DateTime in .NET

To get the time and date from system why do I need System.DateTime.Now ? As you can see there is a System namespace already declared at the top. If I just write DateTime.Now it doesn't work. I learned earlier that If we declare "using System" then we don't have to declare or write System.Console.WriteLine or System.DateTime.Now etc.

using System;
using System.Text;

namespace DateTime
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("The current date and time is " + System.DateTime.Now);
        }
    }
}

Because your Program class is in a namespace called DateTime. That conflict means the compiler will look for a type called Now in your namespace DateTime which obviously doesn't exist.

Rename your namespace and you won't have the problem.

It's because your namespace is already called DateTime which clashes with an existing class name. So you could either:

namespace DateTime
{
    using System;
    using System.Text;

    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("The current date and time is " + DateTime.Now);
        }
    }
}

or find a better naming convention for you own namespaces which is what I would recommend you doing:

using System;
using System.Text;

namespace MySuperApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("The current date and time is " + DateTime.Now);
        }
    }
}
