示例

下面的示例阐释如何创建新的 ColorDialog。此示例要求从一个现有窗体调用该方法，且该窗体上须有一个 TextBox 和 Button。

Private Sub button1_Click(sender As Object, e As System.EventArgs)
    Dim MyDialog As 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) Then
        textBox1.ForeColor =  MyDialog.Color
    End If

End Sub 'button1_Click

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;
 }
    

private:
   void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      ColorDialog^ MyDialog = gcnew 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
