Compare and replace text in large volumes of data

Question

I have a data dictionary with some abbreviations and I need to go through a list containing dozens and even hundreds of paragraphs in order to compare words and replace words with those abbreviations.

What is the Alternative (or Best Way) to Compare Large Data Strings Without Using Replace ?

I’ve never done anything like this, but from what I understand of your doubt, I’d start with a code like this:

class Program
    {
        static void Main(string[] args)
        {
            List<Dicionario> dicionario = new List<Dicionario>();
            //Carrega o dicionário

            string texto = @"texto gigante aqui
era uma vez, blabla bla";
            string novoTexto = "";
            string[] linhas = texto.Split('\r');

            for (int l = 0; l < linhas.Length;l++)
            {
                string[] palavras = linhas[l].Split(' ');
                for (int p = 0; p < palavras.Length; p++)
                {
                    Dicionario d = dicionario.Find(x => x.Palavra.ToUpper() == palavras[p].ToUpper());
                    if (d != null)
                        palavras[p] = d.Abreviacao;

                    novoTexto += palavras[p] + " ";
                }

                novoTexto += "\r";
            }

            //Seu novo texto
            Console.Write(novoTexto);

        }

        class Dicionario
        {
            public string Palavra { get; set; }
            public string Abreviacao { get; set; }
        }
    }

then I would do performance tests to try to improve something and see if this is really what you need.

hope I’ve helped
