Print a list according to the number of labels

Question

My C# Console Application has a list of 7 items in all, and you need to print these items on a label. By default each label fits 5 items. I’m not able to print the items according to the amount of labels.

So what I did (very simply) was:

int nrEtiquetas = Lista.Count / 5

for(int contador = 0; contador <= nrEtiquetas; contador ++)
{
  for(int i = 0; i <= 5; i++)
  {
    MessageBox.Show("Item: " i.ToString())
  }
}
EnviaParaImpressora();

Meanwhile the imprint is on loop and the two remaining items are not displayed.

As comments, start by correcting the division.

Using Math.Ceiling you can divide by rounding up:

int nrEtiquetas = (int)Math.Ceiling((double)Lista.Count / 5);

The code so far would look like this and doesn’t change much of yours, except for the fact that you should use the < and not the <=. In addition, I created a fictitious list of string as if it were your labels.

using System;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        List<string> Lista = new List<string>{
            "Etiqueta 1",
            "Etiqueta 2",
            "Etiqueta 3",
            "Etiqueta 4",
            "Etiqueta 5",
            "Etiqueta 6",
            "Etiqueta 7",
        };

        int nrEtiquetas = (int)Math.Ceiling((double)Lista.Count / 5);

        for(int quantidade = 0; quantidade < nrEtiquetas; quantidade ++)
        {

            //Aqui você precisa corrigir seu loop, a lógica dele está errada.

            EnviaParaImpressora();
        }
    }

    public static void EnviaParaImpressora()
    {
        Console.WriteLine("Enviado para impressora...");
        Console.WriteLine("");
    }
}
