警告

此 API 現已淘汰。

表示 IfElseActivity 的分支。Represents a branch of an IfElseActivity. 這個類別無法被繼承。This class cannot be inherited.

注意

此資料討論已被汰換的類型及命名空間。This material discusses types and namespaces that are obsolete. 如需詳細資訊,請參閱 Windows Workflow Foundation 4.5 中即將淘汰的類型For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

會先決定每個分支的 ActivityCondition,再執行分支。The ActivityCondition of each branch is determined before the branch is run. 在評估為 IfElseBranchActivityIfElseActivity 中的第一個 true 已執行。The first IfElseBranchActivity in the IfElseActivity that evaluates to true is run.
