Hello, how can I split these strings as easily as possible:
var AL016 = "MS_FT_AL016_T";
var NF103 = "MS_FT_NF103_T";
var NF109 = "MS_FT_NF109_T";
var NF121 = "MS_FT_NF121_T";
var NF127 = "MS_FT_NF127_T";
var NF128 = "MS_FT_NF128_T";
var FTJmeno = "MS_FT_JMENO_P_T";
To make them look like this:
"AL016";
"NF103";
"NF109";
"NF121";
"NF127";
"NF128";
"JMENO_P";

Thank you so much

What I have tried:

I don't even know any function I could do.

Solution 1

Use either the .NET Regular Expressions | Microsoft Docs[^] or the String.Split Method (System) | Microsoft Docs[^].

In future it would help if you explained exactly how you want to split them.

Solution 2

It really depends on how reliable that data is: if t6he prefix you want to ignore is always 6 characters, and the suffix is 2 then the simplest solution is just to use teh string.Substring function:

string inp = "MS_FT_AL016_T";
string outp = inp.Substring(6, inp.Length - (6 + 2));

Although (MS_FT_)([A-Z]+[0-9]*(_[A-Z])*)(_T) regex seems not very promising but it can give you a good start.

Try this

C#

public class Example
{
   using System;
   using System.Text.RegularExpressions;

   public static void Main()
   {

      string[] dataList = {"MS_FT_AL016_T", "MS_FT_NF103_T", "MS_FT_NF109_T", "MS_FT_NF121_T", "MS_FT_NF127_T", "MS_FT_NF128_T", "MS_FT_JMENO_P_T"};

      foreach (string data in dataList)
      {
         Console.WriteLine("Input string: " + data);
         try {
             string pattern = @"(MS_FT_)([A-Z]+[0-9]*(_[A-Z])*)(_T)";  
            Regex rg = new Regex(pattern);  
 
            Match m = rg.Match(data);
            Console.WriteLine("Captured string: " + m.Groups[2].Value);

         }
         catch (Exception) {
            Console.WriteLine("Not matched");
         }
         Console.WriteLine();
      }
   }
}

Solution 4

Try this:

C#

string[] lines   = {"MS_FT_AL016_T", "MS_FT_NF103_T", "MS_FT_NF109_T", "MS_FT_NF121_T",
        "MS_FT_NF127_T", "MS_FT_NF128_T", "MS_FT_JMENO_P_T"};

string pattern = @"^(?>\w{2}_){2}(.*?)_";
Regex r = new Regex(pattern);
List<string> result = lines
    .Select(line => r.Matches(line)[0].Groups[1].Value)
    .ToList();
foreach(string s in result)
    Console.WriteLine(s);

It looks like you're always getting rid of the text "MS_FT_" and "_T". If that's true, I'd keep it simple and use the Replace function. Here's how it works.

myString.Replace([Text/variable I'm looking for], [Text/variable to replace it with]);

So you could do something like this...

string[] stringList = { "MS_FT_AL016_T", "MS_FT_NF103_T", "MS_FT_NF109_T", "MS_FT_NF121_T", "MS_FT_NF127_T", "MS_FT_NF128_T", "MS_FT_JMENO_P_T" };

for (int i = 0; i < stringList.Length; i++)
{
    stringList[i] = stringList[i].Replace("MS_FT_", "").Replace("_T", "");
    Console.WriteLine(stringList[i]);
}

If you're comfortable with Regex, then go ahead with one of the solutions above, but it sounds like you're kinda new to this, so I recommend knowing how it works in order to maintain it. The replace function is about as simple as it gets.
