Suppose we have the followings on our web.config file:
- <appSettings>
- <add key="serverip" value="###.##.#.##"/>
- </appSettings>
- <connectionStrings>
- <add name="conn" connectionString="Server=###.##.#.##;User=root;Password=12345;Database=test;"/>
- </connectionStrings>
Then using the following set of steps we can read our config file.
Step 1:- Add the following piece of code in the head section of .aspx
page.
- <script type="text/javascript">
- function ReadConfigFile()
- {
- var conStr = '<%=ConfigurationManager.ConnectionStrings["conn"].ConnectionString %>'
- alert(conStr);
- var appStr = '<%=ConfigurationManager.AppSettings["serverip"].ToString() %>'
- alert(appStr);
- }
- </script>
Step-2: Now take a button and call the above function on its OnClientClick
event.
- <asp:Button ID="Button1" runat="server" Text="display webconfig" OnClientClick="ReadConfigFile()" />
