창 파일 이름 가져 오기가 작동하지 않습니다.

Question

나는 몇 시간 동안 인터넷 검색을하고 찾은 모든 것을 시도했지만 작동하지 않는 것 같습니다.

내 코드는 다음과 같습니다

private static long _i; 
private static readonly System.Timers.Timer Timer = new System.Timers.Timer(1000); 

[DllImport("user32.dll")] 
private static extern IntPtr GetForegroundWindow(); 

[DllImport("user32.dll")] 
private static extern int GetWindowText(IntPtr hWnd, StringBuilder text, int count); 

[DllImport("user32.dll")] 
private static extern int GetWindowModuleFileName(IntPtr hWnd, StringBuilder text, int count); 

static void Main() 
{ 
    Timer.Elapsed += Timer_Elapsed; 
    Timer.AutoReset = true; 
    Timer.Start(); 
    while (Timer.Enabled) 
     Console.ReadLine(); 
} 

static void Timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) 
{ 
    Console.WriteLine("-|- - " + _i + " - -|-"); 
    Console.WriteLine("WindowHandle: " + GetForegroundWindow()); 
    var buff = new StringBuilder(2048); 
    GetWindowModuleFileName(GetForegroundWindow(), buff, 1024); 
    Console.WriteLine("ModuleName: " + Path.GetFileName(buff.ToString())); 
    Console.WriteLine("-|- - | - -|-"); 
    _i++;  
} 

이 코드의 출력은 항상이 같은 것입니다 :

-|- - 1 - -|- 
WindowHandle: 8128962 
ModuleName: ConsoleApplication.vshost.exe 
-|- - | - -|- 

하지만 크롬 또는 피들러와 같은 다른 응용 프로그램을 대상으로하는 경우에도, 항상 출력합니다 내 실행 파일 이름 또는 파일 이름 없음. 누락 된 문제가 있습니까?

를 사용합니다. foregoundwindow에 속한 프로세스를 얻어야합니다. 이 작업을 수 있습니다

[Flags]

     uint pid; 
     GetWindowThreadProcessId(GetForegroundWindow(), out pid); 
     IntPtr proc = OpenProcess(ProcessAccessFlags.VMRead | ProcessAccessFlags.QueryInformation, true, pid); 
     var buff = new StringBuilder(2048); 
     GetModuleFileNameEx(proc, (IntPtr) 0, buff, 1024); 
     Console.WriteLine("ModuleName: " + Path.GetFileName(buff.ToString())); 
     Console.WriteLine("-|- - | - -|-"); 
     _i++; 
     CloseHandle(proc); 
    }

당신이 하나 System.Management에 대한 참조를 추가해야합니다 - 그것은 당신이 하나 추가 단계를 확인해야합니다 WMI
