Add Bitmap without System.InvalidCastException in System.Drawing.dll

See more:

C#2.0

Hi,

i run the following lines of code on a Mobile Device with CE6.0

The Bitmap is shown proper in the Picturebox.
I tried also jpg and png Format with same Result.

The Debugger stops only at the Exception if i activate.
Debugging->Common Language Runtime-> System -> System.InvalidCastException
Without this it will Show it only as Exception (first Chance) in the Output window and the code runs like expected.


Does anybody know how to prevent against this Exception or how to find the reason for it?

try
{
  System.Windows.Forms.PictureBox picturebox = new System.Windows.Forms.PictureBox();
 
  // this line causes the InvalidCastExeption
  // the Bitmap is available and shown proper in the Picturebox.
  // the Debugger stop only in this line if i activate
  // Debugging->Common Language Runtime-> System -> System.InvalidCastException
  // but it jumps over the two catch blocks
  picturebox.Image = new System.Drawing.Bitmap("Bitmap.bmp");
 
  this.Form1.Controls.Add(picturebox);
}
catch (System.InvalidCastException ice)
{
  System.Console.WriteLine(ice.Message);
}
catch (System.Exception ex)
{
  System.Console.WriteLine(ex.Message);
}

thank's
