ContractHelper.RaiseContractFailedEvent Method

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

Used by the binary rewriter to activate the default failure behavior.

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

Syntax

'Declaration
<DebuggerNonUserCodeAttribute> _
Public Shared Function RaiseContractFailedEvent ( _
    failureKind As ContractFailureKind, _
    userMessage As String, _
    conditionText As String, _
    innerException As Exception _
) As String

[DebuggerNonUserCodeAttribute]
public static string RaiseContractFailedEvent(
    ContractFailureKind failureKind,
    string userMessage,
    string conditionText,
    Exception innerException
)

Parameters

  • conditionText
    Type: System.String
    The description of the condition that caused the failure.
  • innerException
    Type: System.Exception
    The inner exception that caused the current exception.

Return Value

Type: System.String
A null reference (Nothing in Visual Basic) if the event was handled and should not trigger a failure; otherwise, returns the localized failure message.

Exceptions

Exception Condition
ArgumentException

failureKind is not a valid ContractFailureKind value.

Remarks

The binary rewriter calls this method to notify listeners about a contract failure. The RaiseContractFailedEvent method does not perform the failure behavior (an assert or throw) itself. If the failure is handled by the listeners, the method returns nulla null reference (Nothing in Visual Basic). If the failure is not handled by the listeners, a localized failure message is returned.
