c# XNA覆盖错误

我得到一个错误，

"错误1 ' gamestatmanagement . gameplayscreen . draw (Microsoft.Xna.Framework.GameTime，':没有找到合适的方法override"

我不知道怎么了。我是一个编程新手，从我的大学课程中得到了一些代码。其余的都是我自己做的。我不知所措，我该如何解决这个问题?

代码
        /// Draws the gameplay screen.
        /// </summary>
        public override void Draw(GameTime gameTime, InputState input)
        {
            // This game has a blue background. Why? Because! Not anymore, haha!
            var colorMatch = new Dictionary<int, Color>();
            colorMatch.Add(1, Color.LightBlue);
            colorMatch.Add(2, Color.CornflowerBlue);
            colorMatch.Add(3, Color.Blue);
            colorMatch.Add(4, Color.White);
            colorMatch.Add(5, Color.LightGreen);
            colorMatch.Add(6, Color.Green);
            colorMatch.Add(7, Color.Purple);
            colorMatch.Add(8, Color.Chocolate);
            colorMatch.Add(9, Color.Crimson);
            colorMatch.Add(10, Color.IndianRed);

            // Draw munchies

            {
                if (munchieAnimationCount[i] == 0)
                {

c# XNA覆盖错误

您只能覆盖在父类中定义的方法。这意味着当你实现一个继承自Game的类时(就像你在编写XNA游戏时所做的那样)，你可以覆盖类Game的draw方法，它具有以下签名:

protected virtual void Draw (
    GameTime gameTime
)

在你的代码中，你试图覆盖一个方法，

protected virtual void Draw (
     GameTime gameTime,
     InputState input
)

在你的超类Game中不存在

(参见Game)。绘制方法。)

尝试删除关键字override。

public void Draw(GameTime gameTime, InputState input)
