C# SolidWorks 二次开发 API —Solidworks的多开操作与连接指定版本Solidworks

        今天有网友问我关于如何用Exe操作多个Solidworks的问题，其实之前我看到过解决方案，是通过进程和id获取，而不是我们平时常用的 (SldWorks)Marshal.GetActiveObject(“SldWorks.Application.27”);

        所以晚上回来查了些资料，发现了有了解决方案，我精简了一下，做了个dll.大家可以试试。    

 ''' <summary>
    ''' 创建一个新的Solidworks并返回实例
    ''' </summary>
    ''' <param name="version">指定版本号，-1表示默认.</param>
    ''' <param name="suppressDialogs">True 则禁用solidworks弹出消息.</param>
    ''' <param name="requireMainWindow">True 表示运行完显示到主窗口</param>
    ''' <param name="startProcessTimeout">返回Null 如果SolidWorks在指定时间内没有打开。</param>
    ''' <param name="createWindowTimeout">返回Null 如果SolidWorks主窗口在指定时间内没有显示.</param>
    ''' <returns></returns>
    Public Shared Function RunSolidWorks(version As Integer,
                                         visible As Boolean,
                                         Optional suppressDialogs As Boolean = False,
                                         Optional requireMainWindow As Boolean = True,
                                         Optional startProcessTimeout As Integer = 30,
                                         Optional createWindowTimeout As Integer = 15) As SldWorks

        Dim executablePath As String = CTFileSystem.GetSolidWorksExecutablePath(version)

        If File.Exists(executablePath) = False Then Return Nothing

        Dim info As ProcessStartInfo = New ProcessStartInfo(executablePath)

        If suppressDialogs Then info.Arguments = "/r"

        Dim process As Process = Process.Start(info)
        Dim app As SldWorks = Nothing
        Dim t As DateTime = DateTime.Now

        While app Is Nothing
            Threading.Thread.Sleep(1000)
            If Math.Abs(DateTime.Now.Subtract(t).Seconds) > startProcessTimeout Then Return Nothing

            'If it were possible to get a GUID from a process ID then we could use GetActiveObject instead of this
            app = GetComObjectFromProcessId(process.Id)
        End While

        t = DateTime.Now
        While IsRunning(isMainWindowCreated:=True) = False
            Threading.Thread.Sleep(1000)
            If Math.Abs(DateTime.Now.Subtract(t).Seconds) > createWindowTimeout Then Return Nothing
        End While

        If visible = False Then
            Dim frame As Frame = app.Frame()
            If frame Is Nothing Then Return app
            Dim handle As IntPtr = frame.GetHWndx64()
            If ShowWindow(handle, 0) Then Return app
        End If

        Return app
    End Function

我刚刚进行了测试，用起来比较简单。我用代码新建了两个solidworks 2018窗口：

        private SldWorks sldWorks2018_1 = null;
        private SldWorks sldWorks2018_2 = null;

        private void button1_Click(object sender, EventArgs e)
        {
            sldWorks2018_1 = PStandAlone.RunSolidWorks(26, true, false, false, 30, 15);
        }

        private void button2_Click(object sender, EventArgs e)
        {
            sldWorks2018_2 = PStandAlone.RunSolidWorks(26, true, false, false, 30, 15);
        }

        private void button3_Click(object sender, EventArgs e)
        {
            sldWorks2018_1.SendMsgToUser("From 2018 -1");
            sldWorks2018_2.SendMsgToUser("From 2018 -2");
        }
