Extract characters from a string

Check this

string input = "VIN-AK-002";
string pattern = @"VIN-(\w+)-\d+";
Match match = Regex.Match(input, pattern);
if (match.Success)
{
    Console.WriteLine(match.Groups[1].Value);
}

To extract the substrings "RL" and "AK" from the given strings "VIN-RL-0001" and "VIN-AK-002," you can use regular expressions in JavaScript. Here's an example of how you can achieve this:

```javascript
const strings = ["VIN-RL-0001", "VIN-AK-002"];

const extractedStrings = strings.map((str) => {
  const match = str.match(/VIN-(\w+)-/);
  return match ? match[1] : null;
});

console.log(extractedStrings);
```

Output:
```
["RL", "AK"]
```

In the code above, we use the `match` method with a regular expression pattern `/VIN-(\w+)-/` to match the desired substring. The `(\w+)` part captures one or more word characters (letters, digits, or underscores) between "VIN-" and "-". The captured substring is then extracted using `match[1]`. The `map` function is used to apply this logic to each string in the `strings` array.

The resulting `extractedStrings` array will contain the extracted substrings "RL" and "AK" from the original strings.

Try below function:

static string ExtractValue(string input, string pattern)
    {
        Match match = Regex.Match(input, pattern);
        if (match.Success)
        {
            return match.Groups[1].Value;
        }
        return null; // or return an empty string, depending on your preference
    }

Use like below:

static void Main()
    {
        string[] strings = { "VIN-RL-0001", "VIN-AK-002" };
        string pattern = @"VIN-(\w{2})-\d+";

        foreach (string str in strings)
        {
            string extractedValue = ExtractValue(str, pattern);
            Console.WriteLine(extractedValue);
        }
    }

Thanks

Using regular expressions
 
 

var rl = Regex.Match("VIN-RL-0001", @"\bRL\b").Value;
var ak = Regex.Match("VIN-AK-002", @"\bAK\b").Value;

var rl = "VIN-RL-0001".Substring(0, 2);

var ak = "VIN-AK-002".Substring(0, 2);

Using LINQ

1. Using regular expressions

You can use regular expressions to extract the desired characters. The following regular expression will extract the two characters that come after the hyphen:

\w{2}

This regular expression will match any two consecutive word characters. In this case, the word characters are letters and numbers.

2. Using string slicing

You can also use string slicing to extract the desired characters. The following code will extract the two characters that come after the hyphen:

strings = ["VIN-RL-0001", "VIN-AK-002"]

for string in strings:
    extracted_characters = string[4:6]
    print(extracted_characters)

    
3. Using a for loopYou can also use a for loop to extract the desired characters. The following code will do this:    
    

strings = ["VIN-RL-0001", "VIN-AK-002"]

for i in range(len(strings)):
    extracted_characters = strings[i][4:6]
    print(extracted_characters)

Hello Ramco,

You can use split method and then you can skip first element.

string str = "VIN-AK-002";

var result = str.Split('-').Skip(1).FirstOrDefault();

out put : AK
