根据提供的引用内容，使用C#编写PCIE的Demo需要遵循以下步骤：1.连接好硬件后，烧录bit文件，安装PCIe内核驱动，然后重启计算机。2.打开VS工程，创建一个新的C#控制台应用程序项目。3.在项目中添加对C++ DLL的引用，以便在C#中调用C++ API。4.在C#代码中编写调用C++ API的代码，实现相机的连接、配置、图像读取、图像显示等功能。5.编译并运行C#应用程序，即可看到相机连接成功、拍摄图像正常。下面是一个简单的C#调用C++ DLL的例子，实现了对DLL中的函数的调用：using System;
using System.Runtime.InteropServices;namespace PciDemo
{class Program{[DllImport("PciDll.dll", CallingConvention = CallingConvention.Cdecl)]public static extern int ConnectCamera();[DllImport("PciDll.dll", CallingConvention = CallingConvention.Cdecl)]public static extern int ConfigureCamera();[DllImport("PciDll.dll", CallingConvention = CallingConvention.Cdecl)]public static extern int ReadImage();[DllImport("PciDll.dll", CallingConvention = CallingConvention.Cdecl)]public static extern int DisplayImage();static void Main(string[] args){int result = ConnectCamera();if (result == 0){Console.WriteLine("Camera connected successfully.");}else{Console.WriteLine("Failed to connect camera.");}result = ConfigureCamera();if (result == 0){Console.WriteLine("Camera configured successfully.");}else{Console.WriteLine("Failed to configure camera.");}result = ReadImage();if (result == 0){Console.WriteLine("Image read successfully.");}else{Console.WriteLine("Failed to read image.");}result = DisplayImage();if (result == 0){Console.WriteLine("Image displayed successfully.");}else{Console.WriteLine("Failed to display image.");}Console.ReadLine();}}
