Introduction:
Here I will explain how to use multiple web.config files in single application using asp.net
Description:
I attended one interview at that time they asked one question that is it possible to use multiple web.config files in single asp.net application? For that question answer is Yes we can use multiple web.config files in single web application but how? By creating web.config file in sub root folders we can use multiple web.config files in our application but each folder should contains only one web.config file. Here I will explain step by step how we can use multiple web.config files in our application.

I attended one interview at that time they asked one question that is it possible to use multiple web.config files in single asp.net application? For that question answer is Yes we can use multiple web.config files in single web application but how? By creating web.config file in sub root folders we can use multiple web.config files in our application but each folder should contains only one web.config file. Here I will explain step by step how we can use multiple web.config files in our application.
First create one new web application
that contains Default.aspx page and one web.config file. Now
right click on your application and select New folder after creation of
new folder right click on new folder select Add new item and add one
aspx page and one web.config file to this folder that files structure like this
After that write the following code in root
folder web.config file appsettings section like this
|
<appSettings>
<add key="rootfolder" value="Root Folder web.config"/>
<add key="test1" value="Testing the application for root folder web.config"/>
</appSettings >
|
After that open Default.aspx page
in root folder and write the following code
|
<html
xmlns="http://www.w3.org/1999/xhtml">
<head
runat="server">
<title>RootFolder
web.config</title>
</head>
<body>
<form
id="form1"
runat="server">
<div>
<b>
Root
Folder values
</b>
</div>
<br
/>
<div>
AppKey
value:
<b>
<asp:Label
ID="lbltxt"
runat="server"
Text="<%$appSettings:rootfolder %>"/>
</b>
<br
/>
Appkey
Test value:
<b>
<asp:Label
ID="Label1"
runat="server"
Text="<%$appSettings:test1 %>"/>
</b>
</div>
</form>
</body>
</html>
|
Now run your application and check the
output for root folder
Demo
After that open the sub root folder
web.config file and write the following code in appsettings section like
this
|
<appSettings>
<add key="subrootfolder" value="Sub Root Folder web.config"/>
<add key="test1" value="Testing the application for sub root folder web.config"/>
</appSettings >
|
After that open ChildPage.aspx
page in sub root folder and write the following code
|
<html
xmlns="http://www.w3.org/1999/xhtml">
<head
id="Head1"
runat="server">
<title>SubRoot
Folder web.config</title>
</head>
<body>
<form
id="form1"
runat="server">
<div>
<b>
SubRoot
Folder values
</b>
</div>
<br
/>
<div>
AppKey
value:
<b>
<asp:Label
ID="lbltxt"
runat="server"
Text="<%$appSettings:subrootfolder %>"/>
</b>
<br
/>
Appkey
Test value:
<b>
<asp:Label
ID="Label1"
runat="server"
Text="<%$appSettings:test1 %>"/>
</b>
</div>
</form>
</body>
</html>
|
Now run your application and check the
output for sub root folder
Demo
If
you observe above outputs Default.aspx page getting values from root
folder web.config file and ChildPage.aspx page getting values from subroot
folder web.config file.
In
this way we can use multiple web.config files in asp.net web application. I
hope it helps you
