C#中泛型类的算术运算符重载

public class GenericNumber<T> where T : struct, IComparable<T>
{
    public T Value { get; set; }

    public GenericNumber(T value)
    {
        Value = value;
    }

    public static GenericNumber<T> operator +(GenericNumber<T> a, GenericNumber<T> b)
    {
        dynamic result = a.Value + b.Value;
        return new GenericNumber<T>(result);
    }

    public static GenericNumber<T> operator -(GenericNumber<T> a, GenericNumber<T> b)
    {
        dynamic result = a.Value - b.Value;
        return new GenericNumber<T>(result);
    }

    // 其他算术运算符重载
}

var num1 = new GenericNumber<int>(5);
var num2 = new GenericNumber<int>(3);
var result = num1 + num2;
Console.WriteLine(result.Value); // 输出 8
