C# 存储文件到系统uri?
我有一个用c#编写的Windows Metro应用程序 以下是我用来从本地音乐库中选取文件的代码:C# 存储文件到系统uri?,c#,windows-8,windows-runtime,storagefile,C#,Windows 8,Windows Runtime,Storagefile,我有一个用c#编写的Windows Metro应用程序 以下是我用来从本地音乐库中选取文件的代码: FileOpenPicker openPicker = new FileOpenPicker(); openPicker.ViewMode = PickerViewMode.Thumbnail; openPicker.SuggestedStartLocation = PickerLocationId.MusicLibrary; openPicker.FileTypeFilter.Add(".mp3
FileOpenPicker openPicker = new FileOpenPicker();
openPicker.ViewMode = PickerViewMode.Thumbnail;
openPicker.SuggestedStartLocation = PickerLocationId.MusicLibrary;
openPicker.FileTypeFilter.Add(".mp3");
openPicker.FileTypeFilter.Add(".wav");
StorageFile file = await openPicker.PickSingleFileAsync();
if (file != null)
{
myMediaElement.Source = file; //error here
}
else
{
//error here
}
它表示,
StorageFile
无法转换为用于更改MediaElement源的System.Uri
。如何使我的文件成为uri链接?似乎Uri(“…”)
只接受文件位置的String
。您必须使用文件流以及SetSource
。发件人:
var file = await openPicker.PickSingleFileAsync();
var stream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read);
myMediaElement.SetSource(stream, file.ContentType);
