Google API DotNet Youtube播放列表失败，无播放列表ID

Question

谢谢，我非常感谢您的帮助！

我想让.NET的Google API客户端正常工作，但我不知道如何做甚至简单的事情。我的目标是建立一个网页，在顶部加载一个YouTube播放列表播放器，并只列出其下方其他曲目的相关信息。

你能帮我解决一下让客户端运行的第一个问题吗？

我有一个.NET 4.0网站实例，我已经通过nuget软件包管理器安装了DotNet Google API。我认为问题在于我无法弄清楚如何将PlaylistID传递给客户端请求。在下面的代码中，我可以指定PlaylistID？

Imports Google.Apis.YouTube.v3 
Imports Google.Apis.YouTube.v3.Data 

Dim Initialiser As New Google.Apis.Services.BaseClientService.Initializer() 
Initialiser.ApiKey = "My Server API Key" 
Dim Service As YouTubeService = New YouTubeService(Initialiser) 
Dim Result As PlaylistItemListResponse 
Result = Service.PlaylistItems().List("snippet").Execute() 
If Not Result.Items Is Nothing Then 
    Dim XPathDocument As System.Xml.XPath.XPathDocument = GenerateXPathDocument(Result.Items) 
    SamplerXml.XPathNavigator = XPathDocument.CreateNavigator 
End If 

错误输出是：

谢谢您的帮助和您的时间！

答案结果很简单。所以我不得不创建列表请求，然后设置播放列表ID，然后执行请求。有时我可以真的很慢...

我希望这可以帮助别人！
