This is VERY unclear!
do you:
1) want to extract the middle number (month?) from the string
2) want the first digit of the third number (year?)
Use "Improve question" to clarify.

So it's ain't a string but a date! Use it as a date and you will got the tool to extract the month...

If it really is a string then:

C#

string a="31/2/2014";
string[] parts = a.Split('/');
if (parts.Length >= 2)
{
  return parts[1];    // and parts[0] has the day and parts[2] has the year
}
else
  // bad input

If it really is a DateTime then:

C#

DateTime dt = new DateTime(2014, 2, 31);
int month = dt.Month;

There are quite a few ways you could do that:
1) string.Substring - easy... Just give it the offset and length and it'll do it.
2) regex - a bit more complex, you set up as pattern that extracts the month without needing to know the offsets, because it can cope with variable length day and month numbers.
3) convert it to a DateTime and extract the month from that.

The last is pretty easy: just use DateTime.Parse of the string, and then access the DateTime properties to get your month.

Me? I'd go with the DateTime every time!
