The dcom sample demonstrates how to call a com object implemented in a windows service from multiple clients running on different computers 本dcom示例演示了如何从运行于不同计算机上的多个客户端调用在windows服务中实现的com对象。
When a managed client calls a com object , the runtime maps the com object s failure hresults to exceptions , which the marshaler throws on return from the call 当托管客户端调用com对象时,运行库将com对象的指示失败的hresult映射为异常,封送拆收器在从调用返回时引发该异常。
