新程序覆盖原来正在运行的程序并重新启动的问题

Question

由于原程序在运行，所以想先把原程序进程kill
   Process currentProcess = Process.GetCurrentProcess();
               Process[] processes = Process.GetProcessesByName(currentProcess.ProcessName);
                foreach (Process process in processes)
                {
                    if (process.Id != currentProcess.Id)
                    {
                        process.Kill();
                        process.WaitForExit();
                    }
                }

                System.IO.File.Copy(currentFile, targetFile, true);
                              
                System.Diagnostics.Process.Start(targetFile);

 
                this.Close();
                Application.Exit();

可是在执行替换时还是提示程序正在运行，无法替换；另外File.Copy后面的语句会等拷贝完成后再执行么？

Answer 1

你好！

KILL 后不一定马上关掉，你可以等一些时间再执行拷贝。

 Process currentProcess = Process.GetCurrentProcess();
               Process[] processes = Process.GetProcessesByName(currentProcess.ProcessName);
                foreach (Process process in processes)
                {
                    if (process.Id != currentProcess.Id)
                    {
                        process.Kill();
                        process.WaitForExit();
                    }
                }

Thread.Sleep(500);

                System.IO.File.Copy(currentFile, targetFile, true);
                               
                System.Diagnostics.Process.Start(targetFile);

 
                this.Close();
                Application.Exit();

Thread.Sleep(500);
可是这个时间如何控制呢，如果500ms也没关掉呢，process.WaitForExit();不起作用？有没有判断结束的方法啊？

另外File.Copy后面的语句会等拷贝完成后再执行么？

Answer 3

你这样写,你的方法并没有把当前线程杀死
       System.Diagnostics.Process[] myProcesses = System.Diagnostics.Process.GetProcesses();

            Process currentProcess = Process.GetCurrentProcess();
            foreach (System.Diagnostics.Process myProcess in myProcesses)
            {
                if (currentProcess.ProcessName == myProcess.ProcessName)
                    myProcess.Kill();
            }

看清问题先

Answer 5

Process currentProcess = Process.GetCurrentProcess();

Process[] processes = Process.GetProcessesByName(currentProcess.ProcessName);

foreach (Process process in processes)

{

    if (process.Id != currentProcess.Id)

        process.Kill();

}

Thread.Sleep(20);

int tryCount = 0;

// 失败了再尝试，最多尝试 10 次            

while (true)

{

    try

    {

        System.IO.File.Copy(currentFile, targetFile, true);

        System.Diagnostics.Process.Start(targetFile);

        break;

    }

    catch

    {

        Thread.Sleep(20);

    }

    tryCount++;

    if (tryCount > 10) // 最多尝试 10 次

        throw new Exception("....");

}

Process currentProcess = Process.GetCurrentProcess();
               Process[] processes = Process.GetProcessesByName(currentProcess.ProcessName);
                foreach (Process process in processes)
                {
                    if (process.Id != currentProcess.Id)
                    {
                        process.Kill();
                        while(!process.WaitForExit(60000))
{
continue;

}
System.IO.File.Copy(currentFile, targetFile, true);
                              
                System.Diagnostics.Process.Start(targetFile);
                        
                    }
                }

                 
                this.Close();
                Application.Exit();

或者用单独的线程去kill进程 用锁来保证进程被kill了

Answer 7

你好！
     我认为这里不是进程没有结束的问题，除了当前进程外，同名的进程应该都结束了，你可以打开任务管理器查看一下！
     所以，这里可能还有其他进程使用相关文件，也许就是你的当前进程，或者你也可以用ProcessMonitor工具来查看一下！
