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

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

声明一个对象

protected CXXX _myObject;

然后，在Page_Load：

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

然后，在default.aspx中，你可以这样做：

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

Answer 2

写代码背后的代码

  SqlDataSource1.ConnectionString=Class1.StringConnectionObj;
