c#对象集合的比较

//如果要比较序列中对象的实际数据而不是仅仅比较它们的引用，则必须在类中实现IEqualityComparer<T> 泛型接口
public class People:IEquatable<People> 
{
    public string Name { get; set; }
    public int Age { get; set; }
    public bool Equals(People other)
    {
        if (other is null)
            return false;
 
        return this.Name == other.Name && this.Age == other.Age;
    }     
}
