删除方法不删除 [英] delete method not deleting

问题描述

我制作了一个包含三个阵列的程序：一个用于姓氏，一个用于得分，一个用于玩家号码。现在，我得到了所有的数组和一切，但由于某种原因我的ProcessDelete方法没有删除数据



任何帮助将不胜感激

Hi, I made a program that holds three arrays: one for the persons last name, one for the points scored and one for the player number. Now, I got all the arrays and everything done but for some reason my ProcessDelete method Isn't deleting the data

Any help would be appreciated

static  Int32[] ProcessDelete(Int32[] playerNumbers, ref Int32 playerCount, String[] playerLastName, Int32[] playerPoints )
        {
            Int32[] newArray = new Int32[playerNumbers.Length - 1]; String[] newArray2 = new String[playerLastName.Length - 1]; Int32[] newArray3 = new Int32[playerPoints.Length - 1];

            int index = 0;
            int index2 = 0;
            int index3 = 0;
            int j = 0;
            int k = 0;
            int t = 0;
            while (index < playerNumbers.Length)
            {
                if (index != playerCount)
                {
                    newArray[j] = playerNumbers[index];
                    j++;
                }

                index++;
            }

            while (index2 < playerLastName.Length)
            {
                if (index2 != playerCount)
                {
                    newArray2[k] = playerLastName[index2];
                    k++;
                }

                index2++;
            }
              while (index3 < playerLastName.Length)
            {
                if (index3 != playerCount)
                {
                    newArray3[t] = playerPoints[index3];
                    t++;
                }

                index3++;
            }
            return newArray;
        }

        static void DeletePlayer(Int32[] playerNumbers, String[] playerLastName, Int32[] playerPoints, ref Int32 playerCount, Int32 MAXPLAYERS)
        {
            int player;// Player number to delete
            int playerindex;//index of the player number in Array
            if (playerCount < MAXPLAYERS)
            {

                player = GetPositiveInteger("\nDelete Player: please enter the player's number");
                playerindex = GetPlayerIndex(player, playerNumbers, playerCount);


               if (playerindex != -1)
                {

                    {

                        Console.WriteLine("\nDelete Player: Number - {0}, Name - {1}, Points - {2}", playerNumbers[playerindex], playerLastName[playerindex], playerPoints[playerindex]);
                        Console.WriteLine("Succesfully Deleted");
                        Console.WriteLine();
                        ProcessDelete(playerNumbers, ref playerCount, playerLastName, playerPoints);
                    }
                }
                else
                    Console.WriteLine("\nDelete Player: player not found");
            }
            else
                Console.WriteLine("\nDelete Player: the roster is empty");
        }

    }
}

推荐答案

我会这样做，找到索引并使用数组发送并删除它。

I would do as below, find the index and send with array and delete it.

void Main()
{
    int[] test = ProcessDelete(new int[]{ 1, 3, 4, 9, 2 }, 3);
    //test: 1,3,4,2

}

int[] ProcessDelete(int[] playerNumbers, int index)
{
  if(playerNumbers!=null && playerNumbers.Length>0 && index>-1)
     playerNumbers = playerNumbers.Where((val, idx) => idx != index).ToArray();
    return playerNumbers;
}

你最好使用List而不是数组，然后你可以简单地调用删除 [ ^ ]按索引删除项目的方法。

You better use List instead of array, then you can simply call RemoveAt[^] method to remove item by index.
