VB.net - Openfilepicker 在 windows 移动 10 应用程序中不起作用
VB.net - Openfilepicker does not work in windows mobile 10 app
我正在开发 Windows 10 UWP 和这段代码:
Dim wopk As FileOpenPicker = New FileOpenPicker
With wopk
.ViewMode = PickerViewMode.List
.SuggestedStartLocation = PickerLocationId.DocumentsLibrary
.FileTypeFilter.Add(".txt")
dim wfile = Await .PickSingleFileAsync()
End with
我的 Lumia 535(Windows 移动 10)崩溃,没有错误消息(调试和运行时模式)。
出现启动画面但仍然挂起。
在桌面上一切正常。
在包清单声明中,我为文件 Open/Save Picker 定义了“.txt”扩展名。
该项目的目标 "Windows 10" 和版本 "Build 10586"。
这是我很快写的东西,它应该允许你访问openfilepicker
它不完整,但它应该引导你朝着正确的方向前进。
Imports Windows.Storage.Pickers
Public NotInheritable Class MainPage
Inherits Page
Private Async Sub button_Click(sender As Object, e As RoutedEventArgs) Handles button.Click
Dim openfilepicker = New FileOpenPicker
openfilepicker.SuggestedStartLocation = PickerLocationId.DocumentsLibrary
openfilepicker.FileTypeFilter.Add(".txt")
openfilepicker.CommitButtonText = "Open"
Dim Textfile = Await openfilepicker.PickSingleFileAsync()
If Textfile IsNot Nothing Then
Dim SelectedTextFile = Await Textfile.OpenAsync(Windows.Storage.FileAccessMode.ReadWrite)
'Write your code here using SelectedTextFile as the source for the async.
End If
End Sub
End Class
如果您有任何问题,我会尽力帮助您,但是根据您的问题所述,这应该绰绰有余。
编码愉快!
