How to convert DataView,DataRowView to Generic Typed Lists

问题

Is there any possible method than looping, Enumerating the ICollection to convert them respectively to Typed List knowing the columns in the ICollection. I am using .net Framework 2.0, C#2.0. Expected answer would be something like this,a one liner

List<Bills> bills = GetBills(DataView/DataRowView/ICollection);

where Bills type would have BillNumber, BillDate, BilledTo as properties. The DataRowView/DataView would have corresponding Columns with records in them. Is there a factory build method that does the Job? If No any one liner to do it?

回答1:

Could you do it in one line using a LINQ Select with a lambda? Something along these lines....

List<Bills> bills = yourDataView.Rows.Select(t => new Bills() {BillNumber = t["BillNumber"], BillDate = t["BillDate"], BilledTo = t["BilledTo"]}).ToList();

Use Linq Select to convert the DataView rows to a List of objects:

DataView yourDataView;

List<Bills> bills = yourDataView.ToTable().Rows.Cast<DataRow>()
                    .Select(r => new Bills() 
                    { 
                        BillNumber = r.Field<int>("BillNumber"), 
                        BillDate = r.Field<DateTime>("BillDate"), 
                        BilledTo = r["BilledTo"].ToString()                 
                    }).ToList();
