    private void btnGravarNovosValores_Click_1(object sender, EventArgs e)
    {
        string descricao;
        string textBoxX;

        int i = 0;
        foreach (Object texto in lstTabelaProdutosPreco.Items)
        {
            descricao = texto.ToString();
            i++;
            textBoxX = ("textBox" + i.ToString());

            //MessageBox.Show(descricao + " " + textBox);

            TabelaAlterarProdutosCalibresValores tabelaAlterarProdutosCalibresValores = new TabelaAlterarProdutosCalibresValores();
            tabelaAlterarProdutosCalibresValores.idTabelaPrecos = Convert.ToInt32(lstNome.SelectedValue.ToString().Substring(0, 3));
            tabelaAlterarProdutosCalibresValores.idProduto = Convert.ToInt32(descricao.ToString().Substring(0, 4));
            tabelaAlterarProdutosCalibresValores.idCalibre = descricao.ToString().Substring(8, 5);
            tabelaAlterarProdutosCalibresValores.precoVenda = double.Parse(textBoxX.ToString().Trim());
            if (tabelaAlterarProdutosCalibresValores.UpDateDefault())
            {
                MessageBox.Show(lstNome.SelectedValue.ToString().Substring(0, 3) + descricao.ToString().Substring(0, 4) + descricao.ToString().Substring(8, 5) + textBoxX);
            }
        }

    I didn’t understand. Could I talk a little more in the body of the question? Just the title and this code didn’t tell me much

  • I can build Textbox names through a textbox cycle +i = textbox1, but I can’t use it as the name of the textbox tableAlteRodusCalibresValue = double. Parse(textBoxX.Tostring(). Trim());

  • "build the names" of textbox ?!?! try to be clearer young

  • string Description; string textBoxX; int i = 0; foreach (Object text in lstTabelaProductsPreco.Items) { Description = text.Tostring(); i++; textBoxX = ("textbox" + i.Tostring()); }

  • You want to access a textbox that is in your form by entering its name in a string. This ?

  • Welcome to Stackoverflow, to start make a [tour] and then see [Ask] and [Answer]. Always inform a minimal, complete and verifiable example

  • through the foreach cycle with you each turn get a description and build a textbox name. when I will use the textbox name

  • you are only asking the wrong question young, What you want is to access the Textbox on your screen dynamically, inside the loop. Ie by the string "textBox"+i.ToString() Voce wants access to control: string texto = textBox1.Text;

  • if I try to use the name created daigual a textbox (textboxX) in a messagebox appears the correct name, if I try to use the same Textboxx to insert the contents of the textbox in a database, from the error "input string with incorrect format"

  • that’s it, how do I get the string recognized as a textbox

  • Sorry is the 1 time I am using this site and do not know how to ask the questions

  • no problems, see if my answer help and access the tour indicated by Everson

You want to access several TextBox that exist in your Form, dynamically, inside the loop.

For this you will use the Method Find:

https://msdn.microsoft.com/en-us/library/system.windows.forms.control.controlcollection.find(v=vs.110). aspx

Example:

for (int i =0; i< 10; i++)
{

        Control[] controls = this.Controls.Find("textBox" + i.ToString(), true);
        if (controls.Length > 0)
        {
            TextBox txtBox = controls[0] as TextBox;
            if (txtBox != null)
            {
                tabelaAlterarProdutosCalibresValores.precoVenda = txtBox.Text; 
            }
        }
        else
        {
          //não achou o textbox
        }

 }

  • It Worked Obligated
