Instead of displaying text line by line display the whole text

Question

Instead of displaying text line by line display the entire text. Visual Studio Community 2017.

Stream entrada = File.Open(varexe + "\\Score.txt", FileMode.Open);
StreamReader leitor = new StreamReader(entrada);
string linha = leitor.ReadLine();
while (linha != null)
{
    MessageBox.Show(linha);
    linha = leitor.ReadLine();
}
leitor.Close();
entrada.Close();

Answer 1

Use the method ReadToEnd() and try to use using, when working with Stream and File, this will ensure the Dispose() of the object as soon as it is no longer allocated

string texto = string.Empty;

using (Stream entrada = File.Open(varexe + "\\Score.txt", FileMode.Open))
{
    StreamReader leitor = new StreamReader(entrada);
    texto = leitor.ReadToEnd();
}

MessageBox.Show(texto);
