Check the Picture box value is null or not

Question

I have developed a visual C# windows form application using Visual Studio IDE.

My problem is how to check if the user has selected an image or not.

I roughly check the Image like a String, Integer objects but it does not work

if(myPictureBox.Image == NULL){
    //The Image is Null
}

Answer 1

You can do a check like this

bool isNullOrEmpty = myPictureBox == null || myPictureBox.Image == null;

Or you can create your own extension method

public static bool IsNullOrEmpty(this PictureBox pb)
{
    return pb == null || pb.Image == null;
}
