如何使用颜色类型数组的值来为形状着色？ [英] How to use the values of color type array to color a shape?

问题描述

我有一个颜色类型数组，使得：







colorSet [0] =颜色.DodgerBlue;

colorSet [1] = Color.YellowGreen;

colorSet [2] = Color.Crimson;

colorSet [3] = Color.HotPink;

colorSet [4] = Color.MediumPurple;

colorSet [5] = Color.MediumSeaGreen;

colorSet [6] = Color.MediumVioletRed;

colorSet [7] = Color.PaleVioletRed;

colorSet [8] = Color.Plum;

colorSet [9 ] = Color.SlateBlue;







i想用Color [5]代替Red in以下声明：









DrawEllipse（Pens.Red，50 *我，50 * j，8,8）;



怎么办?????????



我尝试过：



i尝试过：




DrawEllipse（Pens.colorSet [5]，50 * i，50 * j，8,8）;

i have a color type array such that:



colorSet[0] = Color.DodgerBlue;
colorSet[1] = Color.YellowGreen;
colorSet[2] = Color.Crimson;
colorSet[3] = Color.HotPink;
colorSet[4] = Color.MediumPurple;
colorSet[5] = Color.MediumSeaGreen;
colorSet[6] = Color.MediumVioletRed;
colorSet[7] = Color.PaleVioletRed;
colorSet[8] = Color.Plum;
colorSet[9] = Color.SlateBlue;



i want to use Color[5] in place of Red in following statement:




DrawEllipse(Pens.Red, 50 * i, 50 * j, 8, 8);

what to do?????????

What I have tried:

i have tried :


DrawEllipse(Pens.colorSet[5], 50 * i, 50 * j, 8, 8);

推荐答案

这比你认为：颜色和笔是不一样的，而笔是稀缺资源，所以当你使用自己的时候，你有责任在你完成后正确处理它。

That's more complex than you think: a Color and a Pen aren't the same thing, and a Pen is a scarce resource, so when you use your own, you are responsible for Disposing it correctly when you are finished.

private void myPanel_Paint(object sender, PaintEventArgs e)
    {
    using (Pen p = new Pen(colorSet[5]))
        {
        e.Graphics.DrawEllipse(p, 50, 50, 8, 8);
        }
    }
