Answer 1

遍历行，然后拷贝至一维数组中，性能稍微好点
[code="java"]
private static int[] unitTwoDimArray(int[][] src)
{
int row = src.length;
int col = src[0].length;

    int[] dst = new int[row * col];

    for (int i = 0; i < row; i++)
    {
        System.arraycopy(src[i], 0, dst, i * col, col);
    }

    return dst;
}

[/code]
