Analog of php function strtr in .Net

Question

.NET

Can you please tell me how to perform such a function in .Net?

For example

$a=array("o" => "l", "l" => "o");
$b=strtr("ololo",$a);

As I understand it, a simple pass through the array will not work, because otherwise it turns out
1) lllll
2) ooooo
And it should turn out lolol

using System.Text;
using System.Collections.Generic;

class Program
{
  public static void Main(string[] args)
  {
    var repl = new Dictionary<char, char> { {'o', 'l'}, {'l','o'} };
    var src = "ololo";
    Console.WriteLine("Source string: " + src + "; changed string: " + src.Strtr(repl));
    Console.ReadKey();
  }
}

public static class StringExt
{
  public static string Strtr(this string src, Dictionary<char, char> replacePairs) {
    var sb = new StringBuilder();
    foreach (char c in src) {
      if(replacePairs.ContainsKey(c)) {
        sb.Append(replacePairs[c]);
      } else {
        sb.Append(c);
      }
    }
    
    return sb.ToString();
  }
}
