3 (Day02)

This is the namespace of our existing console application.

A namespace is a way to keep one set of names separate from another, which means you can create as many namespaces as you want and the classes under different namespaces will treat them as a separate, although they have the same name; that is, if you declare a ClassExample class in namespace Day02, it would be different from the ClassExample class declared in the Day02New namespace and will work without any conflicts.

This is a typical example that shows two classes of the same name with two different namespaces:

namespace Day02 
{ 
public class ClassExample 
    { 
public void Display() 
        { 
Console.WriteLine("This is a class 'ClassExample' of namespace 'Day02'. "); 
        } 
    } 
} 
 
namespace Day02New 
{ 
 
public class ClassExample 
    { 
public void Display() 
        { 
Console.WriteLine("This is a class 'ClassExample' of namespace 'Day02New'. "); 
        } 
    } 
} 

The preceding code would be called like this:

private static void SameClassDifferentNamespacesExample() 
{ 
var class1 = new ClassExample(); 
var class2 = new Day02New.ClassExample(); 
    class1.Display(); 
    class2.Display(); 
} 

This will return the following output:
