NativeActivity<TResult>.Execute(NativeActivityContext) NativeActivity<TResult>.Execute(NativeActivityContext) NativeActivity<TResult>.Execute(NativeActivityContext) NativeActivity<TResult>.Execute(NativeActivityContext) Method

Definition

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

protected:
 abstract void Execute(System::Activities::NativeActivityContext ^ context);
protected abstract void Execute (System.Activities.NativeActivityContext context);
abstract member Execute : System.Activities.NativeActivityContext -> unit
Protected MustOverride Sub Execute (context As NativeActivityContext)

Parameters

context
NativeActivityContext NativeActivityContext NativeActivityContext NativeActivityContext

The execution context in which the activity executes.

Examples

The following code sample demonstrates using Execute in a class that inherits from NativeActivity<TResult>. This example is from the Non-Generic ParallelForEach sample.

protected override void Execute(NativeActivityContext context)
{
    IEnumerable values = this.Values.Get(context);
    if (values == null)
    {
        throw new InvalidOperationException("ParallelForEach requires a non-null Values argument.");
    }

    IEnumerator valueEnumerator = values.GetEnumerator();

    CompletionCallback onBodyComplete = new CompletionCallback(OnBodyComplete);
    while (valueEnumerator.MoveNext())
    {
        if (this.Body != null)
        {
            context.ScheduleAction(this.Body, valueEnumerator.Current, onBodyComplete);
        }
    }
    IDisposable disposable = valueEnumerator as IDisposable;
    if (disposable != null)
    {
        disposable.Dispose();
    }
}
