When using this method, you must dispose of the resulting Hfont using the GDI DeleteObject method to ensure the resources are released.

The following code example creates a Font and then gets a handle to that Font. The example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler.


//Reference the GDI DeleteObject method.
       [System.Runtime.InteropServices.DllImport("GDI32.dll")]
       public static extern bool DeleteObject(IntPtr objectHandle); 

       public void ToHfont_Example(PaintEventArgs e)
       {
           // Create a Font object.
           Font myFont = new Font("Arial", 16);

           // Get a handle to the Font object.
           IntPtr hFont = myFont.ToHfont();

           // Display a message box with the value of hFont.
           MessageBox.Show(hFont.ToString());

           //Dispose of the hFont.
           DeleteObject(hFont);
       }
