将输入值保存在2dimention数组中

Question

如何在二维数组中保存用户在文本框中输入的数字？

例如：

我在文本框中有这个数字：45,78 现在我想像这样保存45,32：array [0,0] = 45和array [0,1] = 78

我该怎么办呢？非常感谢

编辑： 哦，当我在文本框中输入1,2,3,4,5,6,7,8,9并且需要[2,2] = 56

 private void button10_Click(object sender, EventArgs e)
    {
  int matrixDimention = 2;
        int[,] intValues = new int[matrixDimention + 1, matrixDimention + 1];
        string[] splitValues = textBox9.Text.Split(',');
        for (int i = 0; i < splitValues.Length; i++)
            intValues[i % (matrixDimention + 1), i % (matrixDimention + 1)] = Convert.ToInt32(splitValues[i]);
        string a=intValues[2,2].ToString();
        MessageBox.Show(a);

   }

当我采取：

string a=intValues[2,1].ToString();

Answer 1

请查看使用String.Split Method (Char[])和Convert.ToInt32 Method (String)

像

这样的东西

string textBox = "45,78";
int[,] values = new int[1,2];
string[] textBoxSplit = textBox.Split(',');
values[0, 0] = Convert.ToInt32(textBoxSplit[0]);
values[0, 1] = Convert.ToInt32(textBoxSplit[1]);

修改

使用List和Linq的示例

string textBox = "45,78,1,2,3,4,5,6,7,8,9,10,11,12";
List<int> list = new List<int>(textBox.Split(',').Select(x => Convert.ToInt32(x)));

使用List和foreach

的Longwinded示例

string textBox = "45,78,1,2,3,4,5,6,7,8,9,10,11,12";
List<int> list2 = new List<int>();
string[] splitVals = textBox.Split(',');
foreach (string splitVal in splitVals)
    list2.Add(Convert.ToInt32(splitVal));

修改

输入矩阵

string textBox = "1,2,3,4,5,6,7,8,9";
int matrixDimention = 2;
int[,] intValues = new int[matrixDimention + 1, matrixDimention + 1];
string[] splitValues = textBox.Split(',');
for (int i = 0; i < splitValues.Length; i++)
    intValues[i/(matrixDimention + 1), i%(matrixDimention + 1)] = Convert.ToInt32(splitValues[i]);

修改

跟随白兔

string textBox = "1,2,3,4,5,6,7,8,9";
int matrixDimention = 2;
int[,] intValues = new int[matrixDimention + 1, matrixDimention + 1];
string[] splitValues = textBox.Split(',');
for (int i = 0; i < splitValues.Length; i++)
    intValues[i/(matrixDimention + 1), i%(matrixDimention + 1)] = Convert.ToInt32(splitValues[i]);
string displayString = "";
for (int inner = 0; inner < intValues.GetLength(0); inner ++)
{
    for (int outer = 0; outer < intValues.GetLength(1); outer++)
        displayString += String.Format("{0}\t", intValues[inner, outer]);
    displayString += Environment.NewLine;
}
MessageBox.Show(displayString);

Answer 2

试试这个假设数组是一个字符串数组

str[] input = textBox.Text.Split(',');

 if(input.Length > 1)
  {
     arr[0,0] = input[0];

     arr[0,1]= input[1];

   }
