SolidWorks API和Winforms C#swApp(独立) [英] Solidworks API and Winforms C# swApp (Standalone)

问题描述

这是solidworks告诉您要做的对swApp的引用，但是我一直在引用它的行上得到NullReferenceException.

This is what solidworks tells you to do to reference swApp, but I keep getting NullReferenceException on the line that it is referenced.

有人知道为什么吗?或我该如何修理?

Does anyone have any idea why? or How I go about repairing?

我可以稍后引用它吗，例如swApp = ????

Can I reference it later on such as swApp = ????

private void button5_Click(object sender, EventArgs e)
{
    //Save Drawing
    ModelDoc2 swDoc = null;
    int longstatus = 0;
    swDoc = ((ModelDoc2)(swApp.ActiveDoc));
    longstatus = swDoc.SaveAs3(
            @"C:\Engineering\Engineering\SW Automation\Linear Actuator Technology\MLD Series\Prints\Configured Prints\" + 
            textBox1.Text + ".SLDDRW", 0, 2);
}

public SldWorks swApp;

推荐答案

想通了，谢谢大家的帮助.

Figured it out thanks for the help everyone.

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