Using .net 2.0 to insert a single row of data

I need to add a row of data to a table. In my attempt below I receive an error message saying that I need a valid insertcommand. However, even if this would work, it looks a bit inefficient. Also, what I want to do is to add ONE row of data as efficient as possible and avoid the use of sql. (i.e. insert into test (test1,test2) values ("text1","text2")...)



        Dim sqlConn As New System.Data.SqlClient.SqlConnection(myConnection)
        Dim da As New SqlClient.SqlDataAdapter("Select * from Test", sqlConn)
        Dim ds As New DataSet

        sqlConn.Open()
        da.AcceptChangesDuringFill = True
        da.Fill(ds, "Test")

        Dim r As DataRow = ds.Tables("Test").NewRow()
        r("Test1") = "text1"
        r("Test2") = "text2"

        ds.Tables("Test").Rows.Add(r)

        da.Update(ds, "Test")

        sqlConn.Close()
