The ContractInvariantMethodAttribute type exposes the following members.

Public methodContractInvariantMethodAttributeInitializes a new instance of the ContractInvariantMethodAttribute class.

Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The invariant method can have any name, but it must return void and take no parameters. A suggested name for the method is ObjectInvariant. The body of the invariant method must consist solely of one or more calls to the Contract.Invariant method. A type can have more than one contract invariant method, which can be public or private.
