定义

命名空间:

System.Activities.Statements

程序集:

PickBranch 对象的集合，Pick 活动可能会基于传入的事件执行其中的一个活动。

public:
 property System::Collections::ObjectModel::Collection<System::Activities::Statements::PickBranch ^> ^ Branches { System::Collections::ObjectModel::Collection<System::Activities::Statements::PickBranch ^> ^ get(); };

public System.Collections.ObjectModel.Collection<System.Activities.Statements.PickBranch> Branches { get; }

member this.Branches : System.Collections.ObjectModel.Collection<System.Activities.Statements.PickBranch>

Public ReadOnly Property Branches As Collection(Of PickBranch)

属性值

Collection<PickBranch>

分支集合。

示例

下面的代码示例演示如何设置 Pick 活动的 Branches 属性。 此示例摘自 使用选取活动 示例。

static Activity CreateWF()
{
    Variable<string> name = new Variable<string>();
    Sequence body = new Sequence
    {
        Variables = { name },
        Activities =
        {
            new WriteLine { Text = "What is your name? (You have 5 seconds to answer)" },
            new Pick
            {
               Branches =
               {
                   new PickBranch
                    {
                       Trigger = new ReadString
                       {
                           Result = name,
                           BookmarkName = bookmarkName
                       },
                       Action = new WriteLine
                       {
                           Text = new InArgument<string>(env => "Hello " + name.Get(env))
                       }
                   },
                   new PickBranch
                    {
                       Trigger = new Delay
                       {
                           Duration = TimeSpan.FromSeconds(5)
                       },
                       Action = new WriteLine
                       {
                           Text = "Time is up."
                       }
                   }
               }
           }
       }
    };

    return body;
}
