The ErrorHandler type exposes the following members.

	Name	Description
	CallWithCOMConvention(Action, Boolean)	Use this method when an interop interface might be implemented by managed code, and it is expected to return HRESULT error codes but also throws exceptions. This method catches all except the critical exceptions and returns the corresponding HRESULT for the caught exception.
	CallWithCOMConvention(Func<Int32>, Boolean)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Failed	Determines whether an HRESULT is an error return code.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsCriticalException	Determines whether the specified exception is critical.
	IsRejectedRpcCall	Determines whether the parameter is a failure HRESULT that indicates a failed RPC call that may succeed if retried at a later time.
	Succeeded	Determines whether an HRESULT is a success return code.
	ThrowOnFailure(Int32)	Determines whether the parameter is a success or failure HRESULT and throws an exception in case of failure.
	ThrowOnFailure(Int32, array<Int32[])	Determines whether the parameter is a success or failure HRESULT and throws an exception if it is a failure that is not included in the array of well-known failures.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
