Hi Please try like this
String text = txtbx.Text;
String[] parts = text.Split(new Char[] { ',', ':', ';', '-', '_' }, StringSplitOptions.RemoveEmptyEntries);
int temp = 0;
foreach (String item in parts)

Vulpes · Answer

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 =49&&_no[i]<=57)//Check on ascii
{
lst.Add(int.Parse(_no[i].ToString()));
}
}
foreach (int item in lst)
{
_sum += item;
}
txtsum.Text = _sum.ToString();

Krishna Garad · Answer

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 < _no.Length; 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();
