Merci!

Venu, the old proverb says that it's better to teach a man to fish than to simply give him a fish, so I'm going to point you at an automated conversion tool from C# to VB:

Simply copy and paste the code above into the tool, and you'll get the C# equivalent. Cool, isn't it?

You can get the string values of enums also by calling Enum.GetNames or Enum.GetName...

The problem occurs when the Enum definition is made of multiple words.

Another more flexible approach (albeit much slower) is to adhorn each Enum value with a DescriptionAttribute, and to use reflection to grab that

Very helpful - Thanks!

Can I get this in COBOL, 8088 assembly, and Pascal too? No hurry, I need it by next Wednesday.

Thanks again!

Hi, i was just wondering if you knew how I could do this exact thing in C++.NET? I have found so many C# examples but they all seem so different to what I am used to.

Many thanks,

John

Well here's a small example using managed C++:

namespace EnumMagic
{
public __gc class MagicSet
{
public:
__value enum MagicItems
{
WAND
, POINTY_HAT
, RABBIT
, SCARF
, PLAYING_CARDS
, PIDGEON
};
};
}

int _tmain()
{
String* aNewEnumString = __box( EnumMagic::MagicSet::PLAYING_CARDS )->ToString();

EnumMagic::MagicSet* aNewMagicSet = new EnumMagic::MagicSet();

if ( Enum::IsDefined( __typeof( EnumMagic::MagicSet::MagicItems ), S"RABBIT" ) )
{
aNewMagicSet =
static_cast< EnumMagic::MagicSet* >( Enum::Parse( __typeof( EnumMagic::MagicSet::MagicItems ), S"RABBIT" ) );
}

if ( Enum::IsDefined( __typeof( EnumMagic::MagicSet::MagicItems ), S"PRETTY_ASSISTANT" ) )
{
aNewMagicSet =
static_cast< EnumMagic::MagicSet* >( Enum::Parse( __typeof( EnumMagic::MagicSet::MagicItems ), S"PRETTY_ASSISTANT" ) );
}

return 0;
}

The C# to VB.NET is great, but what about just plain VB or VBA?

Hi Tim:
I wonder, if this can work in my situation.
I have a switch statement:
switch (moduleName)
{
case "Module1" : return 1; break;
case "Module2" : reutrn 2; break;
}

I have also an enum:
public enum ModuleNames
{
Module1,
Module2
}

So is there a possibility I can substitute the "Module1", "Module2" in my switch with something like

case ModuleNames.Module1: ....

Also, in your line:
Colour c = (Colour) Enum.Parse(typeof(Colour), "Red", true);
Console.WriteLine("Colour Value: {0}", c.ToString());

Why do we need to do so? I mean c.ToString() doesn't have the value of "Red"? So we already have it, Am I missing something?

Thanks,

Thank you,
it is a shame that enum_type written does not inherit capabilities of base enum.
