Enumerated types and string type conversion

1. enumeration switch string, with .ToString ()

enum QQstate : short
{
      Online = 1,
      Offline,
      Hidden = 5,
      Leave,
      Busy
 }
QQstate state = QQstate.Online;
Console.WriteLine(state.ToString());

2. String transfer other types: Type target .Parse ()

string str = "123";
int myInt = int.Parse(str);

3. String enumeration with that Enum.Parse switch (), parameters need to pass a certain type, a type with typeof, then turn strong

enum QQstate : short
{
      Online = 1,
      Offline,
      Hidden = 5,
      Leave,
      Busy
 }
QQstate state1 =(QQstate) Enum.Parse(typeof(QQstate), "1");
Console.WriteLine(state1);        // Online
