C# enum get friendly name
If you develop using C and the. Net ecosystem, chances are that you will need to use enums at a certain point. The enum keyword is used to declare an enumeration, a distinct type that consists of a set of named constants called the enumerator list. I put 0, 1, 2 as comments just to point out that enums are by default of type int. However, there might be a small challenge. So how to solve that?SEE VIDEO BY TOPIC: 12.

Smart enums / Type-safe enums in .NET
Sanity Free Coding Methods to the Madness. NET enums are a strongly typed flag-like object. Flags would normally defined as a macro, or constant variable. The trouble with typical numeric flags is that a the coder using the flag may or may not know all of the possible values, or b might accidentally type the wrong constant or macro. Since the flag is just some magic number they may end up with a logic error that may be hard to find under certain circumstances.
With enums I can provide the same logic some numeric flag but create a type that I can use to enforce some subset of numbers that are checked at compile time, and can be verified at run time Enum. As with everything, enums have their faults. What if I want to extend some enum object polymorphic enums? Yesterday at work we ran across a case where being able to extend an enum was mandatory.
ToString Our company uses code generation like most fish use water. Since our code is generated, if we go in and manually add additional values that don't need to be stored in the database, our generation tool will blow away any hand written changes on every build. We would have killed to have something like a partial enum, but alas, no such thing exists. I set out to try to create a "Fake Enum" class that acted and felt like an enum but allowed us to extend it by way of the partial class or inheritance.
Well after a little poking around, inheritance flew out the window just over complex without resorting to some generics base type , but the ability to do a partial fake enum was definitely doable. Here's the code I came up with: using System; using System. ComponentModel; using System. Globalization using System. Reflection; [ TypeConverter typeof FakeEnum.
GetFields BindingFlags. Static BindingFlags. Public BindingFlags. FlattenHierarchy BindingFlags. GetValue null as FakeEnum ; if enumValue! Compare field. Compare staticField. ReferenceEquals a, null return false ; return a.
ReferenceEquals a, null return true ; return! It made it look a bit more "enum" like. WriteLine flag. Since I had full control over the type, I decided it would be nice to add the FriendlyNameAttribute functionality into my fake enum, so I did. Its implementation uses. My GitHub Code.

EnumHelper - Getting a Friendly Description from an Enum
Comment 0. The Java Enum has two methods that retrieve that value of an enum constant, name and toString. The toString method calls the name method, which returns the string representation of the enum constant. In listing 1, the value returned by calling the name and toString on an Animal.

C# stuff nobody told you – enum is a b*tch!
In my previous article, we have learned that how to bind combobox directly with enum. In my previous article , we learned how to bind a combobox directly with the enum. So here, we will learn a way to show user-friendly enum names to end users. Please note that here, I have considered the implementation mentioned in the previous article, so please check that first before going further. Now, we will implement IValueConverter to display enum description instead of enum value. For that, create a class called EnumDescriptionConverter as mentioned below. We are going to use this converter with binding.
Creating user friendly strings for C# enums
Buy the print C 5. See inside the book for access code and details. While giving you those insights, you learn where and how to use the features to design various kinds of software. NET platform as a whole. The early chapters introduce the.
Here: In this example, an int is provided with the value 3 and the correct MedicationType is returned. Tip: The typeof operator invokes reflection and the Enum. GetNames method also internally accesses the metadata representation in memory.
C# Enum.GetName, GetNames: Get String Array From Enum
An Enumeration or enum is a data type that includes a set of named values called elements or members. The enumerator names are usually identifiers that behave as constants in the language. Sometimes you might need to loop on the elements of a particular enum and print its element names, however as you know by the language constraints, the enum element names must follow the naming convention, you cannot include spaces or other special characters. Therefore printing the elements will lead to printing the defined non-friendly elements names.
Sanity Free Coding Methods to the Madness. NET enums are a strongly typed flag-like object. Flags would normally defined as a macro, or constant variable. The trouble with typical numeric flags is that a the coder using the flag may or may not know all of the possible values, or b might accidentally type the wrong constant or macro.

How to Display Friendly Names for Enumerations in C#?
Wherever possible we use enumerations in our applications. Often the name of the enumeration isn't what you want to print on the screen. It could be because the enumeration is 2 words that have been joined together, or you want the description to start with a number not that we do this You might have a enumeration for Colours that a user is allowed to select from. The values available for this enumeration may be hypothetically :.
