How to generate an automatic sequential number in C#

Question

Good afternoon..

I have a txtbox1.Tex in my form, and I need to generate a 2-digit sequential number automatically. EX 01, 02, 03 and so on, and shows in txtbox.

Could someone help me.

Thank you.

Answer 1

On the form:

private int _contador = 0;

In the method in which you will change the text:

this._contador++;
this.txtBox1.Text = this._contador.ToString().PadLeft(2, '0');

The method PadLeft class String receives two parameters. The first tells you the minimum length you wish to have, and the second tells you which character you will fill out on the left.

Answer 2

Create a Genero method

private void Gerar()
{
  // Gerando Código Incremento
   this._contador++;
   this.Codigo.Text = this._contador.ToString().PadLeft(2, '0');
 }

in Lod

 private void Cliente_Load(object sender, EventArgs e)
  {

            Gerar();

  }
