根據指定使用者檔案系統中的絕對路徑取得 StorageFolder

public:
 static IAsyncOperation<StorageFolder ^> ^ GetFolderFromPathForUserAsync(User ^ user, Platform::String ^ path);
/// [Windows.Foundation.Metadata.RemoteAsync]
 static IAsyncOperation<StorageFolder> GetFolderFromPathForUserAsync(User const& user, winrt::hstring const& path);
[Windows.Foundation.Metadata.RemoteAsync]
public static IAsyncOperation<StorageFolder> GetFolderFromPathForUserAsync(User user, string path);
function getFolderFromPathForUserAsync(user, path)
Public Shared Function GetFolderFromPathForUserAsync (user As User, path As String) As IAsyncOperation(Of StorageFolder)

async Task<StorageFolder> GetStorageFolderAsync(User user, string path) {

    // or permissions were changed so that the     
    // app no longer has access to the path.     
    try     
    {         
        return await StorageFolder.GetFolderFromPathForUserAsync(user, path);     
    }     
    catch( System.IO.IOException ex )    
    {         
        // File, or path not found I/O Exceptions can happen  
        // notify user or implement fallback, etc...         
        string message = ex.Message;         
        return null;     
    }     
    catch(System.UnauthorizedAccessException ex)     
    {
