C# 手动填充 double[][]

手动填充 C# 中的 double[][] 数组

csharp
double[][] myArray = new double[3][];
myArray[0] = new double[] { 1.0, 2.0, 3.0, 4.0 };
myArray[1] = new double[] { 5.0, 6.0, 7.0, 8.0 };
myArray[2] = new double[] { 9.0, 10.0, 11.0, 12.0 };

csharp
using System;
class Program
{
    static void Main()
    {
        // 声明并初始化 double[][] 数组
        double[][] myArray = new double[3][];
        // 手动填充数组
        FillArrayManually(myArray);
        // 打印数组内容
        PrintArray(myArray);
    }
    static void FillArrayManually(double[][] array)
    {
        // 循环填充数组
        for (int i = 0; i < array.Length; i++)
        {
