它没有执行 else if(i==1) 中的代码，为什么会这样？

Question

它只执行 if(i==0) 内部的代码并忽略 if(i==1) 内部的代码 还有 if(i==2) 但由于 [=13 我删除了=] 限制是我的新手，但如果我能弄清楚为什么它不执行第一个 else if 语句中的代码，我也许可以同时修复这两个问题

 string[][] friendFamily = new string[][]
        {
            new string[]{"khzix","rengar","shaco" },
            new string[]{"jhin","tf","karma" },
            new string[]{"qiyanna","braum","thresh" }
        };
        for (int i = 0; i < friendFamily.Length; i++)
        {
            if (i == 0)
            {
                for (int x = 0; x < friendFamily[i].Length; x++)
                {
                    for (int j = 0; j < friendFamily.Length; j++)
                    {
                        if (j == 1 || j == 2)
                        {
                            for (int k = 0; k < friendFamily.Length; k++)
                            {
                                Console.WriteLine("hey {0} this is {1}.", friendFamily[i][x], friendFamily[j][k]);
                            }
                        }

                    }
                }
            }
            else if (i == 1)
            {
                for (int x = 0; x < friendFamily[i].Length; x++)
                {
                    for (int j = 0; j < friendFamily.Length; j++)
                    {
                        if (j == 0 || j == 2)
                        {
                            for (int k = 0; k < friendFamily.Length; k++)
                            {
                                Console.WriteLine("hey {0} this is {1}.", friendFamily[i][x], friendFamily[j][k]);
                            }
                        }

                    }
                }
            }

我可以看到你的代码工作正常，所有条件都满足。实际上，阅读您的代码我感到很痛苦。尝试了解我在这里所做的，这正是您所需要的：

using System;
using System.Linq;

string[][] friendFamilies = new string[][]
{
    new string[] { "khzix","rengar","shaco" },
    new string[] { "jhin","tf","karma" },
    new string[] { "qiyanna","braum","thresh" }
};

var allFriends = friendFamilies.SelectMany(x => x);

foreach (var friendToGreet in allFriends)
{
    foreach (var friendWhoGreet in allFriends.Where(x => x != friendToGreet))
    {
        Console.WriteLine($"Hey {friendToGreet} this is {friendWhoGreet}.");
    }
}
