Question

I am trying to load the values from a List<dataset> to List<Person>

I’ve written the following code, but am unsure what to do next

public List<Person> AddressFinderBLL_GetAddressbyName(String pfname,)
{ 
    List<Person> Per= new List<Person>();
    List<DataSet> lstPer = new List<DataSet>(); 
    lstPer = Adal.AddressFinderDAL_GenerateDatabyName(
      pfname, pfnameval, plname, plnameval);
      //here List<Dataset> lstPer loaded with values from back end foreach(DataRow item in lstPer[0].Tables[0].Rows)
{
    // here i need to assign the values to List<Person> from List<Dataset>[0].tables[0].rows; 
}                           

Person class has following attributes class class Person
{

    public String _firstname,_middlename;

    public Person()
    {
    }
    public String Firstname
    {
        get
        {
            return _firstname;
        }
        set
        {
            _firstname = value;
        }

    }

    public String Middlename
    {
        get 
        {
            return _middlename;
        }
        set
        {
            _middlename = value;
        }
    }

} please let me know

I don’t know what column names your DataSet has, but here’s an approximation:

List<Person> pers = lstPer[0].Tables[0].AsEnumerable().
                    Select(r=> new Person() { 
                        FirstName = r.Field<string>("fieldname1"),
                        MiddleName = r.Field<string>("fieldname2")
                    })
                    .ToList();

Incidentally, a method returning a list of DataSets seems kind of unlikely. Are you sure that part’s right? Perhaps it returns one DataSet that contains multiple tables?
