What is the purpose of namespaces in C#?

What is the purpose of namespaces in C#?

Namespaces in C# are used to organize code and prevent naming conflicts by grouping related classes, interfaces, and other types.

Can you give me an example of how to define a namespace?

Sure! You can define a namespace like this:

namespace MyApplication.Utilities {
    public class Helper {
        // Class implementation
    }
}

How do I use a class from a different namespace?

To use a class from a different namespace, you need to include a using directive at the top of your file, like this:

using MyApplication.Utilities;

class Program {
    static void Main() {
        Helper helper = new Helper();
    }
}

What happens if two classes in different namespaces have the same name?

If two classes in different namespaces have the same name, you can still use both by specifying the full namespace when referencing the class, like Namespace1.ClassName and Namespace2.ClassName.
