访问数据库连接字符串(sql连接)

ConnectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True" SelectCommand="SELECT top 5 title FROM [Movies]"

<asp:SqlDataSource ID="srcMovies" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT top 5 title FROM [Movies]" runat="server"></asp:SqlDataSource>

web.config：

<connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True"
        providerName="System.Data.SqlClient" />
