Question

I hope this is a simple question. I’m building a simple console application in C#. I have a class:

using System;
using Filter;

public class Params
{
    public string key;
    public bool distinct;
    public List<string> fields;
    public string filter;
    public int limit;
    public int skip;
    public bool total;
    public List<Tuple<string, GroupType>> group;
    public List<Tuple<string, OrderType>> order;

    public Params()
    {
        key = "";
        distinct = false;
        fields = new List<string>();
        filter = "";
        group = new List<Tuple<string, GroupType>>();
        limit = 0;
        order = new List<Tuple<string, OrderType>>();
        skip = 0;
        total = false;
    }

    public void AddGroup(string field, GroupType type)
    {
        group.Add(new Tuple<string, GroupType>(field, type));
    }

    public void AddOrder(string field, OrderType type)
    {
        order.Add(new Tuple<string, OrderType>(field, type));
    }
}

My program .cs class is:

namespace csharpExample
{
    class Program
    {
        public static void Main(string[] args)
        {
            Params p = new Params();
            Console.WriteLine("Test");
        }
    }
}

I want to use Params in my program.cs class where Main() is called. I thought I could simply use Params like above. I’ve also tried to do a using Params; both of these are errors in VS since it can’t find the directive. I’ve also tried adding my own namespace: namespace MyNameSpace; around my Params class. When I do this I still am unable to do a using MyNameSpace; statement as it can’t find it.

I just want to extract out a bunch of functions into a class that I can reuse. How do i call this class once it’s created?

-Thanks
Thanks for the help.

Are you talking about calling the constructor or the properties you are setting? You can set the class at the top of your base class and then call the instance of it. But since it is a static class you should probably use a helper method in the main.

namespace Example
{
    public class Program
    {
        Params p = new Params();

        string writefromParams()  // I exist just to give the string back from params with a nonstatic method
        {
            return p.key;
        }

        static void Main(string[] args)
        {
            Program p2 = new Program();  // set up a new instance of this very class

            Console.WriteLine(p2.writefromParams());  // get non static method from class


            Console.ReadLine();
        }
    }
}
