I have to compare the IEnumerable data from UI and the IEnumerable data from SQL Server 2008 and have to insert/update the new elements from UI to DB and delete the elements from DB based on UI data.

I am having Distribution_X_ListType table in DB as:

    DistributionID ListTypeID EmployeeNumber DepartmentID LocationID
    1              2          84528          NULL         NULL 
    1              3          NULL           8051         NULL
    1              5          NULL           NULL         319
I am having an interface in a project as follows:

    public interface IDistributionList : IEntity
        {
            string Name { get; set; }
            bool ActiveFlag { get; set; }
            ...........................
            ...........................
            IEnumerable<IDistributionListType> ListTypes { get; set; }        
        }

The another interface is:

    public interface IDistributionListType
    {
        int? DistributionID { get; set; }
        int ListTypeID { get; set; }
        int EmployeeNumber { get; set; }
        int DepartmentID { get; set; }
        int LocationID { get; set; }
    }

In another project I am having Save function as follows:

    public int Save(IDistributionList distributionList)
            {
                SqlDataReader reader = null;            
                int rowsaffected = 0;
                try
                {
                    sqlcommand = new SqlCommand("spGetDistributionListTypeByID", con);  //spGetDistributionListTypeByID - This SP returns all the members from Distribution_X_ListType table for the given distribution ID
                    sqlcommand.CommandType = CommandType.StoredProcedure;
                    sqlcommand.Parameters.AddWithValue("@Distribution_ID", distributionList.ID);
                    
                    reader = sqlcommand.ExecuteReader();
    
                    while (reader.Read())
                    {
                          ????Value Should be stored in an IDistributionListType variable,say IDistributionListTypeFromDB 
                    }
                    ????IDistributionListType from function parameter(Lets say from UI) should be compared with the above IDistributionListTypeFromDB data.
                    ????Insert/Delete should be done in DB by comparing the data.
                 }
             }

Let the value of IDistributionListType from UI:

    DistributionID ListTypeID EmployeeNumber DepartmentID LocationID
    1              2          84528          NULL         NULL 
    1              5          NULL           NULL         64 


Let the value of IDistributionListType from DB:

    DistributionID ListTypeID EmployeeNumber DepartmentID LocationID
    1              2          84528          NULL         NULL 
    1              3          NULL           8051         NULL
    1              5          NULL           NULL         319

I need to update the DB with the data from UI. I am having two more SPs as :

    spInsertUpdateDistributionListType - Insert/Update Distribution_X_ListType table  based on DistributionID and listtypeID
    spDeleteDistributionListType - Delete Distribution_X_ListType table based on DistributionID and listtypeID

I don't know how to code in ???? areas. Anybody please helpout. Thanks in advance.
