CopyAsync(IStorageFolder)	建立 StorageFile 的複本，並將它儲存在指定的 StorageFolder中。
CopyAsync(IStorageFolder, String)	建立 StorageFile的複本、提供指定的檔案名，並將它儲存在指定的 StorageFolder中。
CopyAsync(IStorageFolder, String, NameCollisionOption)	建立 StorageFile的複本、提供指定的檔案名，並將它儲存在指定的 StorageFolder中。 如果具有相同名稱的檔案已存在於指定的資料夾中，方法也會指定該怎麼做。

CopyAsync(IStorageFolder)

建立 StorageFile 的複本，並將它儲存在指定的 StorageFolder中。

public:
 virtual IAsyncOperation<StorageFile ^> ^ CopyAsync(IStorageFolder ^ destinationFolder) = CopyAsync;

/// [Windows.Foundation.Metadata.Overload("CopyOverloadDefaultNameAndOptions")]
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<StorageFile> CopyAsync(IStorageFolder const& destinationFolder);

[Windows.Foundation.Metadata.Overload("CopyOverloadDefaultNameAndOptions")]
[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperation<StorageFile> CopyAsync(IStorageFolder destinationFolder);

function copyAsync(destinationFolder)

Public Function CopyAsync (destinationFolder As IStorageFolder) As IAsyncOperation(Of StorageFile)

參數

destinationFolder

IStorageFolder

要在其中儲存所複製檔案的資料夾。

傳回

IAsyncOperation<StorageFile>

當這個方法成功完成時，它會以 StorageFile 物件的形式傳回復本。
