我来帮你搞定这个需求，要实现项目开机自动后台运行，咱们需要完成IIS部署和后台任务自动触发两个核心步骤，下面一步步来：

第一步：把项目部署到IIS服务器 #

1. 发布ASP.NET MVC项目

   • 在Visual Studio里右键项目，选择「发布」，目标选「IIS、FTP等」，可以先发布到本地文件夹，再把文件复制到IIS服务器对应的目录，也可以直接配置远程发布到IIS。
   • 确保发布包包含所有依赖项：比如加密工具类Rijndael128EncryptorDAO、读取用的文本文件（CapImgLoaction.txt、location1.txt等），以及项目的配置文件。

2. 在IIS中创建并配置网站

   • 打开IIS管理器，右键「网站」→「添加网站」，填写网站名称，选择物理路径为你发布的项目文件夹，设置访问端口（比如8080）。
   • 应用程序池要选对应版本的.NET Framework（比如你的项目用的是.NET 4.7.2，就选对应版本的池），并把池的启动模式设为「AlwaysRunning」，防止站点闲置回收。
   • 测试访问：在浏览器输入http://localhost:8080/FaceCompare，确认页面能正常加载。

第二步：实现开机自动后台运行（无需手动点击启动） #

你的项目目前需要手动点击「Start」按钮触发FaceCompare接口，要实现后台自动运行，这里给你两种实用方案：

方案1：用Windows任务计划程序定时调用接口（无需改代码） #

这是最省心的方式，不用动项目代码：

1. 打开「Windows任务计划程序」，点击「创建基本任务」，设置任务名称比如「人脸比对自动执行」。
2. 触发器选择「计算机启动时」，或者按你需要的频率（比如每分钟执行一次）设置重复触发。
3. 操作选择「启动程序」，程序选powershell，参数填：

   Invoke-WebRequest -Uri "http://localhost:8080/FaceCompare/FaceCompare" -Method Post
   

4. 最后设置任务的执行账户为有权限访问IIS和读取项目文件的账户，确保任务能正常执行。

方案2：修改项目代码，内置后台定时任务 #

如果不想依赖外部任务，可以把比对逻辑改成内置后台服务：

1. 先把业务逻辑抽离成独立服务类，避免和控制器耦合：

public class FaceComparisonService
{
    private readonly HttpServerUtilityBase _serverUtility;

    public FaceComparisonService(HttpServerUtilityBase serverUtility)
    {
        _serverUtility = serverUtility;
    }

    // 核心比对逻辑
    public void RunComparison()
    {
        var inList = GetMatchInList();
        var outList = GetMatchOutList();
        // 这里可以添加比对后的业务处理，比如结果存储、日志记录等
    }

    // 原FaceMatchInList方法迁移过来
    public List<FaceCompareModel> GetMatchInList()
    {
        string[] filePaths = null;
        DateTime foldertime = DateTime.Now;
        string folderdatelocation = foldertime.ToString("yyyy-MM-dd");
        string path = _serverUtility.MapPath("~/FolderLocation/CapImgLoaction.txt");
        string FolderLocation;
        string myString;
        
        using (StreamReader reader = System.IO.File.OpenText(path))
        {
            FolderLocation = reader.ReadToEnd();
            string location1path = _serverUtility.MapPath("~/FolderLocation/location1.txt");
            string location1;
            string location1String;
            using (StreamReader location1reader = System.IO.File.OpenText(location1path))
            {
                location1 = location1reader.ReadToEnd();
                location1String = location1.Replace("\r\n", string.Empty);
            }
            string location2path = _serverUtility.MapPath("~/FolderLocation/location2.txt");
            string location2;
            string location2String;
            using (StreamReader location2reader = System.IO.File.OpenText(location2path))
            {
                location2 = location2reader.ReadToEnd();
                location2String = location2.Replace("\r\n", string.Empty);
            }
            Rijndael128EncryptorDAO rnDAO = new Rijndael128EncryptorDAO();
            string decrypt = rnDAO.AES_decrypt(FolderLocation, location1String, location2String);
            myString = decrypt.Replace("\r\n", string.Empty);
        }
        
        string INIPAddressPath = _serverUtility.MapPath("~/FolderLocation/INCameraIPAddress.txt");
        string INCameraIPAddress;
        string INCameraIPAddressmyString;
        using (StreamReader reader = System.IO.File.OpenText(INIPAddressPath))
        {
            INCameraIPAddress = reader.ReadToEnd();
            string location1path = _serverUtility.MapPath("~/FolderLocation/location1.txt");
            string location1;
            string location1String;
            using (StreamReader location1reader = System.IO.File.OpenText(location1path))
            {
                location1 = location1reader.ReadToEnd();
                location1String = location1.Replace("\r\n", string.Empty);
            }
            string location2path = _serverUtility.MapPath("~/FolderLocation/location2.txt");
            string location2;
            string location2String;
            using (StreamReader location2reader = System.IO.File.OpenText(location2path))
            {
                location2 = location2reader.ReadToEnd();
                location2String = location2.Replace("\r\n", string.Empty);
            }
            Rijndael128EncryptorDAO rnDAO = new Rijndael128EncryptorDAO();
            string decrypt = rnDAO.AES_decrypt(INCameraIPAddress, location1String, location2String);
            INCameraIPAddressmyString = decrypt.Replace("\r\n", string.Empty);
        }
        
        try
        {
            filePaths = Directory.GetFiles(myString + "\\" + folderdatelocation + "\\" + INCameraIPAddressmyString + "\\" + "CompOk", "*_SRC.JPG*");
        }
        catch (Exception ex)
        {
            // 建议添加异常日志，方便排查问题
            // Logger.Error("读取图片路径失败", ex);
        }
        
        // 补充返回逻辑，根据实际业务返回数据
        return new List<FaceCompareModel>();
    }

    // 原FaceMatchOutList方法迁移过来
    public List<FaceCompareModel> GetMatchOutList()
    {
        // 你的业务逻辑实现
        return new List<FaceCompareModel>();
    }
}

2. 在项目启动时初始化定时任务，修改Global.asax：

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    RouteConfig.RegisterRoutes(RouteTable.Routes);

    // 初始化定时任务，比如每分钟执行一次比对
    var timer = new System.Timers.Timer(60000);
    timer.Elapsed += (sender, e) =>
    {
        var comparisonService = new FaceComparisonService(Server);
        comparisonService.RunComparison();
    };
    timer.AutoReset = true;
    timer.Start();
}

3. 这样部署后，只要IIS站点启动，后台任务就会自动运行，开机后IIS会自动拉起站点，无需手动操作。

关键注意事项 #

• 确保项目中读取的文本文件路径正确，部署后Server.MapPath指向的是IIS站点的物理路径，要保证这些文件存在且权限配置正确（给IIS应用程序池账户读取权限）。
• 如果用任务计划，要测试命令是否能正常调用接口，避免权限不足的问题。
• 建议给业务逻辑添加异常捕获和日志记录，方便后续排查问题。
