示例
下面的代码示例演示如何创建 SequenceActivity 类的新实例，并将 SequenceActivity 类添加到 ParallelActivity 类。 此代码示例是 WhileAndParallelWorkflow.Designer.cs 文件中 WhileAndParallel SDK 示例的一部分。 有关详细信息，请参阅 使用 While 和 Parallel。
this.WhileLoop = new System.Workflow.Activities.WhileActivity();
this.Parallel = new System.Workflow.Activities.ParallelActivity();
this.Sequence1 = new System.Workflow.Activities.SequenceActivity();
this.Sequence2 = new System.Workflow.Activities.SequenceActivity();
this.ConsoleMessage1 = new System.Workflow.Activities.CodeActivity();
this.ConsoleMessage2 = new System.Workflow.Activities.CodeActivity();
//
// WhileLoop
//
this.WhileLoop.Activities.Add(this.Parallel);
codecondition1.Condition += new System.EventHandler<System.Workflow.Activities.ConditionalEventArgs>(this.WhileCondition);
this.WhileLoop.Condition = codecondition1;
this.WhileLoop.Name = "WhileLoop";
//
// Parallel
//
this.Parallel.Activities.Add(this.Sequence1);
this.Parallel.Activities.Add(this.Sequence2);
this.Parallel.Name = "Parallel";
Me.WhileLoop = New System.Workflow.Activities.WhileActivity()
Me.Parallel = New System.Workflow.Activities.ParallelActivity()
Me.Sequence1 = New System.Workflow.Activities.SequenceActivity()
Me.Sequence2 = New System.Workflow.Activities.SequenceActivity()
Me.ConsoleMessage1 = New System.Workflow.Activities.CodeActivity()
Me.ConsoleMessage2 = New System.Workflow.Activities.CodeActivity()
'
' WhileLoop
'
Me.WhileLoop.Activities.Add(Me.Parallel)
AddHandler codecondition1.Condition, AddressOf Me.WhileCondition
Me.WhileLoop.Condition = codecondition1
Me.WhileLoop.Name = "WhileLoop"
'
' Parallel
'
Me.Parallel.Activities.Add(Me.Sequence1)
Me.Parallel.Activities.Add(Me.Sequence2)
Me.Parallel.Name = "Parallel"

SequenceActivity 是一种 CompositeActivity，这意味着 SequenceActivity 可以包含其他活动。
SequenceActivity 类以有序方式协调一组子活动的运行，一次一个。 完成最终子活动后，将完成 SequenceActivity。
派生自 SequenceActivity 的类不应实现 IActivityEventListener<T> 接口，否则派生类将无法正确执行。
