定义

命名空间:

System.Activities.Presentation.Expressions

程序集:

System.Activities.Presentation.dll

返回表达式的尝试此时是否为 morph。

public:
 abstract bool TryMorphExpression(System::Activities::ActivityWithResult ^ expression, bool isLocationExpression, Type ^ newType, System::Activities::Presentation::EditingContext ^ context, [Runtime::InteropServices::Out] System::Activities::ActivityWithResult ^ % newExpression);

public abstract bool TryMorphExpression (System.Activities.ActivityWithResult expression, bool isLocationExpression, Type newType, System.Activities.Presentation.EditingContext context, out System.Activities.ActivityWithResult newExpression);

abstract member TryMorphExpression : System.Activities.ActivityWithResult * bool * Type * System.Activities.Presentation.EditingContext * ActivityWithResult -> bool

Public MustOverride Function TryMorphExpression (expression As ActivityWithResult, isLocationExpression As Boolean, newType As Type, context As EditingContext, ByRef newExpression As ActivityWithResult) As Boolean
