在sqldatasource中调用连接字符串

Question

我们如何从类中调用Sqldatasource中的连接字符串而不是直接写入？

<asp:SqlDataSource ID="sqldatasource" runat="server" ConnectionString="..." SelectCommand="sp" SelectCommandType="StoredProcedure">  

    </asp:SqlDataSource> 

Answer 1

在后面的代码写

SqlDataSource1.ConnectionString=Class1.StringConnectionObj;

Answer 2

public class CXXX { 
    public String ConnectionString() { 
      return "data source=.\SQLEXPRESS;Initial Catalog=DB;Integrated Security=True;MultipleActiveResultSets=True;Pooling=false;"; 
     } 
} 

声明对象

protected CXXX _myObject; 

然后，在Page_Load中：

protected void Page_Load(object sender, EventArgs e) 
{ 
     _myObject = new CXXX(); 
} 

然后，在Default.aspx的，你可以这样做：

<asp:SqlDataSource ID="sqldatasource" runat="server" ConnectionString="<%= CXXX .ConnectionString() %>" SelectCommand="sp" SelectCommandType="StoredProcedure"> 
</asp:SqlDataSource>
