 如果（DateTime.Now.AddHours（24）＆LT; = passwordLastSet）
 

应

 如果（DateTime.Now＆LT; = passwordLastSet.AddHours（24））
 

I have a method that queries active directory, and returns the value of the Last Password Reset to a local variable. I am trying to compare that value to the current date and time, and check if it's been less than 24 hours. I think I'm close, but can't seem to get this to work.

Thanks, Jason

string passwordLastSet = string.Empty;
passwordLastSet = DateTime.FromFileTime((Int64)(result.Properties["PwdLastSet"][0])).ToString();  
public string lastReset(DateTime pwordLastReset)
    {
        if (DateTime.Now.AddHours(24) <= passwordLastSet)
        {
            return "try again later";
        }
        else
        {
            return "all is good";
        }

    }

This:

 if (DateTime.Now.AddHours(24) <= passwordLastSet)

should be

   if (DateTime.Now <= passwordLastSet.AddHours(24))
