{


string strnumber = "";


TextBox2.Text = "";


foreach (char cha in TextBox1.Text) {


if (char.IsNumber(cha)) {


strnumber = strnumber + cha;


}


}


int intnumber = strnumber;


TextBox2.Text = intnumber;


}








You could just add each character to the textbox, so instead of:


strnumber = strnumber + cha;


you could do


textbox2.text = textbox2.text + cha;





but you said you wanted to store the number as an variable.


I think thats what you wanted, else, ask again and ill try to help.





So like... da21s3as12asasdas would become 21312
