Ennumerate definution

Ian Johnston — Mon, 14 Jun 2010 22:02:45 GMT

I am trying to build an enum of baud rates to populate a drop down list.

public enum BaudRateVal

{

1200,

2400,

4800,

9600,

19200,

38400,

57600,

115200,

230400

}

Gives an error "Identifier expected", what is missing?

Thanks both of You, went the table route.

As Charles has stated, in C#, an identifier must start with either a letter or an underscore. So, you have some options:

1. Use an enum, change name to something like "Baud1200" or "_1200".
2. Use enum, name as above but add the EnumDisplayValue attribute to the enum items to explicitly provide the display value. This is in MicroFour.StrataFrame.Tools namespace.

[codesnippet]using MicroFour.StataFrame.Tools;
public enum BaudRateVal
{
  [EnumDisplayValue("1200")]
  Baud1200,

  [EnumDisplayValue("2400")]
  Baud2400,

  [EnumDisplayValue("4800")]
  Baud4800,

  [EnumDisplayValue("9600")]
  Baud9600,

  [EnumDisplayValue("19200")]
  Baud19200,

  [EnumDisplayValue("38400")]
  Baud38400,

  [EnumDisplayValue("57600")]
  Baud57600,

  [EnumDisplayValue("115200")]
  Baud115200,

  [EnumDisplayValue("230400")]
  Baud230400
}[/codesnippet]

3. Add a table with the Baud rates, then fill the combo with a BO instead of an enum.

Hope that helped!

Since an enum is itself an integer it is not going to accept and integer as a "string"

It will accept

Baud1200
Baud2400
etc

but doesn't seem to like

1200Baud
2400Baud

etc.

You probably would be better off just creating a dropdownlist combobox and explicitly filling in the items collection.

Seems you'd be better off storing the baud rate as string anyway. Kind of like a phone or zipcode - all numbers but not really used that way.
