Expression Tree使うとこういうのが簡単に作れる
static class GenericCalculator<T> {
private static readonly Func<T, T, T> add;
static GenericCalculator() {
var left = Expression.Parameter(typeof(T), "left");
var right = Expression.Parameter(typeof(T), "left");
add = Expression.Lambda<Func<T, T, T>>(Expression.Add(left, right)).Compile();
}
public static T Add(T left, T right) { return add(left, right); }
//他の演算子も同様
}
