保存层状态 （.NET）

使用该方法在图形中保存一组图层设置。该方法需要三个参数。第一个参数是命名要保存的图层状态的字符串。第二个参数用于标识要保存的图层属性。使用枚举的常量来标识要保存的图层设置。下表列出了属于枚举的常量。SaveLayerStateSaveLayerStateLayerStateMasksLayerStateMasks

将常量相加以指定多个属性。

所需的第三个参数是要保存其图层设置的视口的对象 ID。用于不指定视口。如果尝试将图层状态保存在已存在的名称下，则会返回错误。必须先重命名或删除现有图层状态，然后才能重复使用该名称。ObjectId.Null

保存图层的颜色和线型设置

以下代码将图形中当前图层的颜色和线型设置保存在名为 ColorLinetype 下。
