Question

The user right clicks on a file(say on the desktop) and clicks \'copy\' . Now how do I determine in C# if the file copied to the clipboard is an image type ?

Answer 1

You can check it like this (There is no built in way of doing this) Read the file and use it in a Graphics Image Object if it will be image it will work fine else it will Raise an OutOfMemoryException.

here is a sample code:

 bool IsAnImage(string filename)
  {
   try
    {
        Image newImage = Image.FromFile(filename);
    }
    catch (OutOfMemoryException ex)
    {
        // Image.FromFile will throw this if file is invalid.
       return false;
    }
    return true;
  }

It will work for BMP, GIF, JPEG, PNG, TIFF file formats

Update

Here is the code to get the FileName:

IDataObject d = Clipboard.GetDataObject();
if(d.GetDataPresent(DataFormats.FileDrop))
{
    //This line gets all the file paths that were selected in explorer
    string[] files = d.GetData(DataFormats.FileDrop);
    //Get the name of the file. This line only gets the first file name if many file were selected in explorer
    string TheImageFile = files[0];
    //Use above method to check if file is Image file
    if(IsAnImage(TheImageFile))
    {
         //Process file if is an image
    }
    {
         //Process file if not an image
    }
}
