hello
i am elaborating a program that will read a file, modify it and sort its contents(if the contents are integers sort them into a listbox)
char letra = ' ';
string cad;
char[] numbers = { '1', '2', '3', '4', '5', '6', '7', '8', '9', '0', ' ' };
private void button2_Click(object sender, EventArgs e)
{
StreamReader sr = new StreamReader(textBox1.Text);
richTextBox1.Text = sr.ReadToEnd();
sr.Close();
for (int i = 0; i < richTextBox1.Text.Length; i++)
{
letra = richTextBox1.Text[i];
if (Array.IndexOf(letra, numbers) != -1)
{
cad = cad + letra;
listBox1.Items.Add(cad);
}
}
}
i think i have my condition all mixed up....can someone help me out with this?

Hi Cesarg! Glad to see you made it out of the blogs section. :)

You have a few problems with your code. This seems to be working.

char letra = ' ';
        string cad;
        char[] numbers = { '1', '2', '3', '4', '5', '6', '7', '8', '9', '0', ' ' };

        private void button1_Click(object sender, EventArgs e)
        {
              [COLOR=#006400]//StreamReader sr = new StreamReader(textBox1.Text);  Why are you using a stream reader to place the textBox.Text into the richTextBox?
              //sr.ReadToEnd(textBox1.Text);
              //richTextBox1.Text = sr.ReadToEnd();
              //sr.Close();[/COLOR]
              richTextBox1.Text = textBox1.Text()
              for (int i = 0; i < richtextBox1.Text.Length; i++)
              {
                letra = richtextBox1.Text[i];
                 if (numbers.Contains(Convert.ToChar(letra)))[COLOR=#006400]//Convert letra to char then see if it matches a value.[/COLOR]
                 {                    
                   cad += letra;[COLOR=#006400]// cad = cad call should be avoided.[/COLOR]
                   listBox1.Items.Add(cad);
                 }
              }
         }

Good luck ~ Committed.
