在C#中,不直接操作内存地址或者直接调用Windows API函数,而是通常使用封装好的类库或者P/Invoke来调用外部函数。因此,这段代码的转换会涉及到一些假设,特别是关于外部调用的处理。下面是一个可能的转换:

using System;
using System.Runtime.InteropServices;

public static class GGCAM
{
    private static IntPtr camHandle = IntPtr.Zero;
    private static bool isInitialized = false;
    private static int lastInitResult = 0;

    [DllImport("SomeExternalDLL.dll", CallingConvention = CallingConvention.StdCall)]
    private static extern IntPtr CreateGGCameraHandle();

    [DllImport("SomeExternalDLL.dll", CallingConvention = CallingConvention.StdCall)]
    private static extern bool GetVideoDeviceNum(IntPtr handle, out int num);

    [DllImport("SomeExternalDLL.dll", CallingConvention = CallingConvention.StdCall)]
    private static extern bool SubFunction(int param1, int param2, int param3);

    public static int InitDevice()
    {
        Log("CGGCAM_InitDevice-start");
        camHandle = CreateGGCameraHandle();
        if (camHandle == IntPtr.Zero)
        {
            Log("camHandle == NULL");
            isInitialized = false;
            return 0;
        }

        if (SubFunction(2760, 13168, 0) && SubFunction(3141, 25408, 0))
        {
            lastInitResult = 6;
        }
        else if (SubFunction(11674, 25344, 4626) &&
                 SubFunction(11674, 25360, 4102) &&
                 SubFunction(11674, 25376, 8197))
        {
            lastInitResult = 9;
        }
        else if (SubFunction(5075, 21525, 0))
        {
            lastInitResult = 888;
        }
        else
        {
            isInitialized = false;
            Log("Initialization failed in an unknown way.");
            return 0;
        }

        isInitialized = true;
        Log($"CGGCAM_InitDevice-end, {lastInitResult}");
        return lastInitResult;
    }

    public static int GetTotalDeviceNum()
    {
        Log("CGGCAM_GetTotalDeviceNum-start");
        if (!isInitialized)
        {
            Log("CAM not init");
            return 0;
        }

        int totalNum = 0;
        GetVideoDeviceNum(camHandle, out totalNum);
        Log($"CGGCAM_GetTotalDeviceNum-end, total={totalNum}");
        return totalNum;
    }

    private static void Log(string message)
    {
        // Implement logging mechanism here
        Console.WriteLine(message);
    }
}

在这个转换中,我做了以下假设和调整:
①外部函数调用:我使用了DllImport来声明外部函数(CreateGGCameraHandle, GetVideoDeviceNum, 和一个假定的 SubFunction 代表 sub_10002BC0)。这些函数的确切声明可能需要根据实际的DLL和函数签名进行调整。
②日志记录:原始代码中的sub_10003350函数似乎用于日志记录。在C#中,我创建了一个简单的Log方法来模拟这个行为,但实际上你可能需要根据你的应用程序的日志记录机制来实现它。
③全局变量:原始代码中使用的全局变量(如dword_101BE6D4和byte_101BE4CA)在C#版本中被转换为静态字段。
④类型转换和数据类型:C++代码中的某些数据类型和操作(如指针和类型转换)在C#中有所不同,因此在转换过程中进行了适当的调整。
请注意,由于缺少原始环境和完整上下文,这个转换可能需要进一步的调整才能完全符合实际需求。

写了一段句柄可以获取但是数量就是没有,因为是新手不知道是那错了。


public partial class Form1 : Form
    {
        private int hHwnd;
        [DllImport("CameraControl.dll", EntryPoint = "CreateGGCameraHandle", ExactSpelling = false, CallingConvention = CallingConvention.StdCall)]
        public static extern int CreateGGCameraHandle();

        [DllImport("CameraControl.dll", EntryPoint = "GetVideoDeviceNum", ExactSpelling = false, CallingConvention = CallingConvention.StdCall)]
        public static extern int GetVideoDeviceNum(int jj,int kk);

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
            hHwnd = CreateGGCameraHandle();
            MessageBox.Show(hHwnd.ToString());
        }

        private void button2_Click(object sender, EventArgs e)
        {
           int jkl = GetVideoDeviceNum(hHwnd, 0);
            MessageBox.Show(jkl.ToString());
        }
    }
