• ColorDialog: Double click on Choose Color  button and write the code.

private void btnColorDialog_Click(object sender, EventArgs e)

     colorDialog1.ShowDialog();

     lblColor1.BackColor = colorDialog1.Color;

}

Click over the button Choose Color and a new windows tab will appear to choose the colors:

Select the color and click OK. Color of label1 changes to red.   

                 

• FontDialog: Double click on the button Font Dialog and write the code.

private void btnFontDialog_Click(object sender, EventArgs e)

{

    fontDialog1.ShowDialog();

    Font font = fontDialog1.Font;

}
