C#

this is the code I got and it works unless you abbreviate days mon tue etc this is the string
string sPattern = "^(Mon|(T(ues|hurs))|Fri)(day|\\.)?$|Wed(\\.|nesday)?$|T((ue?)|(hu?r?))\\.?$";
how can I modify the string to just Monday Tuesday etc?

public static void Main()
{
    string[] names = { "Omar", "-232" , "Don" , "Test"};
    string theSelected = string.Join(" " , names);

    Console.WriteLine("The Avilable names are : " + theSelected);
    Console.WriteLine("Which name you need ? ");
point: string Selected = Console.ReadLine();
    string[] first = Array.FindAll(names, namess => namess.ToLower().StartsWith(Selected.ToLower(), StringComparison.Ordinal));
    int i = 4;
   if (!(Selected == "") && !(Selected.StartsWith(" ")))
    {
        if (theSelected.ToLower().Contains(Selected.ToLower()))
        {
            Console.WriteLine("The names start with " + Selected.ToUpper() + " is / are : \n" + string.Join("\n", first));
        }
        else
        {
            Console.WriteLine("The names start with " + Selected + " is / are : \nNone");

        }
    }
    else
    {
        Console.WriteLine("The Avilable names are : " + theSelected);
        goto point;
    }
    Console.ReadKey();
}
