How do I Split the string into two separate variables in C#

I have a string that I want to store in two different varaibles in C#.

s= "Name=team1; ObjectGUID=d8fd5125-b065-48cb-b5f3-c20f509b7476"

I want Var1 = team1 & Var2 = d8fd5125-b065-48cb-b5f3-c20f509b7476

Here's what I am trying to do:

var1 = s.Replace("Name=","").Replace("; ObjectGUID=", "");

But I am not able to figure out how to bifurcate the Name value to var1 and eliminate the rest. And it is possible that the value of 'Name' could vary so I can't fix the length to chop off.

You could use a regex where the value of Name could be captured in group 1 matching not a ; using a negated character class.

The value of ObjectGUID could be captured in group 2 using a repeated pattern matching 1+ times a digit 0-9 or characters a-f. Then repeat that pattern 1+ times preceded with a -

Name=([^;]+); ObjectGUID=([a-f0-9]+(?:-[a-f0-9]+)+)

.NET regex demo | C# demo

For example:

string pattern = @"Name=([^;]+); ObjectGUID=([a-f0-9]+(?:-[a-f0-9]+)+)";
string s= "Name=team1; ObjectGUID=d8fd5125-b065-48cb-b5f3-c20f509b7476";

Match m = Regex.Match(s, pattern);
string var1 = m.Groups[1].Value;
string var2 = m.Groups[2].Value;

Console.WriteLine(var1);
Console.WriteLine(var2);

Result

team1
d8fd5125-b065-48cb-b5f3-c20f509b7476

You can use IndexOf to take point at "=" and Substring to take the next value. using System;

       public class SubStringTest {
          public static void Main() {
            string [] info = { "Name: Felica Walker", "Title: Mz.", 
                               "Age: 47", "Location: Paris", "Gender: F"};
            int found = 0;

            Console.WriteLine("The initial values in the array are:");
            foreach (string s in info)
                Console.WriteLine(s);

            Console.WriteLine("\nWe want to retrieve only the key information. That 
             is:");        
            foreach (string s in info) {
                found = s.IndexOf(": ");
                Console.WriteLine("   {0}", s.Substring(found + 2));
            }
        }
      }

The example displays the following output: The initial values in the array are: Name: Felica Walker Title: Mz. Age: 47 Location: Paris Gender: F
We want to retrieve only the key information. That is: Felica Walker Mz. 47 Paris F

Split by ';' then split by '='. Also works for any key/value pairs such as the ones in connection strings.

var values = s.Split(';').Select(kv => kv.Split('=')[1]).ToArray();
var var1 = values[0];
var val2 = values[1];
