检查特定的exe文件是否正在运行

Question

我想知道如果程序正在运行,我可以检查特定位置的程序.例如,c:\ loc1\test.exe和c:\ loc2\test.exe中的test.exe有两个位置.我只想知道c:\ loc1\test.exe是否正在运行,而不是所有的test.exe实例.

Answer 1

bool isRunning = Process.GetProcessesByName("test")
                .FirstOrDefault(p => p.MainModule.FileName.StartsWith(@"c:\loc1")) != default(Process);

Answer 2

这是我改进的功能:

private bool ProgramIsRunning(string FullPath)
{
    string FilePath =  Path.GetDirectoryName(FullPath);
    string FileName = Path.GetFileNameWithoutExtension(FullPath).ToLower();
    bool isRunning = false;

    Process[] pList = Process.GetProcessesByName(FileName);

    foreach (Process p in pList) {
        if (p.MainModule.FileName.StartsWith(FilePath, StringComparison.InvariantCultureIgnoreCase))
        {
            isRunning = true;
            break;
        }
    }

    return isRunning;
}

并将其用作:

ProgramIsRunning(@"c:\loc1\test.exe");

尝试这个...我用它来确定启动时是否已经运行了另一个进程,其名称与我正在尝试启动的exe相同,然后只需将其中一个放到前台,(并且要聚焦)如果已经正在运行...您可以对其进行修改以获取进程名称并测试该特定名称...这将告诉您是否存在使用某个名称运行的进程,而不是从该进程加载的位置...

如果有一个使用指定名称运行的进程,那么如果该进程有一个公开的可访问方法返回它的加载位置,你可以在正在运行的进程上调用该方法,否则,我不知道..

但出于好奇,你为什么要关心,除非他们不同？如果它们在某种程度上有所不同,则使用该差异(无论它是什么)来检测哪些已加载.但是,如果它们是相同的,那么使用哪个磁盘映像加载它又有什么关系呢？

    [DllImport("user32.dll")]
    private static extern bool SetForegroundWindow(IntPtr hWnd);
    [DllImport("user32.dll")]
    private static extern bool ShowWindowAsync(IntPtr hWnd, int nCmdShow);

 private static bool IsAlreadyRunning()
    {
        // get all processes by Current Process name
        Process[] processes = 
            Process.GetProcessesByName(
                Process.GetCurrentProcess().ProcessName);

        // if there is more than one process...
        if (processes.Length > 1) 
        {
            // if other process id is OUR process ID...
            // then the other process is at index 1
            // otherwise other process is at index 0
            int n = (processes[0].Id == Process.GetCurrentProcess().Id) ? 1 : 0;

            // get the window handle
            IntPtr hWnd = processes[n].MainWindowHandle;

            // if iconic, we need to restore the window
            if (IsIconic(hWnd)) ShowWindowAsync(hWnd, SW_RESTORE);

            // Bring it to the foreground
            SetForegroundWindow(hWnd);
            return true;
        }
        return false;
    }

您应该迭代所有现有进程，然后检查其 MainModule 属性以获取您要查找的文件名。像这样的东西

using System.Diagnostics;
using System.IO;

//...

string fileNameToFilter = Path.GetFullPath("c:\\loc1\\test.exe");

foreach (Process p in Process.GetProcesses())
{
   string fileName = Path.GetFullPath(p.MainModule.FileName);

   //cehck for equality (case insensitive)
   if (string.Compare(fileNameToFilter, fileName, true) == 0)
   {
      //matching...
   }
}
