求教.net compact framework 上实现双击exe文件只出一个实例的问题

[forestwind]

我的问题是如何在.net compact framework 框架下实现双击exe文件只出一个实例，在普通.net framework上实现这个没有问题，以下是代码

[MTAThread]
static void Main()
{
Process instance = RunningInstance();
if (instance == null)
{
//There isn't another instance, show our form.
Application.Run(new Form1());
}
else
{
//There is another instance of this process.
HandleRunningInstance(instance);

}

//Application.Run(new Form1());
}

public static Process RunningInstance()
{
Process current = Process.GetCurrentProcess();

Process[] processes = Process.GetProcessesByName (current.ProcessName);
// Process[] processes = Process.GetProcessById(current.Id);
//Loop through the running processes in with the same name
foreach (Process process in processes)
{
//Ignore the current process
if (process.Id != current.Id)
{
//Make sure that the process is running from the exe file.
if (Assembly.GetExecutingAssembly().Location.Replace("/", "\\") == current.MainModule.FileName)
{
//Return the other process instance.
return process;
}
}
}//foreach

}//runninginstance

可是在.net compact framework框架下没有GetProcessesByName，Assembly.GetExecutingAssembly().Location和current.MainModule这个功能，可是我又找不到替代，诚心求教大牛给予指点

 static void Main()
        {
            int iProcessNum = 0;

            foreach (Process singleProc in Process.GetProcesses())
            {
                if (singleProc.ProcessName == Process.GetCurrentProcess().ProcessName)
                {
                    iProcessNum += 1;
                }
            }
            if (iProcessNum == 2)
            {
                LitianClass.MessageBoxOK("管理系统\n\n已经在运行中……");
            }
            else if (iProcessNum > 2)
            {
                return;
            }
            else
            {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);
                Application.Run(new login());
            }
        }

这里WinForm下的，你看可不可以，手头没环境不好测试，
另外WinCE应该有FindWindow这个API吧，查找窗口类或名称固定的，
这样就能判断了

 static void Main()
        {
            bool isRun;
            System.Threading.Mutex mu = new System.Threading.Mutex(true, "OnlyRunOneInstance", out isRun);
            if (isRun)
            {

                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);
                Application.Run(new Form1());
                mu.ReleaseMutex();
            }
            else
            {
                MessageBox.Show("程序已经运行!", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
        }

回复3楼跟4楼的兄弟，你们调用的函数compact framework 里面不包括啊

[huwei001982]

和 winform 一样， 用 Mutex 啊， google 一下

搜过了，主要问题是compact framework 的 mutex 构造函数不支持三个参数，没有了第三个bool, 没法判断啊
