An ImageEditor is a UITypeEditor that provides a user interface for the user to select an image for a property. When the user starts the editor, it displays an Open File dialog box that enables the user to navigate to a directory and select a file. The file list is initially filtered by the default file name extensions for the editor.

The following code example uses an EditorAttribute to associate the ImageEditor with a property.

[EditorAttribute(typeof(System.Drawing.Design.ImageEditor), typeof(System.Drawing.Design.UITypeEditor))]
public Image testImage
{
    get
    {
        return testImg;
    }
    set
    {
        testImg = value;
    }
}
private Image testImg;
