If you have set the BackgroundImage property using the Winforms designer, Visual Studio has generated in the .Designer.cs file the following line for you:

this.button1.BackgroundImage = global::WindowsFormsApplication5.Properties.Resources.my_image_name;

As you can see, it's affecting a value of type System.Drawing.Bitmap to a property of type System.Drawing.Image. The only information you have here is the image itself.

If you added the image by yourself:

string resourceKey = "my_image_name";
this.button1.BackgroundImage = (System.Drawing.Image)Properties.Resources.ResourceManager.GetObject(resourceKey);

then you already have the name of your resource...

If it doesn't answer your question, then please make it clearer.

You cannot retrieve the name of the image.

What you can do is when you set the image: store the name of the image in the Tag property of the Button.

You can then check the Tag property as long as you keep it in sync with the image.

Even nicer would be to sub-class the Button and add a property that stores the name.
