我在asp.net网站上使用Microsoft Visual Web Developer 2010 express。我有以下代码;
在文件Web配置
中<configuration>
<connectionStrings>
<add name="ConnectionString" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=ReplaceToken\abcDATA.accdb;Persist Security Info=True;Jet OLEDB:Database Password=abc"
providerName="System.Data.OleDb" />
</connectionStrings>
<system.web>
<compilation debug="false" strict="false" explicit="true" targetFramework="4.0" />
</system.web>
</configuration>
在文件Default.aspx
中<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"
DataSourceID="SqlDataSource1" DataTextField="PickList"
DataValueField="PickList">
</asp:DropDownList>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>"
SelectCommand="SELECT [PickList] FROM [T_BAS_PASexport]">
</asp:SqlDataSource>
在ConnectionString行的Web Config文件中,我想在应用程序/网站运行时将单词ReplaceToken替换为当前目录路径。请有人帮助我,我该怎么做。我需要在Default.aspx.vb文件中放入什么代码,之后我需要在Default.aspx文件中进行更改。非常感谢一个简短的解释。

试试这个:
//In file Default.aspx.cs
public static string CustomConnectionString
{
get
{
var connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
connectionString.Replace("ReplaceToken", "TODO");
return connectionString;
}
}
//In file Default.aspx
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%= CustomConnectionString %>"
