问题描述

大家好

推荐答案

您可以逐行阅读文本文件(请参阅 [ String.Split [

You may read the text file line by line (see "Code: Reading a Text File One Line at a Time (Visual C#)"[^]) until you hit the needed one.
Then you may use the String.Split[^] method to get requested fields.

//将整个文本框数据复制到字符串中
字符串strTextBoxData = YourTextbox.text;

string [] strSplitResult = str.Split("，StringSplitOptions.RemoveEmptyEntries);//字符串数组现在将具有按索引索引的所有数据

//whole textbox data is copied to a string
string strTextBoxData = YourTextbox.text;

string[] strSplitResult = str.Split(" ", StringSplitOptions.RemoveEmptyEntries);//string array will now have all data index by index
