C#

 List<string> stringList = new List<string>();
 stringList.AddRange(new string[] { "1", "2", "3", "4", "sdfsf", "7" }); // for illustration
 int temp;
 var yourIntegerList = stringList.Select(x => int.TryParse(x, out temp) ? int.Parse(x) : -1).ToList(); // -1 used here, can be any integer
var  Finallylist = yourIntegerList.Where(a => a != -1).ToList();

foreach (var item in Finallylist)
{
    Console.WriteLine(item);
}
Console.ReadKey();

output:

only Integers from the list.

Solution 3

C#

int value;
char c;

string input = Console.ReadLine();
if (int.TryParse(input, out value))
{
    c = (char)('a' + value - 1);
    Console.WriteLine("{0}", c);
}
else
{
    c = input.ToLower()[0];
    value = c - 'a' + 1;
    Console.WriteLine("{0:00}", value);
}
