I have a Typed DataSet DataTable which inherits TypedTableBase
, which in turn implements IEnumerable
. I can\'t seem to get this to wo
In order to do what you want, you must add the following reference to your project:
System.Data.DataSetExtensions
Once you have that added, you can order your DataTable like this:
var query = myDataTable.OrderBy(x => x.ID).ThenBy(y => y.ID2);
// use the DataView generated from the LINQ query
DataView dtv = query.AsDataView();
In order to iterate through the DataView, you can do the following:
var dtv = query.AsDataView();
foreach(DataRowView rw in dtv)
{
// you can also cast back to the typed data...
MyCustomRowType typedRow = (MyCustomRowType) rw.Row;
// do something here...
}
Alternatively you can typecast via LINQ this way:
var dtv = query.AsDataView().Cast();
// rowItem is of type MyCustomRowType...
foreach(var rowItem in dtv)
{
// do something here...
}
