public:
 static IAsyncAction ^ WriteTextAsync(IStorageFile ^ file, Platform::String ^ contents);

/// [Windows.Foundation.Metadata.Overload("WriteTextAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
 static IAsyncAction WriteTextAsync(IStorageFile const& file, winrt::hstring const& contents);

[Windows.Foundation.Metadata.Overload("WriteTextAsync")]
[Windows.Foundation.Metadata.RemoteAsync]
public static IAsyncAction WriteTextAsync(IStorageFile file, string contents);

function writeTextAsync(file, contents)

Public Shared Function WriteTextAsync (file As IStorageFile, contents As String) As IAsyncAction

参数

file

IStorageFile

写入文本的文件。
