尝试使用C#将int []转换为int [,]

int[] sourceArray = { 1, 2, 3, 4, 5, 6 };
int rows = 2;
int columns = 3;

int[,] targetArray = new int[rows, columns];

for (int i = 0; i< rows; i++)
{
    for (int j = 0; j< columns; j++)
    {
        int index = i * columns + j;
        if (index< sourceArray.Length)
        {
            targetArray[i, j] = sourceArray[index];
        }
        else
        {
            break;
        }
    }
}
