手头有一个PCI通讯板卡。有DLL驱动。测试DEMO原来是VC环境下。现在要改成c#环境。这里面涉及到C#如何调用原来DLL的API函数问题。任务单一：就是把原来的VC环境的demo程序用C#写。下面是VC环境的DEMO程序。<br />// Test_pcitio.cpp<br />//<br />// Generated by DriverWizard version DriverStudio 2.7.0 (Build 562)<br />//<br />// This console application demonstrates how to open a handle<br />// to a device in your driver, and communicate with the driver<br />// using Read, Write, and DeviceIoControl calls, as appropriate.<br />//<br />// This test program attempts to open the device using the<br />// GUID defined in "..PcitioDeviceinterface.h"<br /><br />#include <stdlib.h><br />#include <stdio.h><br />#include <windows.h><br /><br /><br />#include <winioctl.h><br />#include "..pcitioioctl.h"<br /><br />#include "..PcitioDeviceinterface.h" // Has class GUID definition<br /><br /><br /><br /><br />// This function is found in module OpenByIntf.cpp<br />HANDLE OpenByInterface(GUID* pClassGuid, DWORD instance, PDWORD pError);<br /><br />typedef void VOIDFUNC();<br /><br />HANDLE h,IOWaiter, hEvent;<br />// Prototypes<br />void Usage(void);<br />void ShowIoctlValues(void);<br /><br />// TODO:<br />// You can redefine the IOCTL handler prototypes as needed, adding<br />// appropriate parameters that can be collected from the command line.<br />// To do this you must modify the command line parsing logic.
