How I call a variable declared in a method

Question

Hello, First I wanted to make it clear that I’m kind of new at programming okay?. Well my problem is that I need to do a method where I ask the user a name, then confirm the name, if the answer is yes, continue the program, but if not, it repeats the question. But the problem is in the variable name, how do I make this program work? Ps: I am doing this in method format because I will use it several times so so I imagine it will be easier in the future of the code. Ps: there is a commented part in the code so if I need to go back with it I don’t need to write it all over again.

I tried to put the variable name in Class Program, but I don’t even know if it works, I also tried to pass this variable by the parameters n=of the method, but it didn’t work, someone can help me?

using System;
using System.Threading;

class Program {
  public static void Main (string[] args) {
    string Nome = " ";
    int Segundos = 0;
    int Minutos = 0;
    int Horas = 0;
    /*bool Passa = false;
    string Confirma;*/
    Confirmação("Qual o nome do evento?",$"O nome do evento é: {Nome} correto?","Okay, então, ");
  }
  public static void Confirmação(string texto, string texto2, string texto3, string nome){
    bool Passa;
    string Confirm;
    string Nome;
    Passa = false;
    while (Passa == false){
      Console.WriteLine(texto);
      Confirm =  Console.ReadLine();
      Console.WriteLine(texto2);
      if (Confirm == "Sim"){
        
        Passa = true;
      }else{

        Console.Write(texto3);
      }
    }
  }
}
