如何在构建时将文件从Visual Studio项目复制到UWP应用程序的LocalFolder

首先，将.csv文件添加到资产文件夹，并将构建操作设置为Content。

之后，您可以在运行时使用以下代码片段将文件从资产手动复制到本地文件夹。

var file = await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///Assets/HighScore.csv"));
 if (file != null)
 {
     // Copy .csv file to LocalFolder so we can read / write to it.
     // No CollisionOption will default to Fail if file already exists,
     // to copy every time the code is run, add NameCollisionOption.ReplaceExisting
     await file.CopyAsync(ApplicationData.Current.LocalFolder);

     // Get path of newly created file
     String newFile = ApplicationData.Current.LocalFolder.Path + "/HighScore.csv";
 }
