CodeAccessPermission::Deny Method ()
Prevents callers higher in the call stack from using the code that calls this method to access the resource specified by the current instance.
Assembly: mscorlib (in mscorlib.dll)
The A issues a for a permission and then calls method B, method B can overtly override the by issuing an Assert. The called method is always higher in the stack. Therefore, if method B tries to access a protected resource, the security system begins checking for permissions with it because method B is the immediate caller, and then walks down the stack to confirm that there is no or PermitOnly lower in the stack. Method B, which is trying to access the resource, can stop the stack walk immediately by using the Assert method. In that case, the placed on the stack by method A (the calling method) is never discovered.method should be used only to protect resources from accidental access by fully trusted code. It should not be used to protect resources from intentional misuse by untrusted code. For example, if method
This method prevents callers higher in the call stack from accessing the protected resource through the code that calls this method, even if those callers have been granted permission to access it. The call stack is typically represented as growing down, so that methods higher in the call stack call methods lower in the call stack.
Demand for that permission is invoked by a caller lower in the call stack, that security check will fail when it reaches the .can limit the liability of the programmer or help prevent accidental security issues because it helps prevent the method that calls from being used to access the resource protected by the denied permission. If a method calls on a permission, and if a
