如何用C#激活SolidWorks插件“FeatureWorks”？

Question

我正在用 C# 构建一个使用 SolidWorks API 的程序。

当我使用以下命令创建 SolidWorks 的新实例时：

sldWrks = (SldWorks)Activator.CreateInstance(Type.GetTypeFromProgID("SldWorks.Application"));

应用程序已加载，但加载项未加载。
具体来说，我对该程序感兴趣的插件是 FeatureWorks。

如何让 SolidWorks 在插件处于活动状态时启动？
我是否需要在 SolidWorks 安装文件夹中的某个文本文件中设置选项或者修改注册表项？

你必须通过调用来加载它：

swApp.LoadAddIn(FileName);

这是 SolidWorks 的文档。

以下是我打开 PDM 插件的方法。我确信它会类似于FeatureWorks。这里使用的是 C# Windows 窗体应用程序（因此 MessageBox 调用）。希望这足以让您弄清楚其余的事情。

private SldWorks.SldWorks ConnectToSW()
    {
        SldWorks.SldWorks swApp = null;

        try
        {
            //try to connect to an existing open instance of SolidWorks:
            swApp = (SldWorks.SldWorks)Marshal.GetActiveObject("SldWorks.Application");
        }
        catch (Exception)
        {
            //try to open a new instance:
            try
            {
                swApp = new SldWorks.SldWorks();
            }
            catch (Exception ex)
            {
                MessageBox.Show("Can't connect to SolidWorks and can't open a new SolidWorks instance.\n" + ex.Message, "Error connecting to SolidWorks", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                return null;
            }
        }
        swApp.Visible = true;

        //now also try to make sure PDM add-in is enabled:
        try
        {
            string appPath = swApp.GetExecutablePath();
            appPath = appPath.Substring(0, appPath.LastIndexOf('\\')) + "\\SOLIDWORKS PDM";    //e.g. C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS -> C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS PDM

            string pdmAddinPath1 = $"{appPath}\\PDMSW.dll";
            string pdmAddinPath2 = $"{appPath}\\epdmlib.dll";

            //try the first addin dll
            if (!File.Exists(pdmAddinPath1))
            {
                DialogResult dlgRes = MessageBox.Show($"Can't load the PDM add-in:\n\n{pdmAddinPath1}\n\nPlease manually turn on the PDM Add-in in SolidWorks and click OK to continue", "Enable PDM Manually", MessageBoxButtons.OKCancel, MessageBoxIcon.Information);
                if (dlgRes == DialogResult.Cancel) throw new Exception();
            }
            try
            {
                swApp.LoadAddIn(pdmAddinPath1);
            }
            catch (Exception)
            {
                throw;
            }

            // try the second addin dll
            if (!File.Exists(pdmAddinPath2))
            {
                DialogResult dlgRes = MessageBox.Show($"Can't load the PDM add-in:\n\n{pdmAddinPath2}\n\nPlease manually turn on the PDM Add-in in SolidWorks and click OK to continue", "Enable PDM Manually", MessageBoxButtons.OKCancel, MessageBoxIcon.Information);
                if (dlgRes == DialogResult.Cancel) throw new Exception();
            }
            Cursor.Current = Cursors.WaitCursor;
            try
            {
                swApp.LoadAddIn(pdmAddinPath2);
            }
            catch (Exception)
            {
                throw;
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show($"Couldn't load the PDM addin.  Nothing about this is going to work right.\n\n{ex.Message}", "PDM Add-in not found", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
            //return null;
        }

        return swApp;
    }
