Question

I have a class RequestDetail. There are 2 classes classA and classB derived from it such that each of them has their own property:

public partial classA : RequestDetail { ..... }
public partial classB : RequestDetail { ..... }

I am writing a method CreateMethod1(ClassA a) and CreateMethod2(ClassB b).

Both methods doing the same stuff except some minor difference. I would like to write a generic method and call that method by passing the reference in CreateMethod1 and CreateMethod2.

Can anyone help me in doing this?

THanks

EDIT:

What I have excluded is I have received a WSDL which when generated gives me four separate classes that inherit from a base class with around 20 properties. They only differ very slightly, to be exact 2 classes contain the same field (IsUrgent), the third contains (Ticket and Reason) and the fourth contains (BudgetCode) The persistance however is exactly the same for all implementations. I dont want to create 4 seperate methods to persist the same information.

Its worth noting the classes are partial.

xsd looks like following

<xs:complexType name="ClassA">
    <xs:complexContent>
      <xs:extension base="IARequestDetails">
        <xs:sequence>
          <xs:element name="IsUrgent" type="IAUrgency"/>
        </xs:sequence>
      </xs:extension>
    </xs:complexContent>
  </xs:complexType>

  <xs:complexType name="ClassB">
    <xs:complexContent>
      <xs:extension base="IARequestDetails">
        <xs:sequence>
          <xs:element name="BudgetCode" type="ProjectBudgetCode"/>
          <xs:element name="IsUrgent" type="IAUrgency"/>
        </xs:sequence>
      </xs:extension>
    </xs:complexContent>
  </xs:complexType>

Here is a solution using partial classes an interface and generic constraints … you will need to build the list of parameters that need to be returned in the Params implemenation for each of your sub classes, super class properties are naturally available.

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

namespace ConsoleApplication3
{
    public interface IABInterface
    {
        //Could be your SqlParameters
        string[] Params { get; }
    }

    public partial class IARequestDetails
    {
        public int One
        {
            get; set; 
        }

        public int Two
        {
            get;set;
        }
    }

    public partial class ClassA : IARequestDetails
    {
        public int IsUrgent 
        {
            get;set;
        }
    }

    public partial class ClassB : IARequestDetails
    {
        public int BudgetCode
        {
            get;
            set;
        }

        public int IsUrgent
        {
            get;
            set;
        }
    }

    public partial class ClassA : IABInterface
    {
        #region IABInterface Members

        public string[] Params
        {
            //Create your list of parameters
            get { return null; }
        }

        #endregion
    }

    public partial class ClassB : IABInterface
    {
        #region IABInterface Members

        public string[] Params
        {
            get
            {
                return null;
            }
        }
        #endregion
    }

    public class Persist
    {
        public void Save<T>(T obj)
            where T : IARequestDetails, IABInterface
        {
            //Do you saving here ... 
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            Persist persist = new Persist();

            persist.Save(new ClassA());
            persist.Save(new ClassB());
        }
    }
}
