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();
        }
    }
}
