ActivityValidationServices.Validate Method

Definition

Namespace:

System.Activities.Validation

Assembly:

System.Activities.dll

Verifies that a workflow activity is correctly configured according to the validation logic. This logic can be the CacheMetadata(CodeActivityMetadata) method of the activities to validate, or build and policy constraints.

Overloads

Validate(Activity)	Verifies that a workflow activity is correctly configured according to the validation logic. This logic can be the CacheMetadata(CodeActivityMetadata) method of the activities to validate, or build and policy constraints.
Validate(Activity, ValidationSettings)	Verifies that a workflow activity is correctly configured according to the validation logic. This logic can be the cacheMetadata method of the activities to validate, or build and policy constraints.

Remarks

Custom activity authors can provide validation logic in an activity's CacheMetadata override. Any exceptions that are thrown from CacheMetadata are not treated as validation errors. These exceptions will escape from the call to Validate and must be handled by the caller.

Public Shared Function Validate (toValidate As Activity, settings As ValidationSettings) As ValidationResults

Parameters

toValidate

Activity

An activity from a workflow activity tree.

settings

ValidationSettings

An object that determines the behavior of the validation method on the workflow , can suppress the internal validation logic, and can also contain the policy constraints.

Returns

ValidationResults

A collection of validation errors, each of which can contain the name of the activity that is configured incorrectly, a descriptive message, an error or warning code , and other information.

Custom activity authors can provide validation logic in an activity's CacheMetadata override. Any exceptions that are thrown from CacheMetadata are not treated as validation errors. These exceptions will escape from the call to Validate and must be handled by the caller.
