这是可能的,但只能通过 pinvoke,不幸的是这需要大约 70 行代码:
[StructLayout(LayoutKind.Sequential)]
struct STARTUPINFO
{
public Int32 cb;
public string lpReserved;
public string lpDesktop;
public string lpTitle;
public Int32 dwX;
public Int32 dwY;
public Int32 dwXSize;
public Int32 dwYSize;
public Int32 dwXCountChars;
public Int32 dwYCountChars;
public Int32 dwFillAttribute;
public Int32 dwFlags;
public Int16 wShowWindow;
public Int16 cbReserved2;
public IntPtr lpReserved2;
public IntPtr hStdInput;
public IntPtr hStdOutput;
public IntPtr hStdError;
}
[StructLayout(LayoutKind.Sequential)]
internal struct PROCESS_INFORMATION
{
public IntPtr hProcess;
public IntPtr hThread;
public int dwProcessId;
public int dwThreadId;
}
[DllImport("kernel32.dll")]
static extern bool CreateProcess(
string lpApplicationName,
string lpCommandLine,
IntPtr lpProcessAttributes,
IntPtr lpThreadAttributes,
bool bInheritHandles,
uint dwCreationFlags,
IntPtr lpEnvironment,
string lpCurrentDirectory,
[In] ref STARTUPINFO lpStartupInfo,
out PROCESS_INFORMATION lpProcessInformation
);
[DllImport("kernel32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool CloseHandle(IntPtr hObject);
const int STARTF_USESHOWWINDOW = 1;
const int SW_SHOWNOACTIVATE = 4;
const int SW_SHOWMINNOACTIVE = 7;
public static void StartProcessNoActivate(string cmdLine)
{
STARTUPINFO si = new STARTUPINFO();
si.cb = Marshal.SizeOf(si);
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_SHOWMINNOACTIVE;
PROCESS_INFORMATION pi = new PROCESS_INFORMATION();
CreateProcess(null, cmdLine, IntPtr.Zero, IntPtr.Zero, true,
0, IntPtr.Zero, null, ref si, out pi);
CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);
}
设置si.wShowWindow
为SW_SHOWNOACTIVATE
正常显示窗口但不窃取焦点,并SW_SHOWMINNOACTIVE
最小化启动应用程序,再次不窃取焦点。
