c＃按钮点击事件。(c# button click event. Extracting the coordinates from a two dimensional array)

 我在c＃上制作游戏扫雷，我的代码的这部分是检查用户是否按下网格上的某个按钮。 然而，这样做的方式我相信它分割了他按下的按钮的xy坐标。 
 
 这意味着代码的工作方式是这里有两个二维数组。 有100个按钮按钮[10,10]。 后面是一个叫做网格的网格[10,10]，在网格上我说-1是炸弹，1是空的空间。 我试图从按钮中提取他按下的xy坐标并用它检查网格。 这是下面的代码： 
 
 但是，当我按下一个按钮 - 代码int x = System.Convert.ToInt32（split [0]）; 我得到'System.FormatException'。 
 
 我究竟做错了什么？ 
 
void bttnOnclick(object sender, System.EventArgs e)
    {

        Button bttnClick = sender as Button;

        string[] split = bttnClick.Name.Split(new Char[] { ' ' });

        int x = System.Convert.ToInt32(split[0]);
        int y = System.Convert.ToInt32(split[1]);


        if (grid[x, y] == -1)
        {
            //Game Over!
            for (int xx = 0; xx < SizeX; xx++)
            {
                for (int yy = 0; yy < SizeY; yy++)
                {
                    if (grid[xx, yy] == -1)
                    {
                        buttons[xx, yy].Visible = false;
                    }

                }
            }
        }
    }

I am making the game minesweeper on c# and this part of my code is checking to see if the user pressed a certain button on the grid. However, the way to do that I believe it split the x y coordinates of the button he pressed.
 
Meaning the way the code works is that there are two 2-dimensional array going on here. There are 100 buttons button[10,10]. and behind that is a grid called grid[10,10] and on the grid I said -1 is a bomb and 1 is an empty space. I am trying to extract the x-y coordinate that he presses from the button and check the grid with it. And this is the code below:
 
However,when I press a button - at code int x = System.Convert.ToInt32(split[0]); I get a 'System.FormatException'.
 
What am I doing wrong?
 
void bttnOnclick(object sender, System.EventArgs e)
    {

        Button bttnClick = sender as Button;

        string[] split = bttnClick.Name.Split(new Char[] { ' ' });

        int x = System.Convert.ToInt32(split[0]);
        int y = System.Convert.ToInt32(split[1]);


        if (grid[x, y] == -1)
        {
            //Game Over!
            for (int xx = 0; xx < SizeX; xx++)
            {
                for (int yy = 0; yy < SizeY; yy++)
                {
                    if (grid[xx, yy] == -1)
                    {
                        buttons[xx, yy].Visible = false;
                    }

                }
            }
        }
    }
