Escaping SelectParameters in ASP.NET

I have the following SQLDataSource:

<asp:SqlDataSource ID="topicSource" runat="server" ConnectionString="<%$ ConnectionStrings" 
        SelectCommandType="Text" SelectCommand="SELECT * FROM tbl_Topic WHERE TopicId = @TopicId">
        <SelectParameters>
    开发者_运维技巧        <asp:QueryStringParameter Name="TopicId" QueryStringField="id" />
        </SelectParameters>
    </asp:SqlDataSource>

Does ASP.NET escape the select parameter for me? If not, what do I do to make it safer to prevent injections?

Yes: in this case, you are fully protected from SQL injection. That's the whole point for having SQL parameters in this fashion.
