Namespaces in C#

In this article, we will find out about Namespaces in C#. What is Namespace, how to utilize Namespace in the program? Learn with Examples.

C# Namespace

In C# namespaces are utilized to bunch comparable kind of classes. Two classes with the same name in various namespaces never struggle to one another.

In C# namespace can be:

• Client characterized
• Pre characterized, that is an in-inherent .NET class library

Here, we have to utilize utilizing watchword to get to characterized namespaces.

Syntax:

namespace <namespace_name>
{
	//Write code here
}

Note:

• To announce client characterized namespace we have to utilize namespace catchphrase.
• In the event that we need to get to a class characterized inside a namespace, at that point we need use. (spot) Operator.

Example:

using System;
using System.Collections;

namespace namespace1
{
    class ABC
    {
        public void fun()
        {
            Console.WriteLine("Inside Namespace1");
        }
    }
}

namespace namespace2
{
    class ABC
    {
        public void fun()
        {
            Console.WriteLine("Inside Namespace2");
        }
    }
}    
    
class Program
{
    static void Main()
    {
        namespace1.ABC OB1 = new namespace1.ABC();
        namespace2.ABC OB2 = new namespace2.ABC();

        OB1.fun();
        OB2.fun();

    }
}

Output

    Inside Namespace1
    Inside Namespace2
