C# TEKLA STRUCTURES 2022 二次开发 开发环境搭建

初步接触二次TEKLA，以下仅为个人观点

使用的exe方式开发的

引用的nuget包

程序入口点稍作处理,开启了TEKLA 软件才能启动本程序，TEKLA软件关闭，本程序退出

    internal static class Program
    {
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            try
            {
                if (TeklaStructures.Connect())
                {
                    TeklaStructures.Closed += (s, e) =>
                    {
                        Interaction.MsgBox("Tekla Structures程序已经退出！", MsgBoxStyle.OkOnly | MsgBoxStyle.Critical);
                        Application.Exit();
                    };
                    Application.EnableVisualStyles();
                    Application.SetCompatibleTextRenderingDefault(false);
                    Application.Run(new MainForm());
                }
                else
                {
                    Interaction.MsgBox("请先保证Tekla软件已经被启动！", MsgBoxStyle.OkOnly | MsgBoxStyle.Critical);
                    Application.Exit();
                }
            }
            catch (Exception ex)
            {
                Interaction.MsgBox(ex.StackTrace, MsgBoxStyle.OkOnly | MsgBoxStyle.Critical);
            }
        }
    }

主窗口采用反射搭建一个 固定的界面

效果如下

 

 

 

反射的特性标签自己定义的如下

 public class MyTeklaCmdAtt : Attribute
 {
     public string ImageName { get; set; }
     public string ButtonName { get; set; }
     public string CategoryName { get; set; }
     public string HelpString { get; set; }
     public MyTeklaCmdAtt(string _category, string _cmdName, string helpStr = "", string _img = "")
     {
         this.ImageName = _img;
         this.ButtonName = _cmdName;
         this.CategoryName = _category;
         this.HelpString = helpStr;
     }
 }

主界面代码如下

public partial class MainForm : ApplicationFormBase
 {
     public static Model MyModel { get; set; }
     public static ModelInfo ModelInfo => MyModel?.GetInfo();
     public MainForm()
     {
         this.InitializeComponent();
         if (MyModel == null) MyModel = new Model();
         base.AutoSize = true;
         base.InitializeForm();
         base.Size = this.Size;
         base.Text = Application.ProductName + $"({ModelInfo.ModelName})";
         Dialogs.SetSettings(string.Empty);
         TeklaStructures.MainWindow.AttachChildForm(this);
         //AllocConsole();
     }
     private void Form1_Load(object sender, EventArgs e)
     {
         var cls = System.Reflection.Assembly.GetExecutingAssembly().GetTypes().Where(c => c.IsClass && c.IsPublic);
         var Cmdmis = new List<MethodInfo>();
         foreach (var item in cls)
         {
             var mis = item.GetMethods().Where(m => m.IsPublic && m.IsStatic && m.GetCustomAttribute(typeof(MyTeklaCmdAtt)) != null);
             if (!mis.Any()) continue;
             Cmdmis.AddRange(mis.ToArray());
         }

         Dictionary<string, List<MethodInfo>> dicts = Cmdmis.GroupBy(m => m.DeclaringType.Name).ToDictionary(c => c.Key, c => c.ToList());
         foreach (var item in dicts)
         {
             var tabPage = new TabPage()
             {
                 //Anchor = AnchorStyles.Top | AnchorStyles.Left | AnchorStyles.Right,
                 Text = item.Key,
                 Name = $"tbPage_{item.Key}",
                 BorderStyle = BorderStyle.Fixed3D,
                 BackColor = Color.AliceBlue,     
                 //AutoSizeMode = AutoSizeMode.GrowOnly,
                 //AutoSize = true
             };
             var clsFlowLayoutPanel = new FlowLayoutPanel
             {
                 Name = $"flwPan_{item.Key}",
                 FlowDirection = FlowDirection.TopDown,
                 Padding = new Padding(3),
                 BorderStyle = BorderStyle.FixedSingle,
                 AutoSize = true,
                 Parent = tabPage,
                 Dock = DockStyle.Fill,
                 AutoScroll = true,
                 WrapContents = true
             };
             tabPage.Controls.Add(clsFlowLayoutPanel);
             foreach (var mi in item.Value)
             {
                 var att = mi.GetCustomAttribute<MyTeklaCmdAtt>();
                 var btn = new Button()
                 {
                     Name = $"btn_{att.ButtonName}",
                     Text = att.ButtonName,
                     FlatStyle = FlatStyle.Popup,
                     AutoSize = true
                 };
                 var tt1 = new System.Windows.Forms.ToolTip
                 {
                     IsBalloon = true,
                     BackColor = Color.LightYellow,
                     UseAnimation = true,
                 };
                 tt1.SetToolTip(btn, att.HelpString);
                 btn.Click += (s1, e1) =>
                 {
                     try
                     {
                         var frm = mi.GetParameters().FirstOrDefault();
                         mi.Invoke(null, (frm==null?null:new object[] { this }));
                     }
                     catch (Exception ex)
                     {
                         Interaction.MsgBox(ex.StackTrace, MsgBoxStyle.OkOnly | MsgBoxStyle.Exclamation);
                     }

                 };
                 clsFlowLayoutPanel.Controls.Add(btn);
             }
             this.tabControl1.TabPages.Add(tabPage);
         }
     }

 }

 开始码代码，今天分享一个在图纸界面画出折断线的代码
