C# error while calling class

I learned basic and now I want to learn OOP in C# I have this code 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace uceni_cs
{
    class Zdravic
    {
        public void pozdrav()
        {
            Console.WriteLine("Ahoj světe ! ");
        }
    }

}

But when I try to call it using this code

namespace uceni_cs
{
    class Zdravic
    {
        public void pozdrav()
        {
            Console.WriteLine("Ahoj světe ! ");
        }
    }
    Zdravic trida = new Zdravic();
}

In code Zdravic trida = new Zdravic(); is error. A namespace cannot directly contain members such as fields or methods. What I am doing wrong ? I just want to call the class. Thanks

In C# there is no such a thing global variable so you can't just create new instance of Zdravic type that does not belong to any class.

I suggest you to read General Structure of a C# Program, and c# Classes and Structs.

Create your class object in main method and then use the class properties using that object.

 Zdravic trida = new Zdravic();

in main method of you program/application.

You need to create an entry point to your application and instantiate the class there.

class EntryPoint
{
    static void Main()
    {
        Zdravic trida = new Zdravic();

        trida.pozdrav();
    }
}
