The C# .NET language has constants, and it has variables. A constant is essentially a value that is known at compile-time, whereas a variable is essentially a placeholder of a specific type for a value that can change at runtime. An enum is a bit of an anomaly because it defines a type with unique set of elements backed by an integer type . . .

I have previously written an article on extensions methods, which included some information about using generics with extension methods. Since that time, I have stumbled across something I did not previously realize:

If the compiler can figure out the generic type from one of the parameters passed into the extension method, you do not have . . .

There are numerous ways to accomplish data synchronization in .NET and C#, such as the commonly used System.Threading.Monitor .NET Framework class and corresponding C# lock statement. But, when it comes to super-fast synchronization, nothing beats the . . .

October 23, 2015

Every once in awhile, the need seems to arise to create a method that takes a large number of boolean arguments. The method prototype would like something like the one shown below.
