下圖顯示了我的項目是什麼。選項嚴格時的錯誤
您可以在您的測試需求下面我的項目代碼。
<Window x:Class="MainWindow"

Class MainWindow
Private Sub Button1_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles Button1.Click
Dim myOFD As New Microsoft.Win32.OpenFileDialog
myOFD.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Desktop)
myOFD.Filter = "Image File (*.png)|*.png"
If myOFD.ShowDialog = True Then
Dim myBitmap As New BitmapImage
myBitmap.BeginInit()
myBitmap.UriSource = New Uri(uriString:=myOFD.FileName, UriKind:=UriKind.RelativeOrAbsolute)
myBitmap.EndInit()
myBitmap.Freeze()
Image1.Source = myBitmap
End If
End Sub
Private Sub Button2_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles Button2.Click
Dim myBitmapEncoder As New PngBitmapEncoder()
myBitmapEncoder.Frames.Add(BitmapFrame.Create(Image1.Source))
End Sub
End Class
我有以下錯誤選項時嚴格。
「公共共享功能創建(源作爲System.Windows.Media.Imaging.BitmapSource)作爲System.Windows.Media.Imaging.BitmapFrame」:選項嚴格On不允許從System.Windows.Media.ImageSource隱式轉換'到'System.Windows.Media.Imaging.BitmapSource'。
...
'公共共享功能創建(bitmapStream作爲System.IO.Stream)作爲System.Windows.Media.Imaging.BitmapFrame' 類型的值「System.Windows.Media .ImageSource'不能轉換爲'System.IO.Stream'。
...
'公共共享功能創建(bitmapUri作爲的System.Uri)作爲System.Windows.Media.Imaging.BitmapFrame':類型System.Windows.Media.ImageSource的」價值「不能轉換爲」的System.Uri
那麼錯誤說明了一切。隨着選項Stict開啓,所有幕後演員都必須由您完成! –
這與C#有什麼關係? –
