Contract.EnsuresOnThrow<TException> Method (Boolean)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Specifies a postcondition contract for the enclosing method or property, based on the provided exception and condition.

Namespace: System.Diagnostics.Contracts
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
<ConditionalAttribute("CONTRACTS_FULL")> _
Public Shared Sub EnsuresOnThrow(Of TException As Exception) ( _
    condition As Boolean _
)

[ConditionalAttribute("CONTRACTS_FULL")]
public static void EnsuresOnThrow<TException>(
    bool condition
)
where TException : Exception

Type Parameters

TException
The type of exception that invokes the postcondition check.

Parameters

condition
Type: System.Boolean
The conditional expression to test.

Remarks

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.
