Hi, I have the following enumerator: public enum AuthenticationMethod { FORMS = 1, WINDOWSAUTHENTICATION = 2, SINGLESIGNON = 3 } The problem however is that I need the word "FORMS" when I ask for AuthenticationMethod.FORMS and not the id 1. I have found the following solution for this problem: First I need to create a custom at...
If I use /clr:oldSyntax the following should work: public __value enum IceCreamFlavors { Vanilla, Chocolate, Sardine, }; what is the equivalent in non-oldSyntax? How do I declare a "managed" enum in Managed C++ for .NET 2.0? Edit: when I follow JaredPar's advice, then if I try to pass an IceCreamFlavor to a function with the...
Given an enum that has assigned values, what is the best way to get the next or previous enum given a value. For example, consider this enum: public enum TimeframeType { None = 0, [Description("1 month")] Now = 30, [Description("1-3 months")] Short = 90, [Description("3-6 months")] Medium = 180, [Descript...
This has always bugged me. Perhaps someone with some hardcore knowledge of .NET internals can explain it to me. Suppose I define an enum as follows: public enum Foo { Eenie = 1, Meenie = 2, Miney = 3, Moe = 4 } Now, also suppose that somewhere in my code, I have the following code: int bar = (Foo)5; This will compile j...
using declaration does not seem to work with enum type class Sample{ public: enum Colour { RED,BLUE,GREEN}; } using Sample::Colour; does not work!! do we need to add using declaration for every enumerators of enum type? like below using sample::Colour::RED; ...
I am having trouble sending a collection of Enums to a WCF service method. I used this post as a guide: Sharing Enum with WCF Service [ServiceContract] [ServiceKnownType(typeof(MyEnum))] [ServiceKnownType(typeof(List<MyEnum>))] public interface IMyService{ [OperationContract] MyEnum ServiceMethod1( ); [OperationContract] ...
I have a lot of fixed-size collections of numbers where each entry can be accessed with a constant. Naturally this seems to point to arrays and enums: enum StatType { Foo = 0, Bar // ... } float[] stats = new float[...]; stats[StatType.Foo] = 1.23f; The problem with this is of course that you cannot use an enum to index a...
Why can't enum's constructor access static fields and methods? This is perfectly valid with a class, but is not allowed with an enum. What I'm trying to do is store my enum instances in a static Map. Consider this example code which allows lookup by abbreivation: public enum Day { Sunday("Sun"), Monday("Mon"), Tuesday("Tue"), Wedne...
We have a smelly code in our project. A lot of values which used in biz logic have 2 places where they stored: we have dictionary tables (used in FK relations) in DB where we stored values e.x. MessageDirectionInfo: 0|Unknown 1|In 2|Out and we have Enum with exactly same data: MessageDirectionEnum{Unknown=0,In=1,Out=2} And all over ...
I am writing a web service in Java, and I am trying to figure out the best way to define error codes and their associated error strings. I need to have a numerical error code and an error string grouped together. Both the error code and error string will be sent to the client accessing the web service. For example, when a SQLException oc...
I'm using IIS/asmx to support a Flash client. Some of my service layer data transfer objects have properties that are enumeration values. There are cases where these properties should be null. When an object with a null value for such an enumeration property is rendered to soap, I receive this error: System.InvalidOperationExceptio...
I have a really strange enum bug in Java. for(Answer ans : assessmentResult.getAnswersAsList()) { //originally stored in a table //AnswerStatus stat = ans.getStatus(); if (ans.getStatus() == AnswerStatus.NOT_ASSESSED) { assessed = false; } } An answer is an answer to a question on a test. An assessment result is th...
Hi, I have an enum which is used by multiple classes. What is the best way to implement this? Thnx ...
I have an class which has a enum property and a boolean property, based on that it calls a specific method with specific parameters. I use a switch statement for the enum and an if for the boolean within each case of the switch. It is a long list and doesn't feel to me to be the most elegant solution. Anyone got a more elegant or simpler...
I've been programming in Java for a while and just got thrown onto a project that's written entirely in C#. I'm trying to come up to speed in C#, and noticed enums used in several places in my new project, but at first glance, C#'s enums seem to be more simplistic than the Java 1.5+ implementation. Can anyone enumerate the differences ...
Does Perl have an enumeration type that adheres to best practices, or maybe more importantly, does it need one? The project I am working one uses strings all over the place to denote things that would typically use an Enum in a language like C#. For example, we have a set of phone numbers in an array of hashes, each associated with a p...
Hi folks, after a bit speedtracing I found a piece of code (called very very often) which converts values of one enum to values of another enum, like this: public Enum2 ConvertToEnum2(Enum1 enum1) { switch(enum1) { case Enum1.One: return Enum2.One; break; case Enum1.Two: return Enum2.Two; ...
How do I do a simple compare of an enum value and a string that should match the enums name? How do I parse the string into it's appropriate enum value. For example, Enum A B=0 C=1 D=2 End Enum How do I check if String = A.C and how do I convert string into its corresponding A value without comparing it to a string re...
It is possible to add and remove elements from an enum in Java at runtime? For example, could I read in the labels and constructor arguments of an enum from a file? @saua, it's just a question of whether it can be done out of interest really. I was hoping there'd be some neat way of altering the running bytecode, maybe using BCEL or ...
My enum consists of the following values: private enum PublishStatusses{ NotCompleted, Completed, Error }; I want to be able to output these values in a user friendly way though. In this SO post, there is a lot of code that I can't seem to compile.. I don't need to be able to go from string to value again. Why is it not compiling a...
