For programmers it is more important that you identify whether you are allowed to do something.

Introduction

One of the most important tasks is to getting and setting the security access for all the administrator. For programmers it is more important that you identify whether you are allowed to do something.
 
Let’s start to learn how we can get the security access information. The System.Security.Permissions namespace contain a number of different kinds of permissions. For this purpose we use the following
 
Class:
(i) System.Security.Permissions.RegistryPermission.
(ii) System.Security.Permissions.UIPermission.
Enum:
(i) System.Security.Permissions.FileIOPermissionAccess.
 
For more information about System.Security.Permissions can be found at this link.[^]
 
A sample code is given below:

Code

public class SecurityAccessExample
{
    public void GetSecurityAccess()
    {
        System.Security.Permissions.RegistryPermission _objRegistryPermission
                = new RegistryPermission(RegistryPermissionAccess.Read, "HARDWARE\\DESCRIPTION\\SYSTEM\\0");
        try
        {
            // verify for permission to read the registry key
            if (_objRegistryPermission.IsUnrestricted())
            {
                Console.WriteLine("Unrestricted Access ALLOWED.");
            }
            else
            {
                Console.WriteLine("Unrestricted Access DENIED.");
            }
            // Verify clipboard access
            System.Security.Permissions.UIPermission _objUIPermission
                = new UIPermission(UIPermissionWindow.AllWindows, UIPermissionClipboard.AllClipboard);
            if (_objUIPermission.IsUnrestricted())
            {
                Console.WriteLine("UI Unrestricted Access ALLOWED.");
            }
            else
            {
                Console.WriteLine("UI Unrestricted Access DENIED.");
            }
            // Verify local files access
            Console.WriteLine("Local files read access: {0}"
                           , System.Security.Permissions.FileIOPermissionAccess.Read);
            Console.WriteLine("Local files write access: {0}"
                           , System.Security.Permissions.FileIOPermissionAccess.Write);
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }
}
