如何访问foreach之外的变量(C#)

using System;

class Program
{
    static void Main()
    {
        int[] numbers = { 1, 2, 3, 4, 5 };
        int total = 0;

        foreach (int number in numbers)
        {
            total += number;
        }

        Console.WriteLine("Total: " + total);
    }
}

using System;

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

class Program
{
    static void Main()
    {
        MyClass[] objects = { new MyClass { MyProperty = 1 }, new MyClass { MyProperty = 2 }, new MyClass { MyProperty = 3 } };
        int total = 0;

        foreach (MyClass obj in objects)
        {
            total += obj.MyProperty;
        }

        Console.WriteLine("Total: " + total);
    }
}
