介绍

泛型类型是类型的模板

using System;

// 定义一个泛型类
public class MyGenericClass<T>
{
    public T Value { get; set; }

    public MyGenericClass(T value)
    {
        Value = value;
    }
}

// 定义一个泛型接口
public interface IMyGenericInterface<T>
{
    T GetValue();
}

// 实现泛型接口
public class MyImplementation : IMyGenericInterface<int>
{
    private int data;

    public MyImplementation(int value)
    {
        data = value;
    }

    public int GetValue()
    {
        return data;
    }
}

class Program
{
    static void Main()
    {
        // 使用泛型类
        MyGenericClass<int> intInstance = new MyGenericClass<int>(42);
        MyGenericClass<string> stringInstance = new MyGenericClass<string>("Hello, World!");

        Console.WriteLine($"Integer Value: {intInstance.Value}");
        Console.WriteLine($"String Value: {stringInstance.Value}");

        // 使用泛型接口
        MyImplementation impl = new MyImplementation(100);
        int valueFromInterface = impl.GetValue();
        Console.WriteLine($"Value from interface: {valueFromInterface}");
    }
}
