Checks for a condition; if the condition is false, follows the escalation policy set by the analyzer and displays the specified message.
Assembly: mscorlib (in mscorlib.dll)
[ConditionalAttribute("CONTRACTS_FULL")] [ConditionalAttribute("DEBUG")] public static void Assert( bool condition, string userMessage )
Parameters
- condition
- Type: System.Boolean
The conditional expression to test.
- userMessage
- Type: System.String
A message to display if the condition is not met.
The default escalation policy is to notify the attached debugger about a contract failure or to display an Assert dialog box if a debugger is not attached. Optionally, the analyzer can be instructed to throw an exception. The userMessage parameter is passed to the debugger output. If userMessage is not a constant string literal, tools may not be able to read it.
