Introduction To C# Keywords
The following article provides an outline for C# Keywords. Keywords are a set of specific words used in programming languages that are pre-defined in nature and are also unique in nature. Each keyword has its own definition and purpose which can be used in several places of a programming sequence as and when required depending upon its necessity. These are generally reserved in nature and have been created in that pattern by the developers of the programming languages to serve a pre-defined purpose.
The keywords used in these programming languages are somewhat similar in nature whether it is C , Java or C# in .NET Framework as they were made with previously inscribed meanings and the same intent to serve their purpose although on separate platforms.
Keywords In Programming Language
Given below are the keywords in any programming language:
- Keywords in any programming language are a set of words like main, if, while, for, else, int, long and etc.
- These keywords being reserved words can be used only for a specific purpose for which it was built.
- Keywords implement specific characteristics of the programming languages only.
- They cannot be used as a user-defined identifier as they are already pre-defined in nature.
- Different programming languages have their own specific keywords set.
- Keywords in programming languages also cannot be used to name variables or even objects as they were made static in nature with a specific purpose and they being used for a different purpose will cause an error in programming sequences.
Types Of Keywords In C#
There are different types of keywords in C# depending upon the type of functions it has and the type of operations it needs to perform.
The main keyword types of C# are:
- Modifier Keywords
- Access Modifier Keywords
- Statement Keywords
- Method Parameter Keywords
- Namespace Keywords
- Operator Keywords
- Access Keywords
- Literal Keywords
- Type Keywords
- Contextual Keywords
- Query Keywords
Each of these keyword types serves a specific purpose in C# programming performing a set of task unique to itself and pre-intended. These keyword types contain several specific keywords each with its own definition and are used as and when required during the programming sequences. Some glimpses of such keywords are new, static, public, protected, switch, in, while, return, checked, do-while, out, sizeof, new, null, void, char, string, int, decimal, short, dynamic, set, join, where and several others.
Examples Of Various Keywords In C#
We have classified each of the keywords in a specific type as per their meaning and requirements in C# programming. Each of these keywords is pre-defined and is used accordingly when they are required by the programmers during their coding sequences.
Below table shows the classifications and their grouping types:
| Keyword Types Of C# | |
| Keyword Types | Keywords |
| Modifier | Abstract, const, event, extern, new, override, partial, sealed, static, virtual and volatile |
| Access Modifier | Public, private, internal and protected |
| Statement | If, else, switch, case, do, for, for each, while, break, default, continue, try, checked, unchecked, goto and return |
| Method Parameter | Params, ref and out |
| Namespace | Using, dot operator, :: operator and extern |
| Operator | Is, new, sizeof, typeof and stackalloc |
| Literal | Null, false, true, value and void |
| Type | Byte, char, class, decimal, enum, double, int, long, short, string and struct |
| Contextual | Add, var, dynamic, global, set and value |
| Query | From, where, select, join, orderby, let, in, equals, ascending and descending |
Conclusion
Thus, after the discussions above we can surmise that keywords are a very important and crucial component of all programming languages and also C# programming language itself. These keywords play a vital role in shaping almost all types of programs in the programming world into a meaningful and structured form. Due to their specific nature of being pre-defined and static, they can be easily used by the programmers to write long & several lines of code smoothly and easily without any risks and errors. In a nutshell, we can say that the keyword acts as a vital backbone for the entire programming universe.
