Return Cookie =   Null   | Cookie. Value =   Null   | Cookie. value. Trim (). Length =   0 ;
}

Public   Static   Int Parseint ( This Httpcookie)
{
Int Tmpint;
Return   ! Cookie. isnullortrimempty () && Int32.tryparse (cookie. value. Trim (), Out Tmpint) ? Tmpint: - 1 ;
}

{
IntTmpint;
ReturnInt32.tryparse (strvalue,OutTmpint)?Tmpint:-1;
}
