Single line comment in C#. In this program we can learn how to include the single line comments in C sharp. Comments can be used to explain and improve the readability of C# code. When evaluating alternative code, it can also be used to prevent execution. Two forward slashes (//) begin single-line comments. C# ignores any text between / and the end of the line (will not be executed).
static void Main(string args)
// This is a comment
Purpose of Using System in C#
In C#, namespaces are used to arrange a large number of classes so that the program can be easily managed. System is used in a basic C# program. Console is a class that belongs to the System namespace. We must use namespacename to get the class of a namespace.
Uses of Static void main(string args)
The Main method describes what the class does when it is run and creates additional objects and variables. Because it is accessible to run when the C# program starts, a main method is static. It is the program’s starting point, and it runs without even creating a class object.
Namespace in C#
The purpose of a namespace is to provide a means to keep one set of names from interfering with another. No conflict exists between class names declared in different namespaces.
