所以我有这段代码可以正常工作,但是对于我的任务,教授希望代码能够使用foreach语句。我能让它工作的唯一方法是使用for循环。任何人都知道如何将for循环转换为foreach语句?
这是代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace CheckZips.cs
{
class Program
{
static void Main(string[] args)
{
int[] zips = new int[10] { 07950, 07840, 07828, 07836, 07928, 07869, 07849, 07852, 07960, 07876 };
int correctZipCode;
int input;
Console.WriteLine("Enter a zip code.");
input = int.Parse(Console.ReadLine());
correctZipCode = Convert.ToInt32(input);
bool found = false;
for (int i = 0; i < zips.Length; ++i)
{
if(correctZipCode == zips[i])
{
found = true;
break;
}
}
if (found)
{
Console.WriteLine("We deliver to that zip code.");
}
else
{
Console.WriteLine("We do not deliver to that zip code.");
}
}
}
}

foreach
可以像这样实现:
foreach (int zip in zips)
{
if (zip == correctZipCode)
{
found = true;
break;
}
}

为什么你不使用LinQ?
var result = zips.Any(x=>x==correctZipCode);
