使用分隔符从文本文件中读取字符串 [英] Reading a string from text file with delimiters

问题描述

大家好，我有这样的文字文件



第1行：{'DEPT-ELECTRICAL';'用户';

第2行：'这是DMM的第一次演出。'; TIME：12：00：00’ ; '版本：6.1.2

第3行：';'F01RY0DM08';'＃history';'UP8';



我需要用单引号作为单个字符串来考虑和读取内容。例如，输出应该是String1 = DEPT-ELECTRICAL，String2 = USER ...

半冒号是这里的分隔符。



我已经在网上提到了一些解决方案。我复制了一些代码用于启动，虽然它不是我需要的但是它给了我一个错误，因为foreach声明不能应用于Systems.Text.Regularexpr.match类型的变量。请帮助我



我尝试过：

  //  读取文件中的所有文字 
  string  sData = File.ReadAllText（ @  c：/file.txt）; 
 
  //  匹配字符串 
匹配匹配= Regex.Match（sData， < span class =code-string> \（\\w | \\d | \\\\ | \\\）* \  ，
 RegexOptions.IgnoreCase）; 
 
  //  读取结果并删除out of them  
  foreach （ var  sResult  in  match）
 {
 sResult = sResult.Remove（ 0 ， 1 ）。删除（sResult） .length  -   2 ， 1 ）; 
  //  使用sResult执行任何操作 
} 

解决方案

匹配只是一个结果。你正在寻找收集结果，匹配

 MatchCollection matches = Regex .Matches（... 
  foreach （匹配匹配在 matche中s）{
  string  sResult = match.Value 
 ... 

< blockquote>我担心你的RegEx与你想要的不匹配。

尝试类似：'（。+）';



以下是RegEx文档的链接：

hi all, i have text file like this

LINE 1: {'DEPT-ELECTRICAL';'USER';
LINE 2: 'This is the first performance for DMM.'; 'TIME:12:00:00'; 'VERSION:6.1.2
LINE 3: ';'F01RY0DM08';'#history';'UP8";

I need to consider and read the contents with in single quotes as a single string. For eg., the output should be String1 = DEPT-ELECTRICAL, String2 = USER...
Semi colon is the delimiter here.

I have referred some solutions online. I copied some code for a head start eventhough it's not exactly what i require but it's giving me an error as "foreach statement cannot be applied to variables of type Systems.Text.Regularexpr.match". please help me

What I have tried:

// Read all text from file
                string sData = File.ReadAllText(@"c:/file.txt");

                // Match strings between " "
                Match match = Regex.Match(sData, "\"(\\w|\\d|\\s|\\\")*\"",
                                          RegexOptions.IgnoreCase);

                // Read results and strip " out of them
                foreach (var sResult in match)
                {
                    sResult = sResult.Remove(0, 1).Remove(sResult.length - 2, 1);
                    // Do whatever with sResult
                }

解决方案

A match is only a single result. You are looking for the collection result, "Matches"

MatchCollection matches = Regex.Matches(...
foreach (Match match in matches) {
   string sResult = match.Value
   ...

I fear your RegEx do not match what you looking for.
Try something like: "'(.+)';"
