T:System.Activities.Statements.ForEach is similar to the keyword foreach, but is implemented as an activity rather than a language statement. Note that unlike foreach in C#, the ForEach<T> activity uses M:System.Collections.IEnumerable`1.GetEnumerator, rather than M:System.Collections.IEnumerator#System#Collections#IEnumerable#GetEnumerator.
The following code sample demonstrates creating a ForEach<T> activity. This example is from the DynamicActivity Creation sample.
new ForEach<int> { Values = new ArgumentValue<IEnumerable<int>> { ArgumentName = "Numbers" }, Body = new ActivityAction<int> { Argument = iterationVariable, Handler = new Assign<int> { To = accumulator, Value = new InArgument<int>(env => iterationVariable.Get(env) + accumulator.Get(env)) } } },
