Question

I am creating a WCF Service.
It receives data from a iPhone App.
When the user sends data from their iPhone I need to save the data
into our Database useing WCF Service.
In my WCF application I am creating a class and wrote the following code.

string connstr = ConfigurationManager.ConnectionStrings["myconn"].ToString();
string SQLstr = "myStoredProc1";

SqlConnection conn = new SqlConnection(connstr);
SqlCommand cmd = new SqlCommand(SQLstr, conn);

Intellisense is giving error for (constr, SQLstr)

A field initializer cannot reference the non-static field, method or
property.

Why I am getting this error. I see a lot of examples online with the same code.
Then why its giving error for my application. Is it because this class is in a WCF application.

This is how it sould look like:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;

namespace WCFRESTService100 
{ 
    public class myclass 
    { 
        string conn1 = ConfigurationManager.ConnectionStrings["myconn"].ToString(); 
        string SQLstr = "myStoredProc1"; 

        public void SomeMethod()
        {
            SqlConnection conn = new SqlConnection(SDconn);
            SqlCommand cmd = new SqlCommand(SQLstr, conn); 


        }
    } 
}
