Попробуйте вместо этого использовать DllImport, например:
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool SetForegroundWindow(IntPtr hWnd);
[DllImport("user32.DLL")]
public static extern IntPtr FindWindow(string lpszClass, string lpszWindow);
Определить hWnd как:
IntPtr hWnd;
В вашем задании выполните:
hWnd = theProcess.MainWindowHandle; // or use your theProcess.Handle
Кроме того, этот разрыв в операторе if не будет устанавливать окно на передний план, если оно его найдет. Вам нужно переделать этот сегмент кода в что-то вроде:
if (theprocess.ProcessName.StartsWith(name))
{
main_title = theprocess.MainWindowTitle;
hWnd = theProcess.MainWindowHandle;
}
else
hWnd = FindWindow(null, main_title);
if (hWnd != null && !hWnd.Equals(IntPtr.Zero))
{
SetForegroundWindow(hWnd);
// may want to put your break here
}
Класс окна
Win32 - это просто класс, содержащий все описанные выше DllImport, поскольку я использую их в нескольких дочерних классах Win32.
public class Window : Win32
{
public IntPtr Handle;
public Window(IntPtr handle)
{
Handle = handle;
}
public bool Visible
{
get { return IsWindowVisible(Handle); }
set
{
ShowWindow(Handle, value ? ShowWindowConsts.SW_SHOW :
ShowWindowConsts.SW_HIDE);
}
}
public void Show()
{
Visible = true;
SetForegroundWindow(Handle);
/*
try { SwitchToThisWindow(Handle, false); } // this is deprecated - may throw on new window platform someday
catch { SetForegroundWindow(Handle); } //
*/
}
public void Hide() { Visible = false; }
}
Класс ShowWindowConsts
namespace Win32
{
public class ShowWindowConsts
{
// Reference: http://msdn.microsoft.com/en-us/library/ms633548(VS.85).aspx
/// <summary>
/// Minimizes a window, even if the thread that owns the window is not responding.
/// This flag should only be used when minimizing windows from a different thread.
/// </summary>
public const int SW_FORCEMINIMIZE = 11;
/// <summary>
/// Hides the window and activates another window.
/// </summary>
public const int SW_HIDE = 0;
/// <summary>
/// Maximizes the specified window.
/// </summary>
public const int SW_MAXIMIZE = 3;
/// <summary>
/// Minimizes the specified window and activates the next top-level window in the Z order.
/// </summary>
public const int SW_MINIMIZE = 6;
/// <summary>
/// Activates and displays the window.
/// If the window is minimized or maximized, the system restores it to
/// its original size and position.
/// An application should specify this flag when restoring a minimized window.
/// </summary>
public const int SW_RESTORE = 9;
/// <summary>

/// </summary>
public const int SW_SHOW = 5;
/// <summary>

/// </summary>
public const int SW_SHOWDEFAULT = 10;
/// <summary>
/// Activates the window and displays it as a maximized window.
/// </summary>
public const int SW_SHOWMAXIMIZED = 3;
/// <summary>
/// Activates the window and displays it as a minimized window.
/// </summary>
public const int SW_SHOWMINIMIZED = 2;
/// <summary>
/// Displays the window as a minimized window.
/// This value is similar to public const long SW_SHOWMINIMIZED,

/// </summary>
public const int SW_SHOWMINNOACTIVE = 7;
/// <summary>
/// Displays the window in its current size and position.
/// This value is similar to public const long SW_SHOW, except that the window is not activated.
/// </summary>
public const int SW_SHOWNA = 8;
/// <summary>
/// Displays a window in its most recent size and position.
/// This value is similar to public const long SW_SHOWNORMAL,
/// except that the window is not activated.
/// </summary>
public const int SW_SHOWNOACTIVATE = 4;
public const int SW_SHOWNORMAL = 1;
}
}
Таким образом, ваш код станет:
if (theprocess.ProcessName.StartsWith(name))
{
main_title = theprocess.MainWindowTitle;
hWnd = theProcess.MainWindowHandle;
}
else
hWnd = FindWindow(null, main_title);
if (hWnd != null && !hWnd.Equals(IntPtr.Zero))
{
new Window(hWnd).Show();
}
