For this int has the value of "19971998". I really wanted to split this value into like this "1997 - 1998"??
int index = Convert.ToInt32(radioListBox1.SelectedIndex);
string indexvalue = Convert.ToString(this.radioListBox1.Items[index]);
string input = Regex.Replace(indexvalue, "[^0-9]+", string.Empty);
MessageBox.Show(input);
you can write like:
int index = Convert.ToInt32(radioListBox1.SelectedIndex);
string indexvalue = Convert.ToString(this.radioListBox1.Items[index]);
string input = Regex.Replace(indexvalue, ".{4}", "$0-");
MessageBox.Show(input);
var s = "19971998";
String.Format("{0}-{1}", s.Substring(0,4), s.Substring(4, 4)));
To make it work with Regex
you'd need to do the following:
string input = Regex.Replace(indexvalue, "^(.{4})", "$1-");
But as someone suggested, it may be even easier to do this one.
string input = indexvalue.Insert(4, "-");
int index = Convert.ToInt32(radioListBox1.SelectedIndex);
string indexvalue = Convert.ToString(this.radioListBox1.Items[index]);
string input = Regex.Replace(indexvalue, "[^0-9]+", string.Empty);
The problem was solved, this was missing my code.
if (input.Length == 8) input = input.Insert(4, " - ");
MessageBox.Show(input);
