c#中的數組

1. 數組聲明

2. 數組初始化

3. 數組取值

 

1. 數組聲明

int[] table; // not int table[];  

int[] numbers; // declare numbers as an int array of any size  

numbers = new int[10]; // numbers is a 10-element array

numbers = new int[20]; // now it's a 20-element array

string[,] names = new string[5,4]; 

2. 數組初始化

int[] numbers = new int[5] {1, 2, 3, 4, 5};  

string[] names = new string[3] {"Matt", "Joanne", "Robert"};

int[,] numbers = new int[3, 2] { {1, 2}, {3, 4}, {5, 6} };  

string[,] siblings = new string[2, 2] { {"Mike","Amy"}, {"Mary","Albert"} };

3. 數組取值

int[] numbers = {10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0};  

numbers[4] = 5;

int[,] numbers = { {1, 2}, {3, 4}, {5, 6}, {7, 8}, {9, 10} }; 

numbers[1, 1] = 5;
