通用对象池(Generic object pool)

 是否有可能创建一个通用对象池，在其中创建新的对象？ 另外如果这个对象创建可以接收参数将会很好。 
 
    public interface IPoolable
    {
        void Dispose();
    }


    public class ObjectPool<T> where T : IPoolable
    {
        private List<T> pool;

        public T Get()
        {
            if(pool.count > 0)
            {
                return pool.Pop();
            }
            else
            {
                return new T(); //  <- How to do this properly?
            }
        }
    }

    public class SomeClass : IPoolable
    {
        int id;

        public SomeClass(int id)
        {
            this.id = id;
        }

        public void Dispose()
        {

        }
    }

    public class OtherClass : IPoolable
    {
        string name;
        int id;

        public OtherClass(string name, int id)
        {
            this.name = name;
            this.id = id;
        }

        public void Dispose()
        {

        }
    }
 
 如果它可以接收参数，它可以像这样使用。 
 
SomeClass a = myPool.Get(2);
OtherClass b = myOtherPool.Get("foo", 4);
 
 或者如果参数不可行，这也可以。 
 
SomeClass a = myPool.Get();
a.id = 2;
OtherClass b = myOtherPool.Get();
b.name = "foo";
b.id = 4;

Is it possible to create a generic object pool that creates new objects inside it? Plus it would be nice if this object creation could receive parameters.
 
    public interface IPoolable
    {
        void Dispose();
    }


    public class ObjectPool<T> where T : IPoolable
    {
        private List<T> pool;

        public T Get()
        {
            if(pool.count > 0)
            {
                return pool.Pop();
            }
            else
            {
                return new T(); //  <- How to do this properly?
            }
        }
    }

    public class SomeClass : IPoolable
    {
        int id;

        public SomeClass(int id)
        {
            this.id = id;
        }

        public void Dispose()
        {

        }
    }

    public class OtherClass : IPoolable
    {
        string name;
        int id;

        public OtherClass(string name, int id)
        {
            this.name = name;
            this.id = id;
        }

        public void Dispose()
        {

        }
    }
 
In a way that it can be used like this if it could receive parameters.
 
SomeClass a = myPool.Get(2);
OtherClass b = myOtherPool.Get("foo", 4);
 
Or this would also be fine if parameters were not possible.
 
SomeClass a = myPool.Get();
a.id = 2;
OtherClass b = myOtherPool.Get();
b.name = "foo";
b.id = 4;
