Rect3D.IsEmpty Rect3D.IsEmpty Rect3D.IsEmpty Rect3D.IsEmpty Property

定義

取得值,這個值表示這個 Rect3D 是否為 EmptyRect3DGets a value that indicates whether this Rect3D is the EmptyRect3D.

public:
 property bool IsEmpty { bool get(); };
public bool IsEmpty { get; }
member this.IsEmpty : bool
Public ReadOnly Property IsEmpty As Boolean

屬性值

如果這個 Rect3D 是空矩形則為 true,否則為 falsetrue if this Rect3D is the empty rectangle; false otherwise.

備註

如果Size為零, 這Rect3D仍然包含一組零或1維的點; 因此, 不應該使用這個屬性來檢查零區域。If Size is zero, this Rect3D still contains a zero- or 1-dimensional set of points; therefore, this property should not be used to check for zero area.

Rect3D通常用來表示MeshGeometry3DModel3D的界限。Rect3D is typically used to represent the bounds of a MeshGeometry3D or Model3D.
