C#

string s = "1.2.3.4";
string[] parts = s.Split('.');
foreach (string part in parts)
   {
   Console.WriteLine(part);
   }

A more complex way to deal with this is to use a 'SortedDictionary with a custom Comparer: the example shown here exploits the fact that numeric character sequences not at the end of the string are sorted in the order you want; only when the numeric characters are at the start of the string, do you need to compare in "reverse."

Thanks for your reply but I did the same before, but did not receive any response

Thanks for your cooperation friends. But I find myself sharing the reason that other friends, if they can find this problem, can use grammar code in this way (or in your program). Saman from Iran

A lot of books deal with the console side of c# more than the form side.

MessageBox.Show("The Yes button was clicked", "My form event handler", MessageBoxButtons.OK, MessageBoxIcon.Information);

private void YesButton_Click(object sender, EventArgs e)
    {
    MessageBox.Show("The Yes button was clicked", "My form event handler", MessageBoxButtons.OK, MessageBoxIcon.Information);
    }

private           So that it is only usable inside the form.
void              Because it doesn't return a value
YesButton_Click   Name of the handler method: YesButton Click event
object sender     "sender" is object that raised the event (useful if several buttons share the same handler)
EventArgs e       Provides extra information on the event if you need it.
