在具有多个构造函数的单个 class 中使用一个对象

Question

这是我在其中构建构造函数的 class，我想要多个 "UserKeys" 构造函数，我项目中的每个角色 1 个，但主要的 class 没有仅识别第二个构造函数（如果我有一个带 0 个参数的构造函数，它会识别第一个，但不会识别第二个）

abstract class BaseKeys
{
    public abstract bool LeftPressed();
    public abstract bool RightPressed();
    public abstract bool UpPressed();
    public abstract bool DownPressed();
    public abstract bool high_hitPressed();
    public abstract bool rope_jumpPressed();
    public abstract bool runRightPressed();
    public override bool leftRightPressed();
}

class UserKeys : BaseKeys
{
    #region data
    Keys left, right, up, down, walk;
    Keys combo, high_hit;
    #endregion

    #region ctor
    public UserKeys(Keys left, Keys right,
                    Keys up, Keys down, Keys high_hit)
    {
        this.left = left;
        this.right = right;
        this.up = up;
        this.down = down;
        this.high_hit = high_hit;
    }

    public UserKeys(Keys right, Keys left, 
                    Keys down, Keys walk, Keys high_hit)
    {
        this.left = left;
        this.right = right;
        this.down = down;
        this.high_hit = high_hit;
        this.walk = walk;
    }
}

两个构造函数具有相同的参数，这是行不通的。只有他们的名字不同。您需要让它们与众不同：

public UserKeys(Keys left, Keys right,
                Keys up, Keys down, 
                Keys high_hit)
{
    this.left = left;
    this.right = right;
    this.up = up;
    this.down = down;
    this.high_hit = high_hit;
}

public UserKeys(Keys left, Keys right, 
                Keys up, Keys down, 
                Keys high_hit, Keys walk)
{
    this.left = left;
    this.right = right;
    this.up = up;
    this.down = down;
    this.high_hit = high_hit;
    this.walk = walk;
}

我已将 Keys up 添加到第二个并使用与第一个相同的顺序（否则非常混乱且容易出错）。如果你不知道 Keys up 通过 Keys.None.
