C# 创建数组的数组

## 创建C#数组的数组：灵活管理数据集合

csharp
int[,] multiDimensionalArray = new int[3, 4];

csharp
int[][] jaggedArray = new int[3][];
jaggedArray[0] = new int[4];
jaggedArray[1] = new int[2];
jaggedArray[2] = new int[5];

csharp
class Program
{
    static void Main()
    {
        // 创建包含学生成绩的数组的数组
        double[][] studentGrades = new double[3][];
        
        // 初始化每个学生的成绩
        studentGrades[0] = new double[] { 85.5, 90.0, 78.5 };
        studentGrades[1] = new double[] { 92.0, 88.5, 95.5, 89.0 };
        studentGrades[2] = new double[] { 78.0, 80.5 };
        // 输出学生成绩
        for (int i = 0; i < studentGrades.Length; i++)
        {
            Console.WriteLine($"Student {i + 1} Grades: {string.Join(", ", studentGrades[i])}");
        }
    }
}
