2.loc_proc\pkg\cnss_proc\bin

namespace aputloader
{
    class Program
    {
        static void Main(string[] args)
        {
            string buildlocation = @"\\location\builds784\INTEGRATION\LOC.1.2-00028-Z-1";
            //check if atleast one of the following folders exist and append to buildlocation

            //1.BIN-LOC-WiFi-FW\loc_proc\bin

Answer 1

Maybe something like this?

if(Directory.Exists("BIN-LOC-WiFi-FW\loc_proc\bin")) 
{
    // This path is a directory

}
else if(Directory.Exists("loc_proc\pkg\cnss_proc\bin")) 
{
    // This path is a directory

}
else if(Directory.Exists("loc_proc_ps\package") 
{
    // This path is a directory

}
else 
{
    Console.WriteLine("No valid folder exists.");
    // Do nothing.
}
