ActivityValidator Class
Derivative of DependencyObjectValidator that is a base class for all activity validator components.
System.Workflow.ComponentModel.Compiler::Validator
System.Workflow.ComponentModel.Compiler::DependencyObjectValidator
System.Workflow.ComponentModel.Compiler::ActivityValidator
System.Workflow.Activities::CallExternalMethodActivityValidator
System.Workflow.Activities::HandleExternalEventActivityValidator
System.Workflow.ComponentModel.Compiler::CompositeActivityValidator
Assembly: System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)
The ActivityValidator type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetFullPropertyName | Helper method to extract the full property name. (Inherited from Validator.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() | Validate | Verifies that the given activity is valid. (Overrides DependencyObjectValidator::Validate(ValidationManager, Object).) |
![]() | ValidateActivityChange | 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. (Inherited from Validator.) |
![]() | ValidateProperties | Helper method to automatically validate the specific objects properties. (Inherited from Validator.) |
![]() | ValidateProperty | Performs validation on a property and returns a ValidationErrorCollection that contains the results of that validation. (Inherited from Validator.) |
The following example shows a complete ActivityValidator used for a custom activity. The custom activity is a ConsoleWriteLineActivity activity that has a single dependency property named Msg of type String. The validator ensures that the Msg property is set. If it is not set, the compiler displays an error when the Validate(ValidationManager, Object) method is called on the ActivityValidator and the compilation fails.
