获取窗口文件名不起作用

我已经用谷歌搜索了几个小时并尝试了我找到的所有内容,但它似乎不起作用。
我的代码是:
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++;
}
此代码的输出始终如下所示:
-|- - 1 - -|-
WindowHandle: 8128962
ModuleName: ConsoleApplication.vshost.exe
-|- - | - -|-
但是,即使我针对另一个应用程序(如Chrome或Fiddler),它也总是打印出我的可执行文件名或根本没有文件名。我可能遗漏了什么问题吗?
你必须多走一步。您需要获取属于前瞻窗口的进程。这可能有效:
[Flags]
enum ProcessAccessFlags : uint
{
All = 0x001F0FFF,
Terminate = 0x00000001,
CreateThread = 0x00000002,
VMOperation = 0x00000008,
VMRead = 0x00000010,
VMWrite = 0x00000020,
DupHandle = 0x00000040,
SetInformation = 0x00000200,
QueryInformation = 0x00000400,
Synchronize = 0x00100000
}
[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);
[DllImport("user32.dll")]
private static extern IntPtr GetTopWindow(IntPtr hWnd);
[DllImport("user32.dll")]
private static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint pid);
[DllImport("kernel32.dll")]
static extern IntPtr OpenProcess(ProcessAccessFlags dwDesiredAccess, [MarshalAs(UnmanagedType.Bool)] bool bInheritHandle, uint dwProcessId);
[DllImport("psapi.dll")]
static extern uint GetModuleFileNameEx(IntPtr hProcess, IntPtr hModule, [Out] StringBuilder lpBaseName, [In] [MarshalAs(UnmanagedType.U4)] int nSize);
[DllImport("kernel32.dll", SetLastError=true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool CloseHandle(IntPtr hObject);
static void Timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
Console.WriteLine("-|- - " + _i + " - -|-");
Console.WriteLine("WindowHandle: " + GetForegroundWindow());
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);
}
这基本上是这个 C 答案的 C# 实现
您必须为此添加对 System.Management 的引用 - 它使用 WMI
