How do I access Original and Modified versions of strongly typed DataRow?

I'm writing code to emulate a unit of work pattern in my winforms over datasets application.

I have the following:

foreach (EomApp1.Formss.Accounting.Data.AccountingView.AccountingViewRow 
                in accountingView.GetChanges(DataRowState.Modified).Tables[0].Rows)
            {
                 // break point -> immediate window

immediate window:

modified.Tables[0].Rows[0]["Cost/Unit", DataRowVersion.Original]
1
modified.Tables[0].Rows[0]["Cost/Unit", DataRowVersion.Current]
0

Is there any way to access the above information using strongly typed datasets? (in my example, accountingView is, but I don't know how to get at the changed DataRowVersion objects without using the string names of the columns.

Does the DataRowExtensions.Field extension method in System.Data.DataSetExtensions assembly solve this for you? Note parameters for DataColumn and DataRowVersion.

as far as I know there is none.
To get rid of the magic strings you could do

modified.Tables[0].Rows[0][Tables[0].CostUnitColumn.ColumnName, DataRowVersion.Current]
