Question

这是我的变量

string[,] table = new string[104, 6];
int moveRow = 1;
int moveCol = 1;
int sum1 = 0;
int sum2 = 0;
int rowIndex1 = 1;
int rowIndex2 = 0;
int firstTableRow = 1;
int firstTableCol = 1;
int secondTableRow = 1;
int secondTableCol = 0;
int thirdTableRow = 0;
int thirdTableCol = 1;
int fourthTableRow = 0;
int fourthTableCol = 0;
int counterNextRow = 0;

现在它给了我（仅为我）一个奇怪的Array index is out of range这里

if (moveRow > 1)
{

   firstTableCol += 1;
   secondTableCol += 1;
   thirdTableCol += 1;
   fourthTableCol += 1;
   //r1 = table[2,1] r2 = table[2,0] r3 = table[1,1] r4 = table[1,0]
   string d1 = table[firstTableRow, firstTableCol]; //<------- HERE ITS GIVING ME THE ERROR
   string d2 = table[secondTableRow, secondTableCol];
   string d3 = table[thirdTableRow, thirdTableCol];
   string d4 = table[fourthTableRow, fourthTableCol];

   moveRow += 1;
}

这是我的整个代码

for(int col = 0; col < table.GetLength(0); col++){
     for (int row = 0; row < table.GetLength(1); row++)
     {               
            //if not equal length BLUE[0] else RED[1]
            //moverow = 1, movecol = 1 default
            if (table[moveCol, moveRow] == null)
            //1,1
            {
                //must be on table[2,0]
                //scan 
                //3,2
                string col1 = table[rowIndex1, row];
                string col0 = table[rowIndex2, row];

                if (col1 != null)
                {
                    sum1++;
                }
                if (col0 != null)
                {
                    sum2++;
                }
                counterNextRow += 1;
            }
            else
            {
                //if not null and on the first process
                if (counterNextRow == 0)
                {
                    //r1 = table[1,1] r2 = table[1,0] r3 = table[0,1] r4 = table[0,0]
                    string d1 = table[firstTableRow, firstTableCol];
                    string d2 = table[secondTableRow, secondTableCol];
                    string d3 = table[thirdTableRow, thirdTableCol];
                    string d4 = table[fourthTableRow, fourthTableCol];


                    if (d1 != null && d2 != null && d3 != null && d4 != null)

                        p.SetActive(true);
                    }

        rowIndex2++;
        moveCol++;
        moveRow = 1;
   }
 }

由于这个错误，我一直被困在这里，我不知道为什么它会给我Array index is out of range错误。我没有任何负数，所以据说我不会有那种错误。有人能指出我吗？

Answer 1

数组索引范围必须为0到103而不是1到104.它可能会解决您的问题。

int moveRow = 0;
int moveCol = 0;

Answer 2

您的moveRow和moveCol从1开始，您的for循环从0开始。因此，您的moveCol比您的for循环索引器高一个。

Answer 3

您的表格定义为char(0)但您似乎正在编入索引[columns, rows]

Answer 4

嗯，我忘了检查变量的长度到我正在使用的尺寸。所以通过这样做我的变量rowIndex1，我需要像这样检查它

if(rowIndex1 + 1 < table.GetLength(0)){
    rowIndex++;
}

当时感谢你们。

无法弄清楚这个“数组索引是否超出范围”错误
