Asserts that the calling code can access the resource identified by the current permission object, even if callers higher in the stack have not been granted permission to access the resource.
Assembly: mscorlib (in mscorlib.dll)
Calling stops the permission check on callers higher in the call stack. Therefore, even if these callers do not have the requisite permissions, they can still access resources. An assertion is effective only if the code that calls passes the security check for the permission that it is asserting.
is ignored for a permission not granted because a demand for that permission will not succeed. However, if code lower on the call stack calls Demand for that permission, a SecurityException is thrown when the stack walk reaches the code that tried to call . This happens because the code that called has not been granted the permission, even though it tried to it.
Because calling removes the requirement that all code in the call chain must be granted permission to access the specified resource, it can open up security vulnerabilities if used incorrectly or inappropriately. Therefore, it should be used with great caution.
