How to access web.config settings directly in .asp

问题:

I've created a web page and it contains some settings value in Web.Config for example images. So I want to give the path of images in Web.Config file and file name in that particular image src.

I wanted to read that settings only in aspx page not in codebehind.

For example

Below is my code:

Web.Config:
<add key="ImagePath" value="http://192.168.0.181/Labeling/Images/"/>

and in my aspx page,

<img id="ImgHeader" runat="server" src="<%ConfigurationManager.AppSettings["ImagePath"]%>" />

回答1:

<img id="ImgHeader" runat="server" src="<%$ ConfigurationSettings.AppSettings["ImagePath"] %>" />

Should do the trick.

Waqas Iqbal's answer:

<%$ AppSettings:ImagePath %> 

from Binding ASP.Net Web.Config Settings To .ASPX File <a href></a>? worked nicely!

回答3:

<%= ConfigurationSettings.AppSettings["ImagePath"] %>

This worked for me:

<%= ConfigurationManager.AppSettings("ImagePath") %>
