DataSet ds =newDataSet();
using (OleDbConnection connection =newOleDbConnection(connectionString))
using (OleDbCommand command =newOleDbCommand(query, connection))
using (OleDbDataAdapter adapter =newOleDbDataAdapter(command))
{
adapter.Fill(ds,"tablename");
}
return ds;
然后直接用ds.tables["tablesname"]就可以了
