推荐答案

您是说文件包含7行3个数字还是3行7个数字?
两种方法的原理都是相同的(我假设您的文件包含N行的3个数字，而您希望输出3行的N个数字).但是，由于这是作业的味道，我不会给您代码...
1)设置三个StringBuilder-每个输出一个，以及基于字符串的分隔符，最初是一个空字符串
2)从文件中读取一行
3)在空格字符上分割行(使用string.Split)
4)检查您是否完全由三个部分组成，如果没有报告错误，请停止.
5)使用AppendFormat("{0} {1}"，分隔符，splitpart)将每个部分添加到适当的stringbuilder中.
6)将分隔符设置为逗号
7)文件中仍然有行时，请从2开始重复.

Do you mean that your file contains 7 lines of 3 numbers, or three lines of seven numbers?
Either way the principle is the same (I will assume your file contains N lines of three numbers, and you want three lines of N numbers as output). But, as this smells of homework, I won''t give you code...
1) Set up three StringBuilders - one for each output, and string based separator, initially an empty string
2) Read a line from the file
3) Split the line (using string.Split) on the space character
4) Check you have exactly three parts, if not report an error and stop.
5) Add each part to the appropriate stringbuilder, using AppendFormat("{0}{1}", separator, splitpart)
6) Set the separator to a comma
7) While there are still lines in the file, repeat from 2.
