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。
// Test_pcitio.cpp

// Generated by DriverWizard version DriverStudio 2.7.0 (Build 562)
//
// This console application demonstrates how to open a handle
// to a device in your driver, and communicate with the driver
// using Read, Write, and DeviceIoControl calls, as appropriate.
//
// This test program attempts to open the device using the
// GUID defined in "..PcitioDeviceinterface.h"
#include <stdlib.h>
#include <stdio.h>
#include <windows.h>
#include <winioctl.h>
#include "..pcitioioctl.h"
#include "..PcitioDeviceinterface.h" // Has class GUID definition
// This function is found in module OpenByIntf.cpp

void ShowIoctlValues(void);
// TODO:
// You can redefine the IOCTL handler prototypes as needed, adding
// appropriate parameters that can be collected from the command line.
// To do this you must modify the command line parsing logic. An
// example of this is shown in comments throughout the test application.

希望北京有谁熟悉，因为可以方便调试验证，时间很紧。希望周六就能搞定（做过的人大约1小时搞定）我的电话：010-80752670
