C# 泛型类(函数)的实例化小例子

    public T MyElement { get; set; }
}

public T ReturnElement<T>()
{
    throw new NotImplementedException();
}

public class MyClass<T> where T: new()

{
    return new T();
}

public T ReturnElement<T>()
    where T : ICollection<int>, new()

}

public T ReturnElement<T, S>()
    where T : ICollection<S>, new()
