Recall from my previous article, when we said that every language consists of keywords and that these keywords are only understandable by the people who speak the language.
The same is with C#; keywords are special words that have special meaning in the C# language and are reserved by the language. That last sentence has significant meaning, so I will take about it a little later on.
To explain what a keyword is, let’s go back to our own language: English. When I write “Hello”, it’s actually a keyword in the English language. We use it when we want to greet someone. Much like “Hello”, each of the keywords in figure 2.1 means something that you and the compiler will understand. As we continue, you will learn more about these keywords and how to use them inside your code to form a program.
One of VS.Net’s features is coloring the keywords blue so you can easily identify them in C# code.
