c#控制台应用程序，使用变量命名进程

本文关键字：变量 进程 控制台 应用程序 | 更新日期: 2023-09-27 18:08:03

我有一个c#控制台应用程序，它为15台数码相机创建了一个进程，可以根据命令拍摄和下载照片。目前，它是为16个相机硬编码的，我想让它向用户询问相机的数量，然后创建这个数量的进程/连接。

下面是连接3个摄像头的代码示例:

    Process takePic2;
    takePic2 = new Process();
    takePic2.StartInfo.UseShellExecute = false;
    //takePic2.StartInfo.RedirectStandardOutput = true;
    takePic2.StartInfo.RedirectStandardInput = true;
    takePic2.StartInfo.FileName = chdkLocation;
    string config2 = @"-i -c""-d=''.'libusb0%-0002%-%-0x04a9%-0x3248""";
    takePic2.StartInfo.Arguments = string.Format(config2);
    takePic2.Start();
    StreamWriter sw2 = takePic2.StandardInput;
    //sw2.WriteLine("list");
    sw2.WriteLine("rec");
    //sw2.WriteLine("shoot");
    Process takePic3;
    takePic3 = new Process();
    takePic3.StartInfo.UseShellExecute = false;
    //takePic3.StartInfo.RedirectStandardOutput = true;
    takePic3.StartInfo.RedirectStandardInput = true;
    takePic3.StartInfo.FileName = chdkLocation;
    string config3 = @"-i -c""-d=''.'libusb0%-0003%-%-0x04a9%-0x3248""";
    takePic3.StartInfo.Arguments = string.Format(config3);
    takePic3.Start();
    StreamWriter sw3 = takePic3.StandardInput;
    //sw3.WriteLine("list");
    sw3.WriteLine("rec");
    //sw3.WriteLine("shoot");
    Process takePic4;
    takePic4 = new Process();
    takePic4.StartInfo.UseShellExecute = false;
    //takePic4.StartInfo.RedirectStandardOutput = true;
    takePic4.StartInfo.RedirectStandardInput = true;
    takePic4.StartInfo.FileName = chdkLocation;
    string config4 = @"-i -c""-d=''.'libusb0%-0004%-%-0x04a9%-0x3248""";
    takePic4.StartInfo.Arguments = string.Format(config4);
    takePic4.Start();
    StreamWriter sw4 = takePic4.StandardInput;
    //sw4.WriteLine("list");
    sw4.WriteLine("rec");
    //sw4.WriteLine("shoot");

，这里是获取图片并下载它们的代码:

    while (true)
    {
        Console.WriteLine("type shoot to take a picture:"); // Prompt
        string commandInput = Console.ReadLine(); // Get string from user
        if (commandInput == "s")
        {
            sw1.WriteLine("shoot");
            sw2.WriteLine("shoot");
            sw3.WriteLine("shoot");
            sw4.WriteLine("shoot");
            sw5.WriteLine("shoot");
            sw6.WriteLine("shoot");
            sw7.WriteLine("shoot");
            sw8.WriteLine("shoot");
            sw9.WriteLine("shoot");
            sw10.WriteLine("shoot");
            sw11.WriteLine("shoot");
            sw12.WriteLine("shoot");
            sw13.WriteLine("shoot");
            sw14.WriteLine("shoot");
            sw15.WriteLine("shoot");
            sw16.WriteLine("shoot");
        }
        if (commandInput == "dl")
        {
            sw1.WriteLine("imdl -ddir=/HDimages/camera1/ -rm");
            sw2.WriteLine("imdl -ddir=/HDimages/camera2/ -rm");
            sw3.WriteLine("imdl -ddir=/HDimages/camera3/ -rm");
            sw4.WriteLine("imdl -ddir=/HDimages/camera4/ -rm");
            sw5.WriteLine("imdl -ddir=/HDimages/camera5/ -rm");
            sw6.WriteLine("imdl -ddir=/HDimages/camera6/ -rm");
            sw7.WriteLine("imdl -ddir=/HDimages/camera7/ -rm");
            sw8.WriteLine("imdl -ddir=/HDimages/camera8/ -rm");
            sw9.WriteLine("imdl -ddir=/HDimages/camera9/ -rm");
            sw10.WriteLine("imdl -ddir=/HDimages/camera10/ -rm");
            sw11.WriteLine("imdl -ddir=/HDimages/camera11/ -rm");
            sw12.WriteLine("imdl -ddir=/HDimages/camera12/ -rm");
            sw13.WriteLine("imdl -ddir=/HDimages/camera13/ -rm");
            sw14.WriteLine("imdl -ddir=/HDimages/camera14/ -rm");
            sw15.WriteLine("imdl -ddir=/HDimages/camera15/ -rm");
            sw16.WriteLine("imdl -ddir=/HDimages/camera16/ -rm");
        }
    }

我已经让它向用户询问要连接的相机的数量，并为该数字创建了一个for循环。我的问题是我如何设置进程名递增与循环I变量，所以它将是"进程takepic+ camerannumber"

    Console.WriteLine("Enter number of cameras:"); // Prompt
    string inputCameraQuantity = Console.ReadLine(); // Get string from user
    int cameraQuantity = Convert.ToInt32(inputCameraQuantity);
    string chdkLocation = @"C:'scancode'chdk'chdkptp.exe";
    for (int i = 1; i <= cameraQuantity; i++)
    {
        string cameranumber = Convert.ToString(i);
        Process takepic;
        //Process takepic+cameranumber;
        takepic = new Process();
        takepic.StartInfo.UseShellExecute = false;
        takepic.StartInfo.RedirectStandardInput = true;
        takepic.StartInfo.FileName = chdkLocation;
        if (cameraQuantity < 10)
        {
            cameranumber = "0" + Convert.ToString(i);
        }
        else { cameranumber = Convert.ToString(i); }
        string configA = @"-i -c""-d=''.'libusb0%-000";
        string configB = @"%-%-0x04a9%-0x3248""";
        string configC = configA + cameranumber + configB;
    }

c#控制台应用程序，使用变量命名进程

你不能。相反，你可以把它放到List中。

 var Cameras = new List<Process>()
 for (int i = 1; i <= cameraQuantity; i++)
    {
        Process takepic;
        //Process takepic+cameranumber;
        takepic = new Process();
        Cameras.Add(takepic);

那么你可以通过

得到它们
Cameras[0]. //whatever

或

如果你想给它们命名，把它们放在字典里

var Cameras = new Dictionary<string, Process>()
     for (int i = 1; i <= cameraQuantity; i++)
            {
                Process takepic;
                //Process takepic+cameranumber;
                takepic = new Process();
                Cameras.Add("takepic"+cameranumber, takepic);

然后得到它们

Cameras["takepic1"]. // whatever
