Parsing data

Hello everyone,

So im parsing TLE data, for instance i got a line: "88109B", "88" means that the satellite was de-orbited at 1988. How can i write a short program that would change the first two characters to given date.
Also if the string is something like this:"05108B", it means that the satellite was de-orbited at 2005, not 1905.

Can anyone help me?

Thanks alot !

 

Code (csharp):

1.  
2. public static int ParseYearTLE(string data)
3. {
4.     int inCentury;
5.     if (int.TryParse(data.Substring(0, 2), out inCentury))
6.     {
7.         if (inCentury < 0) return -1;
8.         int century = inCentury <= 19 ? 20 : 19; // Up to 19 assume the 20th century, else the 19th century
9.         int year = 100 * century + inCentury;
10.         return year;
11.     }
12.     return -1;
13. }
14.  

This would return the year as int. You could change that to a DateTime, but that seems more specific than the data contains. If there is a parsing error, it will return -1.

 

Thank you!
