C# - 如何在列表中添加所有 system.drawing.color 项目？

Question

我正在尝试用 system.drwaing.color 项目填充我的列表以选择随机颜色并将其设置为 backColor。

这是我的代码:

    List<Color> myList = new List<Color>();
    //rc.Add(Color.Chartreuse);
    //rc.Add(Color.DeepSkyBlue);
    //rc.Add(Color.MediumPurple);
    foreach (Color clr in System.Drawing.Color)
    {
      //error  
    }
    Random random = new Random();
    Color color = myList[random.Next(myList.Count - 1)];
    this.BackColor = color;

错误: “System.Drawing.Color”是一种“类型”，在给定上下文中无效

谁能帮帮我？

public static List<Color> ColorStructToList()
{
    return typeof(Color).GetProperties(BindingFlags.Static | BindingFlags.DeclaredOnly | BindingFlags.Public)
                        .Select(c => (Color)c.GetValue(null, null))
                        .ToList();
}

List<Color> colorList = ColorStructToList();

private void randomBackgroundColorButton_Click(object sender, EventArgs e)
{
    List<Color> myList = ColorStructToList();
    Random random = new Random();
    Color color = myList[random.Next(myList.Count - 1)];
    this.BackColor = color;
}

public static List<Color> ColorStructToList()
{
    return typeof(Color).GetProperties(BindingFlags.Static | BindingFlags.DeclaredOnly | BindingFlags.Public)
                        .Select(c => (Color)c.GetValue(null, null))
                        .ToList();
}
