C#

Hi,

I am creating a console application wherin i created two class files Edi837GeneratorBase.cs and BlueGrassReportingGenerator.cs

In Edi837GeneratorBase.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SCS.SNDS.PH.EdiExport.DataAccess.LinqToSql;
using System.IO;
using SCS.SNDS.PH.EdiExport.X12Edi837Ver5010;
using SCS.SNDS.PH.EdiExport;
using System.Data.Common;
namespace SCS.SNDS.PH.Edi837GeneratorConsole
{
    public class Edi837GeneratorBase : IEdiGenerator
    {
        public Edi837GeneratorBase(string groupID,DateTime startDate,DateTime endDate)
        {
            context = new X12837DataContext();
            context.CommandTimeout = 240;
            context.Connection.Open();
            transaction = context.Connection.BeginTransaction();
            context.Transaction = transaction;
            Container.SetupContainer(context);
            submissionGroupID = groupID;
            startDate = this.startDate;
            endDate = this.endDate;
            outWorker = GetOutworker();
        }
       
    }

}

Now, i have class BlueGrassReportingGenerator.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SCS.SNDS.PH.EdiExport.DataAccess.LinqToSql;
using System.Data.Common;
using System.Data;
using System.IO;
using SCS.SNDS.PH.EdiExport.X12Edi837Ver5010;
using SCS.SNDS.PH.EdiExport;
namespace SCS.SNDS.PH.Edi837GeneratorConsole
{
    public class BlueGrassReportingGenerator : Edi837GeneratorBase
    {
        public BlueGrassReportingGenerator() : base(Properties.Settings.Default.BlueGrassReportingSubGroupID, startDate, endDate)
        {
        }
    }
}

i am trying to access the Edi837GeneratorBase in Edi837GeneratorBase.cs Class from BluegrassReportingGenerator.cs class but i am getting an error and thestart Date and Date time are underlined with red line

Error 84 An object reference is required for the non-static field, method, or property


Could anyone please help me to how to access this.

Thanks in advance
