C#对象列表,如何获取属性的总和

using System;
using System.Collections.Generic;

public class MyClass
{
    public int MyProperty { get; set; }
}

public class Program
{
    public static void Main()
    {
        List<MyClass> myList = new List<MyClass>();

        // 添加对象到列表
        myList.Add(new MyClass { MyProperty = 10 });
        myList.Add(new MyClass { MyProperty = 20 });
        myList.Add(new MyClass { MyProperty = 30 });

        int sum = 0;
        foreach (var obj in myList)
        {
            // 累加属性值
            sum += obj.MyProperty;
        }

        Console.WriteLine("属性的总和为：" + sum);
    }
}
