       szAlarmTime;
  }

public void CB_SubscribeEvent(PLAT_SUBSCRIBE_EVENT_V20 pstEvent, IntPtr pUser)
{
           byte[] _szAlarmTime = Encoding.Default.GetBytes(pstEvent.szAlarmTime);
            string __szAlarmTime = Encoding.Default.GetString(ar);
}

but  __szAlarmTime = \0\0\0\0\0\0\0\0??;\b\0\0\0\0?????qUw?g?\u0001\0\0\0\0"

\0\0\0\0\0\0\0\0??;\b\0\0\0\0?????qUw?g?\u0001\0\0\0\0 its not humman readable data.

Looks OK to me. What makes you think it's wrong?

Your code does not make sense. You have three versions of the string: __szAlarmTime, _szAlarmTime and szAlarmTime. But you are not explaining where these strings come from, or what they are supposed to represent. Please update your question with more detail.

The chances are that the conversion is working perfectly - but the input is not what you expected, so the output doesn't look like a "readable string". I'd start by looking at where you get the pst.Event.szAlarmTime from and look at the definition in any documentation with that. The chances are that it's not a human readable alarm time at all, but an encoded DateTime start, a repeat value and / or an end value which you will need to process in much better detail to get a human readable value from.
