how to pass Enum

[kjqua]

Hi all,

I am newbie in c# and i have a question.

I try to work with serial port.
and i will like to configure the serial port by a form

I add in a ComboBox.parity some items like:
None
Odd
Even
Mark
Space

then i will like to pass the item value to serialPort.pari ty
serialPort.pari ty = cmbParity.Selec tedItem
how can i do ?

thanks
Marco

You can convert text into enum values using the static method Enum.Parse:

serialPort.pari ty = Enum.Parse(type of(System.IO.Po rts.Parity),
cmbParity.Selec tedItem);

Enum.Parse returns object, you still need a cast:

serialPort.Pari ty =
(System.IO.Port s.Parity)Enum.P arse(typeof(Sys tem.IO.Ports.Pa rity),
cmbParity.Selec tedItem);

Hi,
I try both code but they don't work
i have this message error
The best overloaded method match for 'System.Enum.Pa rse(System.Type ,
string)' has some invalid arguments
Argument '2': cannot convert from 'object' to 'string'

So cast cmbParity.Selec tedItem to a string in the call...

Thanks now it work
serialPort.Pari ty =
(System.IO.Port s.Parity)Enum.P arse(typeof(Sys tem.IO.Ports.Pa rity),
cmbParity.Selec tedItem.ToStrin g());
