Question

我有以下课程......

LetterScore.cs

public class LetterScore {
    public char Letter;
    public int Score;

    public LetterScore(char c = ' ', int score = 0) {
        Letter = c;
        Score = score;
    }

    public override string ToString() => $"LETTER:{Letter}, SCORE:{Score}";
}

LetterPoint.cs

public class LetterPoint {
    public char Letter;
    public Point Position;

    public LetterPoint(char c = ' ', int row = 0, int col = 0) {
        Letter = c;
        Position = new Point(row, col);
    }

    public string PositionToString => $"(X:{Position.X}Y:{Position.Y})";
    public override string ToString() => $"(LETTER:{Letter}, POSITION:{PositionToString})";
}

我可以使用LINQ或通用变量（例如T）将这两个类组合成一个类吗？

我希望这样做，因为可能会有更多的课程我的项目需要改变这些类的格式（例如，每个类都有一个字母和一个对应于某个特定的值情况）

是的，你可以用泛型来做到这一点：

public class Letter<T>
{
    public char Letter {get;set;}
    public T Item {get;set;} /*or make this protected and expose it in your derived class */
}

public class LetterPoint : Letter<Point>
{
    public LetterPoint(char c = ' ', int row = 0, int col = 0)
    {
        Letter = c;
        Item = new Point(row, col);
    }

    public string PositionToString => $"(X:{Item.X}Y:{Item.Y})";
    public override string ToString() => $"(LETTER:{Letter}, POSITION:{PositionToString})";

}

public class LetterScore : Letter<int>
{

    public LetterScore(char c = ' ', int score = 0)
    {
        Letter = c;
        Item = score;
    }

    public override string ToString() => $"LETTER:{Letter}, SCORE:{Item}";
}

是否可以将以下类组合成一个通用类？
