c# - T Get(int id) 和 T Get(int id) 的区别

Question

谁能告诉我这两者的区别

public T Get<T>(int id)

和

public T Get(int id)

Answer 1

比较:

class First
{
    public T Get<T>(int id) // T is declared in the method scope
    {
    }
}

和

class Second<T>
{
    public T Get(int id) // T is declared in the class scope
    {
    }
}

还有第三种情况:

class Third<U>
{
    public T Get<T>(int id) // T is declared in the method scope when class scope has another generic argument declared
    {
    }
}
