这些天，我正在使用 MS Visual Studio 2010 Professional 处理 C++/CLI (Visual C++) 项目。我有一个SRecognizer使用一些 C# 库的类。现在，它有以下代码

r = gcnew RTMotionDetector();

Thread ^detectionThread = gcnew Thread(gcnew System::Threading::ThreadStart(this,&r->start()));

该类RMotionDetector的标题如下

#pragma once
#include "MotionDetector.h"

ref class RTMotionDetector :
    public MotionDetector
{
public:
    RTMotionDetector(void);
    ~RTMotionDetector(void);
    void start();
    void pause();
    void stop();

private:
    VideoCapture *cam1;
};

当程序运行时，它给出了以下错误

1>------ Build started: Project: Automated Intruder Tracking System, Configuration: Debug Win32 ------

如您所见，错误在于我如何创建SRecognizer您已经拥有上述特定代码的线程。我对 C++/CLI 相当陌生。

这应该修复编译器错误：

Thread^ detectionThread = gcnew Thread(gcnew System::Threading::ThreadStart(r, &RTMotionDetector::start));
