使用FileSavePicker保存文件时不提示 [英] using FileSavePicker to save files without prompting

问题描述

我开发利用中，我要救它已经完成录制后自动音频C＃中的Windows 8应用。我用FileSavePicker，每次它会打开一个文件保存窗口。不过，我想它没有及时出现。我已输入的文件名，并在FileSavePicker对象的编码。剩下的唯一的事就是静静地保存它。请帮助。

I am developing a Windows 8 app using C# in which I have to save an audio automatically after it has finished recording. I used FileSavePicker and everytime it opens a file save window. However, I want it to happen without the prompt. I have already entered the file name and the encoding in the FileSavePicker object. The only thing remaining is saving it quietly. Please Help.

感谢。

推荐答案

我找到了答案由使用 CreateFileAsync

保存（下FileSavePicker）常用的语法是：

The usual syntax for saving (under FileSavePicker) was:

VAR媒体文件=等待_fileSavePicker.PickSaveFileAsync（）;

如果我取代了它：

StorageFile媒体文件=等待Windows.Storage.KnownFolders.MusicLibrary.CreateFileAsync（file1.mp3，Windows.Storage.CreationCollisionOption.ReplaceExisting）;

问题解决了！我也不得不在应用功能添加的音乐库。

The problem was solved! I also had to add music library in the app capabilities.
