C#如何制作泛型类？

public class GenericClass<T>
{
    private T _data;

    public GenericClass(T data)
    {
        _data = data;
    }

    public T GetData()
    {
        return _data;
    }

    public void SetData(T data)
    {
        _data = data;
    }
}

public static void Main(string[] args)
{
    // 创建整数类型的泛型类实例
    GenericClass<int> intGeneric = new GenericClass<int>(5);
    Console.WriteLine("整数类型的数据: " + intGeneric.GetData());

    // 创建字符串类型的泛型类实例
    GenericClass<string> stringGeneric = new GenericClass<string>("Hello, World!");
    Console.WriteLine("字符串类型的数据: " + stringGeneric.GetData());
}
