如何：初始化数组 (Visual C#)
更新：2007 年 11 月
本示例显示用三种不同方法初始化不同类型的数组：一维、多维和交错。
示例
// Single-dimensional array (numbers).
int[] n1 = new int[4] {2, 4, 6, 8};
int[] n2 = new int[] {2, 4, 6, 8};
int[] n3 = {2, 4, 6, 8};
// Single-dimensional array (strings).
string[] s1 = new string[3] {"John", "Paul", "Mary"};
string[] s2 = new string[] {"John", "Paul", "Mary"};
string[] s3 = {"John", "Paul", "Mary"};
// Multidimensional array.
int[,] n4 = new int[3, 2] { {1, 2}, {3, 4}, {5, 6} };
int[,] n5 = new int[,] { {1, 2}, {3, 4}, {5, 6} };
int[,] n6 = { {1, 2}, {3, 4}, {5, 6} };
// Jagged array.
int[][] n7 = new int[2][] { new int[] {2,4,6}, new int[] {1,3,5,7,9} };
int[][] n8 = new int[][] { new int[] {2,4,6}, new int[] {1,3,5,7,9} };
int[][] n9 = { new int[] {2,4,6}, new int[] {1,3,5,7,9} };
编译代码
复制该代码，并将其粘贴到控制台应用程序的 Main 方法中。
可靠编程
如果该数组并未在声明时初始化，数组成员将自动被初始化为该数组类型的默认初始值。如果数组声明是某类型的字段，则实例化该类型时，数组将被设置为默认值 null。
