Autodesk.Revit.UI.ContextualHelpType

Autodesk.Revit.UI.ContextualHelpType是Revit API中定义的枚举类型，用于指定上下文帮助的类型。

该枚举类型包含以下成员：

None：没有上下文帮助。
WhatsThis：使用何必为命令提供上下文帮助。

使用示例

下面的代码为项目浏览器中的“剖面”命令添加上下文帮助：

UIDocument uidoc = commandData.Application.ActiveUIDocument;
RevitCommandId cmdId = RevitCommandId.LookupPostableCommandId(PostableCommand.Section);
uidoc.PromptForContextualHelp(cmdId, Autodesk.Revit.UI.ContextualHelpType.WhatsThis);
