c# - 如何创建颜色选择器？

Question

这是我到目前为止的代码:

private void btnColour_Click(object sender, EventArgs e)
    {
        //show the colour dialog and check that user clicked ok
        if (clrDialog.ShowDialog() == DialogResult.OK)
        {
            //save the colour that the user chose
            c = clrDialog.Color;
        }
    }

Color c = Color.Black;

这不是应该有效吗？也许我选择了错误的事件？

您应该在事件处理程序中而不是外部创建对话框，尝试如下操作:

private void btnColour_Click(object sender, EventArgs e)
{
    ColorDialog clrDialog = new ColorDialog();

    //show the colour dialog and check that user clicked ok
    if (clrDialog.ShowDialog() == DialogResult.OK)
    {
        //save the colour that the user chose
        c = clrDialog.Color;
    }
}

Color c = Color.Black;
