Read web.config keys in MVC

To Retrieve Configuration Values from Web.Config in MVC, you should follow the below steps in detail:

1- Open your MVC application and find Web.Config in the root directory of your project.

2- Add a new Key with its value in appSettings section

<configuration>
    <appSettings>
        <add key="NewSetting" value="NewValue" />
    </appSettings>
</configuration>

• NewSetting : That's the key that is used in the code to retrieve its corresponding value for example : replace NewSetting with RootURL
• NewValue : That's the value for example : replace NewValue with https://www.google.com/

3- In the controller, you need to write the following code to retrieve data using the RootURL from the configuration.

string RootURL= System.Configuration.ConfigurationManager.AppSettings["RootURL"];
