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

 

 public class ExecuteEvent : IExternalEventHandler
    {


        public string Name { get; private set; }

        public Action<UIApplication> ExecuteAction { get; set; }

        public ExecuteEvent(string name)
        {
            Name = name;
        }

        public void Execute(UIApplication app)
        {


            if (ExecuteAction != null)
            {
                try
                {
                    ExecuteAction(app);
                }
                catch
                { }
            }
        }

        public string GetName()
        {
            return Name;

        }
    }

private void Start_Click(object sender, EventArgs e)
        {
            if (ExternalEvent != null)
            {
                ExecuteEvent.ExecuteAction = new Action<UIApplication>((app) =>
                {
                    if (app.ActiveUIDocument == null || app.ActiveUIDocument.Document == null)
                        return;

                    UIApplication uiApp = cmdDataForm.Application;
                    Autodesk.Revit.ApplicationServices.Application application = uiApp.Application;
                    UIDocument uiDocument = uiApp.ActiveUIDocument;
                    Document document = uiDocument.Document;

                    object[,] length = { };

                    length = ReadExcel.Read(PathText.Text);

                    using (BottomSupport bottomSupport = new BottomSupport())
                    {   //创建底托
                        bottomSupport.CreateBottomSupport(document, length);
                    }
                    using (Vertical vertical = new Vertical())
                    {   //创建竖杆
                        vertical.CreateVertical(document, length);
                    }
                    using (NewRail newRail = new NewRail())
                    {   //创建纵向横杆
                        newRail.CreateRail(document, length);
                    }
                    using (Rail rail = new Rail())
                    {   //创建横杆
                        rail.CreateRail(document, length);
                    }

                    using (Diagonal diagonal = new Diagonal())
                    {   //创建斜杆
                        diagonal.CreateDiagonal(document, length);
                    }

                    using (Disc disc = new Disc())
                    {   //创建圆盘
                        disc.CreateDisc(document, length);
                    }
                    using (TopSupport topSupport = new TopSupport())
                    {   //创建顶托
                        topSupport.CreateTopSupport(document, length);
                    }

                    MessageBox.Show("OK了,可以去检查一下有没有错误了");

                });
                ExternalEvent.Raise();
            }
        }
