从数组中删除数据时遇到问题

Question

我在搜索“销售代表姓名”的数组然后删除姓名、销售和佣金时遇到问题。

static void RemoveSale(string[] sellerNames, double[] sellerSales, double[] sellerCommision, ref int sellerCount)
    {
        int index;
        string salesRep;
        try
        {
            if (sellerCount > 0)
            {
                salesRep = GetValidName("Enter the sales rep to delete");
                index = SearchSeller(sellerNames, sellerCount);
                if (index == -1)
                {
                    Console.WriteLine("that sales rep is not on the team");
                }
                else
                {
                    sellerSales[index] = sellerSales[sellerCount - 1];
                    sellerNames[index] = sellerNames[sellerCount - 1];
                    sellerCommision[index] = sellerCommision[sellerCount - 1];
                    Console.WriteLine("Sales rep {0} has been deleted.", sellerNames);
                    sellerCount--;
                }
            }
            else
            {
                Console.WriteLine("there are no sales reps to delete");
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
            Console.ReadLine();
        }
    }


    static int SearchSeller(string[] sellerNames, int sellerCount)
    {
        try
        {
            int index = 0;
            bool found = false;
                            while (!found && index < sellerCount)
            {
                if (sellerNames[sellerCount] == sellerNames[index])
                    found = true;
                else
                    index++;
            }
            if (!found)
                index = -1;
            return index;
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
            Console.ReadLine();
        return 0;
        }

    }

预期结果是删除名称、数据，并确认 SellerName{0} 已被删除。

实际结果是什么都没有被移除，并且没有确认被移除的卖家

您没有将salesRep 对象传递给搜索功能。假设您可以更改搜索功能的签名，请尝试以下操作：

// Pass the name of the sales rep
static int SearchSeller(string[] sellerNames, int sellerCount, string salesRep)
    {
        try
        {
            int index = 0;
            bool found = false;
                            while (!found && index < sellerCount)
            {
                // compare the current name in array with the passed name
                if (salesRep == sellerNames[index])
                    found = true;
                else
                    index++;
            }
            if (!found)
                index = -1;
            return index;
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
            Console.ReadLine();
        return 0;
        }

调试通常应该是检查容易出错的第一步。

更好的搜索选择是使用 c# 函数Find

Array.Find(sellerNames, salesRep);
