To write the code in Visual Basic.NET

Private connString As String
<WebMethod(Description:="Returns a DataSet containing all Products")> _
Public Function GetProduct() As Data.DataSet
  connString = "Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=C:\Users\[User Name]\Documents\ComponentOne Samples\ActiveReports 9\Data\nwind.mdb"
  Dim adapter As New Data.OleDb.OleDbDataAdapter("select * from products", connString)
  Dim ds As New Data.DataSet()
  adapter.Fill(ds, "Products")
  Return ds
End Function

To write the code in C#

private static string connString = "Provider=Microsoft.Jet.OLEDB.4.0;
Data Source = C:\\Users\\[User Name]\\Documents\\ComponentOne Samples\\ActiveReports 9\\Data\\nwind.mdb";
[WebMethod(Description="Returns a DataSet containing all Products")]
public Data.DataSet GetProduct()
{
   Data.OleDb.OleDbDataAdapter adapter;
   Data.DataSet ds;
   adapter = new Data.OleDb.OleDbDataAdapter("select * from products", connString);
   ds = new Data.DataSet();
   adapter.Fill(ds, "Products");
   return ds;
}
