Creates an activity to do synchronous or asynchronous batch work that can use COM+ services without needing to create a COM+ component. This class cannot be inherited.

public ref class Activity sealed

[System.Runtime.InteropServices.ComVisible(false)]
public sealed class Activity

[<System.Runtime.InteropServices.ComVisible(false)>]
type Activity = class

Public NotInheritable Class Activity

Inheritance: Object
Activity

Attributes: ComVisibleAttribute

Examples

The following code example demonstrates how to use the Activity class and use the synchronization service.

class SvcClass: IServiceCall
{
    static int callNumber = 0;
    public void OnCall()
    {
        callNumber++;
        System.Guid contextID = ContextUtil.ContextId;
        Console.WriteLine("This is call number "+ callNumber.ToString());
        Console.WriteLine(contextID.ToString());
        System.TimeSpan sleepTime = new System.TimeSpan(0,0,0,10);
        System.Threading.Thread.Sleep(sleepTime);
    }
}
class EnterpriseServicesActivityClass
{
    [STAThread]
static void Main(string[] args)
    {
        ServiceConfig serviceConfig = new ServiceConfig();
        serviceConfig.Synchronization = SynchronizationOption.Required;
        serviceConfig.ThreadPool = ThreadPoolOption.MTA;
        SvcClass serviceCall = new SvcClass();
    Activity activity = new Activity(serviceConfig);
        activity.AsynchronousCall(serviceCall);
        activity.AsynchronousCall(serviceCall);
        Console.WriteLine("Waiting for asynchronous calls to terminate");
        Console.Read();
    }
}

Remarks

The context associated with the activity is completely determined by a ServiceConfig object.

Constructors

Activity(ServiceConfig)

Initializes a new instance of the Activity class.

Methods

AsynchronousCall(IServiceCall)	Runs the specified user-defined batch work asynchronously.
BindToCurrentThread()	Binds the user-defined work to the current thread.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
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)
SynchronousCall(IServiceCall)	Runs the specified user-defined batch work synchronously.
ToString()	Returns a string that represents the current object. (Inherited from Object)
UnbindFromThread()	Unbinds the batch work that is submitted by the SynchronousCall(IServiceCall) or AsynchronousCall(IServiceCall) methods from the thread on which the batch work is running.
