TryCatch Class

Definition

Contains activities to be executed by the workflow runtime in an exception handling block.

public ref class TryCatch sealed : System::Activities::NativeActivity
public sealed class TryCatch : System.Activities.NativeActivity
type TryCatch = class
    inherit NativeActivity
Public NotInheritable Class TryCatch
Inherits NativeActivity
Inheritance

Examples

The following code sample demonstrates creating a TransactionScope activity. This example is from the Nesting of TransactionScope within a service sample.

Remarks

Note

The Finally activity member of a TryCatch activity that is the child of a TransactionScope will not execute if an unhandled exception propagates past the TransactionScope boundary.

Constructors

TryCatch()

Creates a new instance of the TryCatch() class.

Properties

(Inherited from Activity)
CanInduceIdle

Gets or sets a value that indicates whether the activity can cause the workflow to become idle.

(Inherited from NativeActivity)
Catches

The collection of Catch elements to be checked when the Try activity throws an exception.

Constraints

Gets a collection of Constraint activities that can be configured to provide validation for the Activity.

(Inherited from Activity)
DisplayName

Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking.

(Inherited from Activity)

The execution logic of the activity.

(Inherited from NativeActivity)
ImplementationVersion

Gets or sets the implementation version of the activity.

(Inherited from NativeActivity)
Try

The activity first executed when the TryCatch executes.

Variables

The collection of contained variables.

Methods

Abort(NativeActivityAbortContext)

When implemented in a derived class, takes actions in response to the activity being aborted.

(Inherited from NativeActivity)
CacheMetadata(NativeActivityMetadata)

Creates and validates a description of the activity's arguments, variables, child activities, and activity delegates.

(Inherited from NativeActivity)
Cancel(NativeActivityContext)

When implemented in a derived class, runs logic to cause graceful early completion of the activity.

(Inherited from NativeActivity)
Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
Execute(NativeActivityContext)

When implemented in a derived class, runs the activity's execution logic.

(Inherited from NativeActivity)
GetHashCode()

Serves as the default hash function.

(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)
OnCreateDynamicUpdateMap(NativeActivityUpdateMapMetadata, Activity)

Raises an event when creating a map for the dynamic update.

(Inherited from NativeActivity)
OnCreateDynamicUpdateMap(UpdateMapMetadata, Activity)

Raises an event when creating a map for the dynamic update.
