如何在 Unity Hololens 中将文件从一个目录移动到另一个目录

Question

here is picture of the code

I am trying to use windows.storage namespace and trying to drop a file in Streaming asset in unity.

Answer 1

The Unity StreamingAssets folder is read-only and used to store Assets. For specific instructions, please see the Unity official doc: Application.StreamingAssetsPath .

Therefore, I suggest you save the file in the Application.persistentDataPath and note that source files have read and write permissions.

To move the file from the objects3D folder to the persistentDataPath folder, you can try the following code:

#if ENABLE_WINMD_SUPPORT
        var objectPath = KnownFolders.Objects3D.Path;
        string path = Path.Combine(objectPath, "MyFile.txt");
        string targetPath = Path.Combine(Application.persistentDataPath, "MyFile.txt");
        using (TextWriter writer = File.CreateText(path))
        {
            writer.WriteLine("test");
        }
        File.Move( path, targetPath);
#endif
