将两个1D阵列（A []​​和B []）连接成一个2D数组（C [，]）

Question

我有两个1D阵列：

double A = new double[7] {4, 2, 54, 16, 9, 55, 27} 

和

double B = new double[7] {8, 88, 21, 12, 8, 30, 11}

我如何加入那些数组成为一个2D数组C [2,6]，它包含上面的1D数组？

可能是这样的：

double C = new double[2,7] {{4, 2, 54, 16, 9, 55, 27} , {8, 88, 21, 12, 8, 30, 11}};

我尝试了这段代码，但只打印了阵列A.

public static double[,] _matrix_byRow(double[] Mat1, double[] Mat2)
    {
        int i, j, y;
        double[,] newMat = new double[2, 7];

        for (i = 0; i < 2; i++)
        {
            for (j = 0; j < 7; j++)
            {
                newMat[i, j] = Mat1[j];
            }
        }
        for (i = 0; i < 2; i++)
        {
            for (y = 0; y < 7; y++)
            {
                newMat[i, y] = Mat2[y];
            }
        }
        return newMat;
    }

Answer 1

请改为尝试：

public static double[,] _matrix_byRow(double[] Mat1, double[] Mat2)
{
    double[,] newMat = new double[2, 7];

    for (var j = 0; j < 7; j++)
    {
        newMat[0, j] = Mat1[j];
        newMat[1, j] = Mat2[j];
    }

    return newMat;
}
