How To Create Namespaces and Classes In C# | C# Directories | C# Tutorial For Beginners |

C# Namespaces

Namespaces in C# are used to organize too many classes so that it can be easy to handle the application.

In a simple C# program, we use System.Console where System is the namespace and Console is the class. To access the class of a namespace, we need to use namespacename.classname. We can use using keyword so that we don't have to use complete name all the time.

In C#, global namespace is the root namespace. The global::System will always refer to the namespace "System" of .Net Framework.

Classes and Objects

You learned from the previous chapter that C# is an object-oriented programming language.

Everything in C# is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake.

A Class is like an object constructor, or a "blueprint" for creating objects.


C# Namespace and Class


Sure, I can explain how to create namespaces and classes in C#

To create a namespace in C#, you use the namespace keyword followed by the name of the namespace. Here's an example:

arduino
Copy code
namespace MyNamespace
{
// code goes here
}
All code inside the curly braces will be part of the MyNamespace namespace. Namespaces are used to group related code together and prevent naming conflicts with other code.

To create a class in C#, you use the class keyword followed by the name of the class. Here's an example:

arduino
Copy code
namespace MyNamespace
{
public class MyClass
{
// code goes here
}
}
All code inside the curly braces will be part of the MyClass class. Classes are used to define objects with properties, methods, and events.

You can also create nested classes within other classes. Here's an example:

kotlin
Copy code
namespace MyNamespace
{
public class MyClass
{
public class MyNestedClass
{
// code goes here
}
}
}
The MyNestedClass class is nested inside the MyClass class.

Finally, it's worth noting that you can use access modifiers to control the visibility of namespaces and classes. For example, you can use the public keyword to make a namespace or class visible to other parts of your code.
