Howto add rows to a featuredatatable

Hi All,

I want to append featura data rows to an existing feature data table by use of:

_FDTIntersection.Rows.Add (ds.Tables[0].DefaultView.Table.Rows);

Always I get a "System.NotSupportedException". The _FDTIntersection is an object (not null), ds is a dataset type of SharpMap.Data.FeatureDataSet with one table and some rows.

While looping through any functions I like to add the results to the feature data table. So, what is the right way to adding rows?

Please give me some suggestions. Thanks in advance.

I'm using v0.9

Hi puNk,
something like :

public static void ImportRows(FeatureDataTable source, FeatureDataTable target)
            foreach(FeatureDataRow r in source.Rows)
                FeatureDataRow newRow = source.NewRow();
                newRow.Geometry = r.Geometry.Clone();
                newRow.ItemArray = r.ItemArray;

will work as long as source and target have the same schema. You can then use it like:
ImportRows(ds.Tables[0], _FDTIntersection);
