如何将string发送到包括Microsoft Word在内的其他应用程序

检查以下是否有效; 你只需要调用SendString 。 这应该适用于任何可以接收其窗口当前处于活动状态的应用程序。

除第一种方法以外的所有代码均由pinvoke.net提供 。

 /// <summary> /// Synthesizes keystrokes corresponding to the specified Unicode string, /// sending them to the currently active window. /// </summary> /// <param name="s">The string to send.</param> public static void SendString(string s) { // Construct list of inputs in order to send them through a single SendInput call at the end. List<INPUT> inputs = new List<INPUT>(); // Loop through each Unicode character in the string. foreach (char c in s) { // First send a key down, then a key up. foreach (bool keyUp in new bool[] { false, true }) { // INPUT is a multi-purpose structure which can be used // for synthesizing keystrokes, mouse motions, and button clicks. INPUT input = new INPUT { // Need a keyboard event. type = INPUT_KEYBOARD, u = new InputUnion { // KEYBDINPUT will contain all the information for a single keyboard event // (more precisely, for a single key-down or key-up). ki = new KEYBDINPUT { // Virtual-key code must be 0 since we are sending Unicode characters. wVk = 0, // The Unicode character to be sent. wScan = c, // Indicate that we are sending a Unicode character. // Also indicate key-up on the second iteration. dwFlags = KEYEVENTF_UNICODE | (keyUp ? KEYEVENTF_KEYUP : 0), dwExtraInfo = GetMessageExtraInfo(), } } }; // Add to the list (to be sent later). inputs.Add(input); } } // Send all inputs together using a Windows API call. SendInput((uint)inputs.Count, inputs.ToArray(), Marshal.SizeOf(typeof(INPUT))); } const int INPUT_MOUSE = 0; const int INPUT_KEYBOARD = 1; const int INPUT_HARDWARE = 2; const uint KEYEVENTF_EXTENDEDKEY = 0x0001; const uint KEYEVENTF_KEYUP = 0x0002; const uint KEYEVENTF_UNICODE = 0x0004; const uint KEYEVENTF_SCANCODE = 0x0008; const uint XBUTTON1 = 0x0001; const uint XBUTTON2 = 0x0002; const uint MOUSEEVENTF_MOVE = 0x0001; const uint MOUSEEVENTF_LEFTDOWN = 0x0002; const uint MOUSEEVENTF_LEFTUP = 0x0004; const uint MOUSEEVENTF_RIGHTDOWN = 0x0008; const uint MOUSEEVENTF_RIGHTUP = 0x0010; const uint MOUSEEVENTF_MIDDLEDOWN = 0x0020; const uint MOUSEEVENTF_MIDDLEUP = 0x0040; const uint MOUSEEVENTF_XDOWN = 0x0080; const uint MOUSEEVENTF_XUP = 0x0100; const uint MOUSEEVENTF_WHEEL = 0x0800; const uint MOUSEEVENTF_VIRTUALDESK = 0x4000; const uint MOUSEEVENTF_ABSOLUTE = 0x8000; struct INPUT { public int type; public InputUnion u; } [StructLayout(LayoutKind.Explicit)] struct InputUnion { [FieldOffset(0)] public MOUSEINPUT mi; [FieldOffset(0)] public KEYBDINPUT ki; [FieldOffset(0)] public HARDWAREINPUT hi; } [StructLayout(LayoutKind.Sequential)] struct MOUSEINPUT { public int dx; public int dy; public uint mouseData; public uint dwFlags; public uint time; public IntPtr dwExtraInfo; } [StructLayout(LayoutKind.Sequential)] struct KEYBDINPUT { /*Virtual Key code. Must be from 1-254. If the dwFlags member specifies KEYEVENTF_UNICODE, wVk must be 0.*/ public ushort wVk; /*A hardware scan code for the key. If dwFlags specifies KEYEVENTF_UNICODE, wScan specifies a Unicode character which is to be sent to the foreground application.*/ public ushort wScan; /*Specifies various aspects of a keystroke. See the KEYEVENTF_ constants for more information.*/ public uint dwFlags; /*The time stamp for the event, in milliseconds. If this parameter is zero, the system will provide its own time stamp.*/ public uint time; /*An additional value associated with the keystroke. Use the GetMessageExtraInfo function to obtain this information.*/ public IntPtr dwExtraInfo; } [StructLayout(LayoutKind.Sequential)] struct HARDWAREINPUT { public uint uMsg; public ushort wParamL; public ushort wParamH; } [DllImport("user32.dll")] static extern IntPtr GetMessageExtraInfo(); [DllImport("user32.dll", SetLastError = true)] static extern uint SendInput(uint nInputs, INPUT[] pInputs, int cbSize); 

Word不使用响应WM_TEXT的标准编辑控件。 要将文本SendInput Word中，您可以使用SendInput来伪造输入或COM自动化或UI自动化 。

最后这些选项，UI自动化，将是我的选择，是MS打算今天这样做的方式。
