C# 获取“无法隐式转换类型”错误，但无法找出原因

我的Razor pages项目中有两个文件。一个是AllTracks.htmlcs.cs和AllAlbums.htmlcs.cs

除了一些小的差异外，它们共享的代码基本相同，尽管在我的AllTracks.html.cs页面上，我发现以下错误：

Pages\AllTracks.htmlcs.cs(25,26): error CS0029: Cannot implicitly convert type 'System.Collections.Generic.List<namespaceHere.Album>' to 'System.Collections.Generic.List<namespaceHere.Tracks>'

我试着调试这个，我试着改变变量名，四处看看，但我一辈子都不明白为什么我会被抛出这个错误，有人能看看我的代码，让我知道为什么会发生这种情况吗

您好@DonnieBerry，asp.net-mvc是与asp.net-core-mvc不同的框架。entity framework和entity-framework-core也是如此。异常消息非常清楚。在AllTracksModel类的OnGet方法中，您应该查询Track，但您正在查询Album。希望这个提示能帮助你解决这个问题。谢谢。你指的是哪一行？我看不到我在AllTracksModel类上查询“Album”的位置。嗨@Donnie，检查AllTracksModel类的OnGet方法。您的LINQ查询正在使用基于您问题中的源代码的相册。您好，对不起，我是Razor pages的新手。我认为，当我想在这个特定用例中使用相册表时，通过使用_Context.tracks可以访问tracks表。这不对吗？
