How to change Java’s final property to C#?

Question

Which property in C# corresponds to final Java, I need to change my variables final String mensagem = "Tokio Marine Seguradora S.A."; to something corresponding in C#.

using System;

namespace ConsoleApplication
{
    public sealed class Criptografia
    {
        private static readonly String ALGORITMO = "AES";

        public static String descriptografar(String mensagem, String chave) 
        {

          //  final Cipher cipher = getCipher(Cipher.DECRYPT_MODE, chave);

          //  final byte[]
          //  descriptografado = cipher.doFinal(Base64.decodeBase64(mensagem));

                //return new String(descriptografado, "UTF-8");

            return "";
        }

        public static void Main(string[] args)
        {
            // Mensagem que sera criptografada.
            final String mensagem = "Tokio Marine Seguradora S.A.";

            // Senha definida da operadora.
            final String chave = "JessicaBiel";

            //// Valor criptografado.
            //String criptografado = Criptografia.criptografar(mensagem, chave);
            //Console.Write("Valor criptografado: '%s' %n", criptografado);

            //// Valor original.
            //String descriptografado = Criptografia.descriptografar(criptografado, chave);
            //Console.Write("Valor descriptografado: '%s'", descriptografado);

            Console.ReadKey();
        }
    }
}

Answer 1

In the context of the question is const, but in fact it is not usually useful and practically never seen being used. " Constants" within a local scope help very little (slightly helps in performance).

Other contexts

In class or instance variables is the readonly which equals to final java.

If it were in a class, the equivalent would be sealed.

In methods the default C# method is not virtual, so you don’t need it. Unless you want to prevent virtuality in a tree where the method was already virtual, then the use should be sealed also, next to the override.

Extra

Ideally it would be good to convert idiomatically. It gets weird to have a Java style in C#code. And it is easy to end up making some mistake so.
