        dataGridView1.Rows.GetRowCount(DataGridViewElementStates.Selected);
    if (selectedRowCount > 0)
    {
        System.Text.StringBuilder sb = new System.Text.StringBuilder();

        for (int i = 0; i < selectedRowCount; i++)
        {
            sb.Append("Row: ");
            sb.Append(dataGridView1.SelectedRows[i].Index.ToString());
            sb.Append(Environment.NewLine);
        }

        sb.Append("Total: " + selectedRowCount.ToString());
        MessageBox.Show(sb.ToString(), "Selected Rows");
    }
}

Private Sub selectedRowsButton_Click( _
    ByVal sender As Object, ByVal e As System.EventArgs) _
    Handles selectedRowsButton.Click

    Dim selectedRowCount As Integer = _
        dataGridView1.Rows.GetRowCount(DataGridViewElementStates.Selected)

    If selectedRowCount > 0 Then

        Dim sb As New System.Text.StringBuilder()

        Dim i As Integer
        For i = 0 To selectedRowCount - 1

            sb.Append("Row: ")
            sb.Append(dataGridView1.SelectedRows(i).Index.ToString())
            sb.Append(Environment.NewLine)

        Next i

        sb.Append("Total: " + selectedRowCount.ToString())
        MessageBox.Show(sb.ToString(), "Selected Rows")
