C#一个数组元素按照另一个数组个数和元素进行分割

Question

下面有三个数组count，nums，dataX：

    int[] count = { 7, 7, 8, 7, 8 };
    int[] nums = { 1, 2, 3, 4, 5, 6, 7,
                           8, 9, 10, 11, 12, 13, 14,
                           15, 16, 17, 18, 19, 20, 21, 22,
                           23, 24, 25, 26, 27, 28, 29,
                           30, 31, 32, 33, 34, 35, 36, 37 };
 double[] dataX = { 177.913, 255.971, 333.692, 411.355, 489.050, 644.143, 721.401,
                               178.549, 334.009, 411.455, 489.294, 566.739, 644.123, 721.374,
                               179.099, 256.591, 334.402, 411.610, 489.459, 566.774, 644.050, 721.051,
                               179.629, 257.088, 334.524, 412.156, 566.736, 643.818, 720.929,
                               180.370, 257.899, 335.304, 412.456, 489.839, 566.349, 643.582, 720.607 };            

如何将dataX和nums中的元素根据按照count中的元素进行分割，分别分割成5个（即count的长度）子数组，每个子数组中的元素个数和对应count中的元素值相同？如下图所示：

            int[] nums1 = { 1, 2, 3, 4, 5, 6, 7 };
            int[] nums2 = { 8, 9, 10, 11, 12, 13, 14 };
            int[] nums3 = { 15, 16, 17, 18, 19, 20, 21, 22 };
            int[] nums4 = { 23, 24, 25, 26, 27, 28, 29 };
            int[] nums5 = { 30, 31, 32, 33, 34, 35, 36, 37 };
            double[] X1 = { 177.913, 255.971, 333.692, 411.355, 489.050, 644.143, 721.401 };
            double[] X2 = { 178.549, 334.009, 411.455, 489.294, 566.739, 644.123, 721.374 };
            double[] X3 = { 179.099, 256.591, 334.402, 411.610, 489.459, 566.774, 644.050, 721.051 };
            double[] X4 = { 179.629, 257.088, 334.524, 412.156, 566.736, 643.818, 720.929 };
            double[] X5 = { 180.370, 257.899, 335.304, 412.456, 489.839, 566.349, 643.582, 720.607 };

思路：

1. 首先将count中的元素进行累加得到总数total。
2. 然后根据得到的total将nums和dataX中的元素分割成total个数的一维数组。
3. 最后将一维数组中的元素按照count中的值进行分割，得到所需的五个子数组。 代码实现：

int[] count = {7, 7, 8, 7, 8};
int[] nums = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37};
double[] dataX = {177.913, 255.971, 333.692, 411.355, 489.050, 644.143, 721.401, 178.549, 334.009, 411.455, 489.294, 566.739, 644.123, 721.374, 179.099, 256.591, 334.402, 411.610, 489.459, 566.774, 644.050, 721.051, 179.629, 257.088, 334.524, 412.156, 566.736, 643.818, 720.929, 180.370, 257.899, 335.304, 412.456, 489.839, 566.349, 643.582, 720.607};
int total = 0;
for (int i = 0; i < count.length; i++) {
    total += count[i];
}
int[] nums1 = new int[count[0]];
int[] nums2 = new int[count[1]];
int[] nums3 = new int[count[2]];
int[] nums4 = new int[count[3]];
int[] nums5 = new int[count[4]];
double[] X1 = new double[count[0]];
double[] X2 = new double[count[1]];
double[] X3 = new double[count[2]];
double[] X4 = new double[count[3]];
double[] X5 = new double[count[4]];
int index1 = 0;
int index2 = 0;
int index3 = 0;
int index4 = 0;
int index5 = 0;
for (int i = 0; i < total; i++) {
    if (i < count[0]) {
        nums1[i] = nums[i];
        X1[i] = dataX[i];
    } else if (i < count[0] + count[1]) {
        nums2[index1] = nums[i];
        X2[index1] = dataX[i];
        index1++;
    } else if (i < count[0] + count[1] + count[2]) {
        nums3[index2] = nums[i];
        X3[index2] = dataX[i];
        index2++;
    } else if (i < count[0] + count[1] + count[2] + count[3]) {
        nums4[index3] = nums[i];
        X4[index3] = dataX[i];
        index3++;
    } else {
        nums5[index4] = nums[i];
        X5[index4] = dataX[i];
        index4++;
    }
}
System.out.println(Arrays.toString(nums1));
System.out.println(Arrays.toString(nums2));
System.out.println(Arrays.toString(nums3));
System.out.println(Arrays.toString(nums4));
System.out.println(Arrays.toString(nums5));
System.out.println(Arrays.toString(X1));
System.out.println(Arrays.toString(X2));
System.out.println(Arrays.toString(X3));
System.out.println(Arrays.toString(X4));
System.out.println(Arrays.toString(X5));

输出结果：

[1, 2, 3, 4, 5, 6, 7]
[8, 9, 10, 11, 12, 13, 14]
[15, 16, 17, 18, 19, 20, 21, 22]
