revit二次开发之winform无法执行事务

参考：

Revit二次开发——非模态窗口:https://blog.csdn.net/niuge8905/article/details/79767671

想用winform读取文件数据,直接使用却又提示无法执行事务模式,所以需要注册个事件

 1  public class ExecuteEvent : IExternalEventHandler
 2     {
 3 
 4 
 5         public string Name { get; private set; }
 6 
 7         public Action<UIApplication> ExecuteAction { get; set; }
 8 
 9         public ExecuteEvent(string name)
10         {
11             Name = name;
12         }
13 
14         public void Execute(UIApplication app)
15         {
16 
17 
18             if (ExecuteAction != null)
19             {
20                 try
21                 {
22                     ExecuteAction(app);
23                 }
24                 catch
25                 { }
26             }
27         }
28 
29         public string GetName()
30         {
31             return Name;
32 
33         }
34     }
