Trying to declare a enum datatype.
Below works
Public Enum EnumCharSet
IBM037
IBM437
IBM500
End Enum
When I add a new string with a "-", error occur says that "End of statement
expected"
For example
Public Enum EnumCharSet
IBM037
IBM437
IBM500
ASMO-708
End Enum
Does not work because ASMO-708 has a "-" there.
What went wrong and what should I do?

Notice that each named item in the enumeration is not enclosed in quotes.
Enumerated names are not strings; they're actually constants. If you look
at the IL of an enumeration, you'll see that your Enum is actually a class
that derives from System.Enum. Each name in the Enum becomes a Public Const
field of the class.
Because the names are not strings, the dash is interpreted as a minus sign
which is an illegal character in a type or variable name.

Basically, each enum value must follow the same naming constraints that any
varaible (symbol) would have.

Thanks for all your replies, problem sloved now. it is better to use a class
in this situation.
Enumerations really boil down to syntactical convenience. Have you
considered using a Hashtable instead?

Hello all,
I have a question about enumerations. Within some requirements data
passed back a certain bit field is defined by three bits then in
another section the bit field is defined as 4 bits. The second set is
a superset of the first set. The enumeration look as following...
enum SET1 { AutoOffState = 0x00, AutoOneState = 0x01,
TrippedOffState = 0x02, TrippedOnState = 0x03,
LockedOffState = 0x04, LockedOnState = 0x05,

Hello,
In VS2003, I tried using an enum and setting it into a field in a
datarow. It seems as if the datatype of the field in the row
determined what went into the field. If the datatype was string, then
the name of the enum item went into the field, but if the datatype was
integer, then the integer value of the enum was stored.
Is this expected behaviour? I couldn't find anything while searching
for answers.

So I was needing some extra power from my enums and implemented the
typesafe enum pattern.
And it got me to thinking... why should I EVER use standard enums?
There's now a nice little code snippet that I wrote today that gives me
an instant implementation of the pattern. I could easily just always
use such an implementation instead of a standard enum, so I wanted to
know what you experts all thought.
Is there a case for standard enums?

Imagine you have a charting library that can draw lines, bars,

Lines and bars need only one input. Floating bars and bands need two
inputs. There are two approaches:
1) One enum with all 4 types (bars, band, etc). One chart class that
accepts up to 2 arrays of values. If the user choses a band but there
is only one input array throw an exception. If the user passes two
input arrays with different lengths throw...

The documentation for the "is" keyword says:
An is expression evaluates to true if the provided expression is
non-null, and the provided object can be cast to the provided type
without causing an exception to be thrown.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
