Description:

A looping activity that executes activities contained within it, once for each value provided in the Values collection.

Inheritance Hierarchy:

System.Object
  System.Activities.Activity
    System.Activities.NativeActivity
      System.Activities.Statements.ForEach<T>

Function:

Runs one or more activities once for each value within a specified collection of Values. The Body of the ForEach activity may be designed to sequentially process each value in the collection in a similar way.

In a Workflow:

The ForEach<T> activity could be used with the Query Task and Get Geometries activities as follows:

• Use the Query Task activity to obtain a feature set.
• Use the Get Geometries activity to extract those geometries from the feature set.
• Use the ForEach<T> activity to process each geometry.

Properties:

Name	Description
Display Name	ForEach<T> You can change the name of an activity to one that describes what it does. A descriptive name can make a workflow easier to interpret and maintain.

Values	The activity’s collection of input values for the execution of the Body activities.
Foreach	Activity-scoped variable name that references a single instance from the Values collection during each iteration of the loop.
