如何在c#中设置模板

Question

如何通过模板模板在 Sprite 中设置 id

public class templa<T> where T : class , new(){
    public T CreateMe(){
        T temp = new T();
        shortInt si
        si.Set(2, 2);
        //T needs to have id as shortInt else it won't work
        
        temp.id = si; // temp = si// doesn't work either
        return temp;
    }
}
public struct shortInt{
    public short s;
    public int i;
    public void Set(short s, int i){
        this.s = s;
        this.i = i;
    }
}

这里的 Sprite 有 id 这是我试图通过模板更改 id 来实现的目标

public class Sprite{
    public Sprite(){}
    public shortInt id;
    set{
        id = value;
    }
}

我在网上搜索，发现只能用 { get;放; } 我在这里一无所知

使用where(generic type constraint)

这样的代码

 public class Templat<T> where T :
     Sprite, new()  //constraint in here
    {
        public T CreateMe()
        {
            T temp = new T();
            shortInt si = new shortInt();
            si.Set(2, 2);

            temp.id = si;
            return temp;
        }

    }

    public struct shortInt
    {
        public short s;
        public int i;
        public void Set(short s, int i)
        {
            this.s = s;
            this.i = i;
        }
    }

    public class Sprite
    {
        public Sprite() { }
        public shortInt id { get; set; }
    }
