C# 对象的多维数组

C#中的多维数组：解析与应用

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

csharp
int element = twoDArray[1, 2];

csharp
int[,] matrix = {
    {1, 2, 3},
    {4, 5, 6},
    {7, 8, 9}
};
// 计算每行的总和
for (int i = 0; i < 3; i++)
{
    int rowSum = 0;
    for (int j = 0; j < 3; j++)
    {
        rowSum += matrix[i, j];
    }
    Console.WriteLine($"第{i + 1}行的总和为：{rowSum}");
}
// 计算每列的总和
for (int j = 0; j < 3; j++)
{
    int colSum = 0;
    for (int i = 0; i < 3; i++)
    {
        colSum += matrix[i, j];
    }
    Console.WriteLine($"第{j + 1}列的总和为：{colSum}");
