设置 AutoCAD 首选项 （.NET）

AutoCAD .NET API 不包含任何用于访问通过“AutoCAD 选项”对话框访问的选项的类或方法。对这些选项的访问是通过 ActiveX®自动化库完成的。使用从应用程序对象的属性返回的 COM 对象。Preferences

拥有首选项 COM 对象后，可以访问与选项相关的九个对象，每个对象代表“选项”对话框中的一个选项卡。这些对象提供对“选项”对话框中所有注册表存储选项的访问。您可以使用在这些对象上找到的特性来自定义许多 AutoCAD 设置。这些对象是

• 首选项显示
• 首选项起草
• 首选项文件
• 首选项打开保存
• 首选项输出
• 首选项配置文件
• 首选项选择
• 首选项系统
• 首选项用户

访问首选项对象

下面的示例演示如何通过 COM 互操作访问首选项对象。

Dim acPrefComObj As AcadPreferences = Application.Preferences

AcadPreferences acPrefComObj = (AcadPreferences)Application.Preferences;

Dim acadPref as AcadPreferences
Set acadPref = ThisDrawing.Application.Preferences

引用“首选项”对象后，可以使用“显示”、“绘图”、“文件”、“打开保存”、“输出”、“配置文件”、“选择”、“系统”和“用户”属性访问任何特定的“首选项”对象。
