Enum
C# is a wonderful language for modern programming. While everything in C# has a reason and a place, occasionally there are things that can be confusing for a developer who isn’t aware of what is happening behind the scenes. This is another post in the Little Pitfalls series where I explore these issues; an index of the Little Wonders and Little Pitfalls posts is here. Many times, we create overloaded methods or constructors to allow them to accept different kinds of data. Further, there are times ...
Once again lets dive into the Little Wonders of .NET, those small things in the .NET languages and BCL classes that make development easier by increasing readability, maintainability, and/or performance. So probably every one of us has used an enumerated type at one time or another in a C# program. The enumerated types we create are a great way to represent that a value can be one of a set of discrete values (or a combination of those values in the case of bit flags). But the power of enum types ...
Two posts ago, I talked about the C# enum and some of its pitfalls (here). This post continues with a discussion of the fundamentals of enums by continuing with using enums and bit-flags. Defining a [Flags] Enum Now, we’ve seen previously that enums are typically used when you want to represent a type that can be one of a distinct set of values. But they can also be used to store a combination of discrete values. That is, the standard use of an enumeration is to support mutex options - such as an ...
Continuing on the same vein as my last topic where I discussed differences between C# const and readonly keywords (here) and their uses, today I’m going to look at C# enums and their pitfalls. I will only be discussing the basic enums today (the post got kind of long so I’ll discuss enums marked with the [Flags] attribute next post). Quick Recap of Enums First, a quick recap of enums for those who are brand new or less familiar with them. Basically, enums a great way to declare a variable of a type ...
