首先是飞诗在问了一个问题:Acad2007的com包围盒无法正确获取文字的包围盒,问有没有其他方法?
但是他测试了lisp的获取是正确的,所以他想反射调用里面内置的,而他会反射,但是获取不到在参数传回返回值.
而edata解决了这个问题,然后我测试的时候发现net5桌面程序不能用:Marshal.GetActiveObject
真是一个问题接一个.....这可怎么呢?
虽然我在学net5的教学中知道了这个,但是它没有给我解决方案.
然后南胜提醒了我一下,有using Microsoft.VisualBasic.Interaction.CreateObject可以用.
为此我完成了之前没有完成的东西:com启动Acad
写一个net5的控制台调用这个,当然了,你喜欢低版本也可以...
new ReflectionAcad().GetBoundingBox();
然后复制粘贴这个就好了,各种的com技术都蛮有意思的.
