Classes that Implement IPermission

Class Description
CodeAccessPermission Defines the underlying structure of all code access permissions.
PrincipalPermission Allows checks against the active principal (see IPrincipal) using the language constructs defined for both declarative and imperative security actions. This class cannot be inherited.

Remarks

Permissions in the common language runtime are objects that describe sets of operations that can be secured for specified resources. A permission object describes operations or access that is subject to security control; it does not represent access or a right to perform operations. Permissions are used by both application code and the .NET Framework security system in the following ways.

  • Code requests the permissions it needs in order to run.
  • The security system policy grants permissions to code in order for it to run.
  • Code demands that calling code has a permission.
  • Code overrides the security stack using assert/deny/permit-only.
Note   If you write a new permission, you must implement this interface in your class.
