ConnectionPoint(ActivityDesigner, DesignerEdges, Int32) 构造函数

定义

使用指定的 ConnectionPointActivityDesigner 枚举值和整数初始化 DesignerEdges 类的新实例。Initializes a new instance of the ConnectionPoint class by using the specified ActivityDesigner, DesignerEdges enumeration value, and an integer.

public:
 ConnectionPoint(System::Workflow::ComponentModel::Design::ActivityDesigner ^ associatedDesigner, System::Workflow::ComponentModel::Design::DesignerEdges designerEdge, int connectionIndex);
public ConnectionPoint (System.Workflow.ComponentModel.Design.ActivityDesigner associatedDesigner, System.Workflow.ComponentModel.Design.DesignerEdges designerEdge, int connectionIndex);
new System.Workflow.ComponentModel.Design.ConnectionPoint : System.Workflow.ComponentModel.Design.ActivityDesigner * System.Workflow.ComponentModel.Design.DesignerEdges * int -> System.Workflow.ComponentModel.Design.ConnectionPoint
Public Sub New (associatedDesigner As ActivityDesigner, designerEdge As DesignerEdges, connectionIndex As Integer)

参数

associatedDesigner
ActivityDesigner

连接点所属的 ActivityDesignerThe ActivityDesigner to which the connection point belongs.

designerEdge
DesignerEdges

指定连接点在活动设计器上所处位置的 DesignerEdges 枚举值。The DesignerEdges enumeration value that specifies where on the activity designer the connection point is located.

connectionIndex
Int32

当前 ConnectionPoint 的索引位置。An index location of the current ConnectionPoint.

例外

connectionIndex 小于零。connectionIndex is less than zero.

- 或 --- or -- connectionIndex 大于或等于 associatedDesigner 上的连接点数。connectionIndex is greater than or equal to the number of connection points on associatedDesigner.

associatedDesigner 包含空引用(在 Visual Basic 中为 Nothing)。associatedDesigner contains a null reference (Nothing in Visual Basic).
