此方法应用到的对象。

返回值（RetVal）

类型： 字典

对象的扩展字典。

言论

如果对象没有扩展字典，此方法将为该对象创建一个新的扩展字典，并在返回值中返回它。

可以使用该属性查询对象以查看它是否具有扩展字典。HasExtensionDictionary

例子

VBA：

Sub Example_GetExtensionDictionary()
    ' This example creates a Circle object in model space and
    ' adds a new Extension Dictionary to the Circle object
    
    Dim EDictionary As AcadDictionary
    Dim circleObj As AcadCircle
    Dim centerPoint(0 To 2) As Double
    Dim radius As Double
    
    ' Define the Circle object
    centerPoint(0) = 0: centerPoint(1) = 0: centerPoint(2) = 0
    radius = 5#
    
    ' Create the Circle object in model space
    Set circleObj = ThisDrawing.ModelSpace.AddCircle(centerPoint, radius)

    ThisDrawing.Application.ZoomAll
    
    MsgBox "Circle object Extension Dictionary state before: " & circleObj.HasExtensionDictionary
    
    ' Create an Extension Dictionary for the new Circle
    Set EDictionary = circleObj.GetExtensionDictionary
    
    MsgBox "Circle object Extension Dictionary state after: " & circleObj.HasExtensionDictionary
End Sub

    ;; Create an Extension Dictionary for the new Circle
    (setq EDictionary (vla-GetExtensionDictionary circleObj))

    (alert (strcat "Circle object Extension Dictionary state after: " (if (= (vla-get-HasExtensionDictionary circleObj) :vlax-true) "True" "False")))
