playLists = new List<YouTubePlayList>();

            try
            {
                var service = new YouTubeServiceClient();
                service.GetUserPlayListsAsync(userEmail, playLists).Wait();
            }
            catch (AggregateException ex)
            {
                foreach (var e in ex.InnerExceptions)
                {
                    //TODO: Add Logging
                }
            }

            return playLists;
        }
   }
}

...你可以这样称呼它。

... You could call it like this.

// Use the correct namespace.
using YouTubePlaylistAPI;

namespace YouTubeTest
{
    public partial class FormGetPlaylist : Form
    {
        // Instantiate the class we want to use.
        MyClass mc = new MyClass();

        public FormGetPlaylist()
        {
            InitializeComponent();
        }

        private void buttonGoclick_Click(object sender, EventArgs e)
        {
            listBoxPlaylists.Items.Clear();

            string userEmail = textBoxUsersName.Text;

            // Use our instance of the class.
            List<YouTubePlayList> = mc.GetUserPlayLists(usermail);

            foreach (var playlist in playlists)
            {
                listBoxPlaylists.Items.Add(playlist);
            }


        }
    }
}

如果您没有为命名空间输入using语句，则可以使用命名空间作为前缀来实例化该类，如下所示。

If you don't put in the using statement for the namespace, you can instantiate the class by using the namespace as a prefix, like so.

        YouTubePlaylistAPI.MyClass mc = new YouTubePlaylist.MyClass();
