        {
            string[] x = { "SUV 4402577816 ABC 00:00:00 109.127.100.33", "SUV 6651215553 ABC 00:00:00 109.127.104.75", "SUV 6651231564 ABC 00:00:00 93.91.192.232" };
            for (int i = 0; i<x.Length; i++)
            {
                string[] d = x[i].Split(' ');

您需要阅读MSDN的几篇文章.您需要了解处理文件和字符串函数(例如split)的知识.

MSDN:有关读取文本文件的信息 [ ^ ]

MSDN:String.split方法示例 [

Hi,

You need to go though couple of articles of MSDN. You need knowledge of handling files and string functions like split.

MSDN: Information on Reading Text File[^]

MSDN : String.split method example[^]

Read all related links from MSDN and try something yourself. I know you can do this.

Best of luck
Thanks

它将出现一个字符串，您需要在environment.newline上拆分.然后，您可以使用每个字符串的substring方法对其进行修剪.然后，您可以清除该框并遍历字符串，将它们添加到框中，并在它们之间再次使用Environment.NewLine.

对于编程新手"来说，这太复杂了，您应该上课，学习更多基础知识.

It will come a string, you need to split on environment.newline. Then you can use the substring method of each string to trim it. And then you can clear the box and iterate over the strings, adding them to the box, with Environment.NewLine between them again.

This is too complex for someone who is ''new to programming'', you should be in class, learning more basic things.
