An activity that demarcates a transaction boundary.

public ref class TransactionScope sealed : System::Activities::NativeActivity

[System.Windows.Markup.ContentProperty("Body")]
public sealed class TransactionScope : System.Activities.NativeActivity

[<System.Windows.Markup.ContentProperty("Body")>]
type TransactionScope = class
    inherit NativeActivity

Public NotInheritable Class TransactionScope
Inherits NativeActivity

Inheritance: Object

Activity

NativeActivity
TransactionScope

Attributes: ContentPropertyAttribute

Examples

The following code sample demonstrates creating a TransactionScope activity.

new TransactionScope
{
    Body = new Sequence
    {
        Activities =
        {
            new WriteLine { Text = "    Begin TransactionScope" },

            new PrintTransactionId(),

            new TransactionScopeTest(),

            new WriteLine { Text = "    End TransactionScope" },
        },
    },
},

Remarks

When this activity begins executing, a new Transaction is started if one does not already exist. The transaction commits when the activity and all other participants in the transaction have completed successfully.

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

TransactionScope()

Initializes a new instance of the TransactionScope class.

Properties

AbortInstanceOnTransactionFailure	Gets or sets the value that indicates whether the workflow should be aborted if the transaction aborts.
Body	Gets or sets the activity that is scheduled when the TransactionScope executes.
CacheId	Gets the identifier of the cache that is unique within the scope of the workflow definition. (Inherited from Activity)
CanInduceIdle	Gets or sets a value that indicates whether the activity can cause the workflow to become idle. (Inherited from NativeActivity)
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)
Id	Gets an identifier that is unique in the scope of the workflow definition. (Inherited from Activity)
Implementation	The execution logic of the activity. (Inherited from NativeActivity)
ImplementationVersion	Gets or sets the implementation version of the activity. (Inherited from NativeActivity)
IsolationLevel	Gets or sets the IsolationLevel for this TransactionScope.
Timeout	Gets or sets the TimeSpan that indicates the timeout period for the transaction used for this TransactionScope.

Methods

Abort(NativeActivityAbortContext)	When implemented in a derived class, takes actions in response to the activity being aborted. (Inherited from NativeActivity)
CacheMetadata(ActivityMetadata)	Not implemented. Use the CacheMetadata(NativeActivityMetadata) method instead. (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. (Inherited from NativeActivity)
ShouldSerializeDisplayName()	Indicates whether the DisplayName property should be serialized. (Inherited from Activity)
ShouldSerializeIsolationLevel()	Indicates whether the IsolationLevel for this TransactionScope should be serialized.
ShouldSerializeTimeout()	Indicates whether the Timeout for this TransactionScope should be serialized.
ToString()	Returns a String that contains the Id and DisplayName of the Activity. (Inherited from Activity)
UpdateInstance(NativeActivityUpdateContext)	Updates the instance of NativeActivity. (Inherited from NativeActivity)
