First and foremost, I apologize for my grammatical errors; my first language is Persian (Iran).
I have custom Context Menu and MenuItem.
I want to set the MenuItem icon source from the binary image.
These are my codes:
XAML:

C#:
public AuthenticationWindow()
{
InitializeComponent();
ContextMenu CustomContextMenu = this.Resources["CustomContextMenu"] as ContextMenu;
MenuItem CopyMenuItem = CustomContextMenu.Items[0] as MenuItem;
MenuItem CutMenuItem = CustomContextMenu.Items[1] as MenuItem;
MenuItem PasteMenuItem = CustomContextMenu.Items[2] as MenuItem;
BitmapImage[] bmp = new BitmapImage[8];
bmp[0] = GetImageFromBytes(System.IO.File.ReadAllBytes(System.Windows.Forms.Application.StartupPath + @"\Images\Add.bin"));
bmp[1] = GetImageFromBytes(System.IO.File.ReadAllBytes(System.Windows.Forms.Application.StartupPath + @"\Images\Close.bin"));
bmp[2] = GetImageFromBytes(System.IO.File.ReadAllBytes(System.Windows.Forms.Application.StartupPath + @"\Images\Copy.bin"));
bmp[3] = GetImageFromBytes(System.IO.File.ReadAllBytes(System.Windows.Forms.Application.StartupPath + @"\Images\Cut.bin"));
bmp[4] = GetImageFromBytes(System.IO.File.ReadAllBytes(System.Windows.Forms.Application.StartupPath + @"\Images\Delete.bin"));
bmp[5] = GetImageFromBytes(System.IO.File.ReadAllBytes(System.Windows.Forms.Application.StartupPath + @"\Images\Edit.bin"));
bmp[6] = GetImageFromBytes(System.IO.File.ReadAllBytes(System.Windows.Forms.Application.StartupPath + @"\Images\Minimize.bin"));
bmp[7] = GetImageFromBytes(System.IO.File.ReadAllBytes(System.Windows.Forms.Application.StartupPath + @"\Images\Paste.bin"));
Add_Button.Content = bmp[0];
CloseIconImage.Source = bmp[1];
CopyMenuItem.Icon = bmp[2];
CutMenuItem.Icon = bmp[3];
Delete_Button.Content = bmp[4];
Edit_Button.Content = bmp[5];
MinimizeIconImage.Source = bmp[6];
PasteMenuItem.Icon = bmp[7];
}
I use the following method to convert a binary image to a bitmap image ( this method works properly in other cases ):
private BitmapImage GetImageFromBytes(byte[] bytes)
{
System.IO.MemoryStream Stream = new System.IO.MemoryStream();
Stream.Write(bytes, 0, bytes.Length);
Stream.Position = 0;
System.Drawing.Image img = System.Drawing.Image.FromStream(Stream);
BitmapImage bitImage = new BitmapImage();
bitImage.BeginInit();
System.IO.MemoryStream MS = new System.IO.MemoryStream();
img.Save(MS, System.Drawing.Imaging.ImageFormat.Png);
MS.Seek(0, System.IO.SeekOrigin.Begin);
bitImage.StreamSource = MS;
bitImage.EndInit();
return bitImage;
}
But the output is as follows:
I think the problem is with the XAML code.
Thanks
