The following code example uses the ColorDialog implementation of CommonDialog and illustrates creating and showing a dialog box. This example requires that the method is called from within an existing form, which has a TextBox and Button placed on it.

private void button1_Click(object sender, System.EventArgs e)
 {
    ColorDialog MyDialog = new ColorDialog();
    // Keeps the user from selecting a custom color.
    MyDialog.AllowFullOpen = false ;
    // Allows the user to get help. (The default is false.)
    MyDialog.ShowHelp = true ;
    // Sets the initial color select to the current text color.
    MyDialog.Color = textBox1.ForeColor ;
    
    // Update the text box color if the user clicks OK 
    if (MyDialog.ShowDialog() == DialogResult.OK)
        textBox1.ForeColor =  MyDialog.Color;
 }
    

protected void button1_Click(Object sender, System.EventArgs e)
{
    ColorDialog myDialog = new ColorDialog();
    // Keeps the user from selecting a custom color.
    myDialog.set_AllowFullOpen(false);
    // Allows the user to get help. (The default is false.)
    myDialog.set_ShowHelp(true);
    // Sets the initial color select to the current text color.
    myDialog.set_Color(textBox1.get_ForeColor());
    // Update the text box color if the user clicks OK 
    if (myDialog.ShowDialog().Equals(get_DialogResult().OK)) {
        textBox1.set_ForeColor(myDialog.get_Color());
    }
} //button1_Click
