Any Advantage To Prefixing Enum Values?
Mar 24, 2011
In this post Jon Skeet pointed out that the following code should be changed to conform with the .NET naming conventions. Doing that would also decrease the amount of noise in the code.
[Code]...
I must admit, I was pretty much like a sheep and was following what others have done before me. I thought the prefix did not look right and then to have it twice did not make sense either. After looking at a couple of .NET Framework examples, it looks like this would be closer to the standard.

For Each fsr As String In [Enum].GetNames(FSRS)

I don't know how to convert the following line from VB to C#:
Dim values As New List(Of T)(System.Enum.GetValues(GetType(T)))
My version doesn't work:
List<T> values = new List<T>(System.Enum.GetValues(typeof(T)));
The best overloaded method match for 'System.Collections.Generic.List.List(System.Collections.Generic.IEnumerable)'
has some invalid arguments
The constructor-parameter doesn't take it that way - what cast (or else) am I missing?
For clarification: It is wrapped up within the following generic method
public static void BindToEnum<T>()
{
List<T> values = new List<T>(System.Enum.GetValues(typeof(T)));
//...
}

In VS2008, you could write, for instance,
dim enumValue as MyEnum
enumValue =
And then as soon as you typed the =, you'd get a list of possible values of MyEnum. With VS2010, you have to type
dim enumValue as MyEnum
enumValue = MyEnum.
Before getting the list on typing the final. This makes for a lot more typing and seems to be a retrograde step ... is there an option I'm missing? (I have 'Auto List members checked in the Text Editor options under 'Basic').

I'm trying to declare an enumeration and one of the names I'd like to use for an item is not usable apparently. Where I am declaring 'STEP = 3', I get this error message in visual studio: "Statement cannot appear within an Enum body. End of statement expected." Is it possible to use STEP as an item name somehow? [Code]

Which is better, using a nullable enum or adding the value None=0 to your enum list?Using nullables requires more code, but I kind of like it since it forces me to think about the possibility. Otherwise I'm liable to forget about the None enum and fail to account for it being a special case.

im considering to study properly 1 of these two languages because in vb.net the limitations ive encountered were not very significant, and C# because i hear all ppl shouting at how vb express is for newbs and how C# is the way to go..What i would like to ask is, what is exactly the main advantage of C# over VB Express because what ive read from wikipedia, the only difference is the language, while C# might have 1 thing or 2 extra to vb express and vice versa...[URL]..So, could anyone clear me up please? i would really like to know if vb express is really worse than C# or the differences are only in syntaxes.
I personally used to hate VB Express at the begining but now im fastly changing my mind so im more inclined to this language, but i dont wanna wake up in 3 years realising ive been wasting so much time in a language that isnt as good as "the competition", get it?

I have the following class:

Property MyInteger as Integer
Set(ByVal value as Integer)
_MyInteger = value
[code]....
As I'm not using any validation etc in my Property, is there any advantage of using a Property in this case, or would it be neater to use:
Class MyClass
Public MyInteger as Integer
End Class

What's the advantage of declaring a function as "Shared"? I've noticed that it doesn't require you to instantiate an object to use the method when it declared as "Shared". Is that the only upside?

These two snippets do the same thing - is there one that's better than the other, or is it just a matter of preference?

I was wondering if there is any advantage to do everything programmatically instead of using design view to create forms, controls etc. Would there be any difference in size and/or performance after you compile it? So far I've been doing pretty much everything programmatically, specifying all the properties that aren't default for my forms controls but I am starting to wonder is there are any advantages to this, apart from making it easier (sometime) to manage and change the behavior of my controls.
