Read the error message:

Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

The do exactly what it says: your web page app is trying to perform an IO operation that needs it to have specific permissions. Only your admin can change the permissions your app runs under, or the permissions on the folder or file it is trying to access.

Solution 2

As stated by OriginalGriff, its a access permission issue, add below tag in web.config

XML

<system.web>
<trust level="Full"/>
</system.web>

Hope it helps

After Adding <trust level="Full"/> in web.config I got this error

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: This configuration section cannot be used at this path. This happens when the site administrator has locked access to this section using <location allowoverride="false"> from an inherited configuration file.

Source Error:

An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
