Public Class Validator
This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.
The Validator class is used to ensure that activities are configured properly at design time. Validators are instantiated during design time when the designer validates the properties assigned to activities; if an activity's parameters are not configured properly, the designer will show smart tag errors for the incorrect values. Validators also run during compile time, and will return validation errors if constraints such as object parent or child type, minimum number of children, etc. are not correct. Validators will also run at runtime when a markup-based workflow is instantiated using the CreateWorkflow method.
The main purpose of a Validator is to ensure that errors are known during design time, and are not exposed as exceptions during runtime.
By default, validators will validate meta properties; they do not validate instance properties which are settable at runtime.
Initializes a new instance of the Validator class.
Determines whether the specified object is equal to the current object.(Inherited from Object)
Helper method to extract the full property name.
Serves as the default hash function.(Inherited from Object)
Gets the Type of the current instance.(Inherited from Object)
Creates a shallow copy of the current Object.(Inherited from Object)
Returns a string that represents the current object.(Inherited from Object)
Validates the specified object and returns a collection of validation errors.
When overridden in a derived class, validates a change based on a specified Activity being added or removed. This function is called during the application of changes that are made to the workflow during dynamic updates.
Helper method to automatically validate the specific objects properties.
|ValidateProperty(PropertyInfo, Object, Object, ValidationManager)||
Performs validation on a property and returns a ValidationErrorCollection that contains the results of that validation.
