当我创建一个BitmapImage时,Height参数给了我...宽度。 这是我的代码,如果你看到错误,我不能。C#获取BitmapImage高度

private void button_Click(object sender, RoutedEventArgs e) 
    { 
     OpenFileDialog openFileDialog = new OpenFileDialog(); 
     openFileDialog.Filter = "Bitmap files (*.bmp)|*.bmp"; 
     openFileDialog.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Desktop); 
     if (openFileDialog.ShowDialog() == true) 
     { 
      BitmapImage image = new BitmapImage(new Uri(openFileDialog.FileName)); 
      int maxHeight = 100; 
      if(image.Height != maxHeight) 
      { 
       MessageBox.Show("Error with the size"); 
       return; 
      } 
      FileTextBlock.Text = openFileDialog.FileName; 
      ImageWPF.Source = imageEndo; 
     } 
    } 

试图用一个高度为100,宽度为16的bitrmap图像,在image.Height中获得16。

使用PixelHeight代替https://msdn.microsoft.com/en-us/library/system.windows.media.imaging.bitmapsource.pixelheight(v=vs.110).aspx –

感谢兰德随机,我解决了我的问题与PixelHeight而不是高度。
