示例一：医疗保险系统对接的COM互操作：
保险系统接口规范提供PB调用示例：
//创建地纬嵌入式接口对象，调用com组件
int vi Oleobject sei
sei =create Oleobject //创建ole对象seiproxy
vi= sei.connecttonewobject('sei3') //连接com组件 if vi <> 0 then
messagebox('错误','创建地纬嵌入式接口sei对象失败！')
return end if
我们使用.NetFramework4.6.1调用方式：
Type type = Type.GetTypeFromProgID("sei3", true);
dynamic COM = Activator.CreateInstance(type);
使用同样的方式，在.NetCore3.1.4上运行返回异常：
Creating an instance of the COM component with CLSID {D5D8D5B2-CCD5-4EEC-BE61-0CA13A1940C7} from the IClassFactory failed due to the following error: ffffdf8f 0xFFFFDF8F.
Example 1: com interoperability of medical insurance system docking:
The insurance system interface specification provides Pb call examples:
//Create the ground latitude embedded interface object and call COM component
int vi Oleobject sei
SEI = create oleobject / / create OLE object seiproxy
vi= sei.connecttonewobject ('sei3 ') / / connect COM component if VI < > 0 then
MessageBox ('error ',' failed to create SEI object of ground latitude embedded interface! ')
return end if
We use. Netframework 4.6.1 to call:
Type type = Type.GetTypeFromProgID ("sei3", true);
dynamic COM = Activator.CreateInstance (type);
Using the same method, run return exception on. NETCORE 3.1.4:
Creating an instance of the COM component with CLSID {D5D8D5B2-CCD5-4EEC-BE61-0CA13A1940C7} from the IClassFactory failed due to the following error: ffffdf8f 0xFFFFDF8F.
