If condtion does not executed using C# in ASP.Net

I have cross checked the code it is working.

string Fromses = "f", from = "f", todes = "t", to = "t";
string seatno = "1,2,3";
if (Fromses == from && todes == to)
{
    string[] arr = seatno.Split(',');
    for (int i = 0; i < arr.Length - 1; i++)
    {

    }
}
