Check if a specific exe file is running

Question

I want to know how i can check a program in a specific location if it is running. For example there are two locations for test.exe in c:\\loc1\\test.exe and c:\\loc2\\test.e

Something like this. GetMainModuleFileName helps to access x64 process from x86.

  [DllImport("kernel32.dll")]
  public static extern bool QueryFullProcessImageName(IntPtr hprocess, int dwFlags, StringBuilder lpExeName, out int size);

  private bool CheckRunningProcess(string processName, string path) {

  Process[] processes = Process.GetProcessesByName(processName);
  foreach(Process p in processes) {
    var name = GetMainModuleFileName(p);
    if (name == null)
      continue;
    if (string.Equals(name, path, StringComparison.InvariantCultureIgnoreCase)) {
      return true;
    }
  }
  return false;
}

// Get x64 process module name from x86 process
private static string GetMainModuleFileName(Process process, int buffer = 1024) {

  var fileNameBuilder = new StringBuilder(buffer);
  int bufferLength = fileNameBuilder.Capacity + 1;
  return QueryFullProcessImageName(process.Handle, 0, fileNameBuilder, out bufferLength) ?
      fileNameBuilder.ToString() :
      null;
}
