Try the following: int sum = 0; int number; foreach (string line in textBox1.Lines) { int.TryParse(line out number); sum += number; } MessageBox.Show(sum is  + sum);

Krishna Garad · Answer

you can try this also List lst = new List (); string _no = txtno.Text; int _sum=0; for (int i = 0; i { if (_no[i]>=49&&_no[i] { lst.Add(int.Parse(_no[i].ToString())); } } foreach (int item in lst) { _sum += item; } txtsum.Text = _sum.ToString();

If your textbox contain values like 4 5 6 8 or 4 5 6 8 means new line or space is coming in no.Then try this List lst = new List (); string _no = txtno.Text; int _sum=0; for (int i = 0; i { if (_no[i].ToString() == 
 || _no[i].ToString() == ||_no[i].ToString()== ) { //Do Nothing } else { lst.Add(int.Parse(_no[i].ToString())); } } foreach (int item in lst) { _sum += item; } txtsum.Text = _sum.ToString();
