如何确保List <T> .Contains(T)与我的自定义类一起使用？

public class CustomClass
{
    public int Property1 { get; set; }
    public string Property2 { get; set; }

    public override bool Equals(object obj)
    {
        if (obj is CustomClass other)
        {
            return this.Property1 == other.Property1 && this.Property2 == other.Property2;
        }
        return false;
    }

    public override int GetHashCode()
    {
        return HashCode.Combine(this.Property1, this.Property2);
    }
}

var list = new List<CustomClass>();

// 添加一些对象到列表中
list.Add(new CustomClass { Property1 = 1, Property2 = "A" });
list.Add(new CustomClass { Property1 = 2, Property2 = "B" });
list.Add(new CustomClass { Property1 = 3, Property2 = "C" });

// 检查列表中是否包含特定对象
var objToCheck = new CustomClass { Property1 = 2, Property2 = "B" };
bool contains = list.Contains(objToCheck);
