String [] []在C#中的含义是什么？

Question

例如.

String [ ][ ] LinesSplitByComma1 =
    File.ReadAllLines("Filepath").Select(s => s.Split(',')).ToArray();

Answer 1

一组字符串数组.

它正在读取文件并创建一个数组,其中每个元素都是文件中的一行,由用逗号分隔该行创建的字符串数组表示.

所以像文件一样

a,b,c
1,2,3
asdas,ertert,xcvxcvx

将表示为

LinesSplitByComma1[0][0] = "a"
LinesSplitByComma1[0][1] = "b"
LinesSplitByComma1[0][2] = "c"
LinesSplitByComma1[1][0] = "1"
LinesSplitByComma1[1][1] = "2"
LinesSplitByComma1[1][2] = "3"
LinesSplitByComma1[2][0] = "asdas"
LinesSplitByComma1[2][1] = "ertert"
LinesSplitByComma1[2][2] = "xcvxcvx"
