Forces a SecurityException at run time if all callers higher in the call stack have not been granted the permissions specified by the current instance.
Assembly: mscorlib (in mscorlib.dll)
A caller in the call chain does not have the permission demanded.
Use on a PermissionSet to ensure that all callers have all permissions in the set with one operation.
The permissions of the code that calls this method are not examined; the check begins from the immediate caller of that code and proceeds up the stack. The call stack is typically represented as growing down, so that methods higher in the call stack call methods lower in the call stack. succeeds only if no SecurityException is thrown.
The following code example shows the use of the method to demand all the permissions in a permission set. This code example is part of a larger example provided for the PermissionSet class.
