'Declaration <ConditionalAttribute("CONTRACTS_FULL")> _ Public Shared Sub EnsuresOnThrow(Of TException As Exception) ( _ condition As Boolean _ )
The type of exception that invokes the postcondition check.
- Type: System.Boolean
The conditional expression to test.
The condition parameter specifies a postcondition that is expected to be true when the enclosing method or property terminates abnormally and an exception of type TException is thrown.
This method call must be at the beginning of a method or property, before any other code.
This contract is exposed to clients; therefore, it must only reference members that are at least as visible as the enclosing method.
You must use the binary rewriter for run-time enforcement of this postcondition.
