我正在使用TestApiKeyboard.Type项目中的方法在文本框中输入字符串。

    /// <summary>
    /// Types the specified text.
    /// </summary>
    /// <remarks>
    /// Note that a combination of a combination of Key.Shift or Key.Capital and a Unicode point above 0xFE
    /// is not considered valid and will not result in the Unicode point being types without 
    /// applying of the modifier key.
    /// </remarks>
    /// <param name="text">The text to type.</param>
    public static void Type(string text)
    {
        foreach (char c in text)
        {
            // If code point is bigger than 8 bits, we are going for Unicode approach by setting wVk to 0.
            if (c > 0xFE)
            {
                SendKeyboardKey(c, true, false, true);
                SendKeyboardKey(c, false, false, true);
            }
            else
            {
                // We get the vKey value for the character via a Win32 API. We then use bit masks to pull the
                // upper and lower bytes to get the shift state and key information. We then use WPF KeyInterop
                // to go from the vKey key info into a System.Windows.Input.Key data structure. This work is
                // necessary because Key doesn't distinguish between upper and lower case, so we have to wrap
                // the key type inside a shift press/release if necessary.
                int vKeyValue = NativeMethods.VkKeyScan(c);
                bool keyIsShifted = (vKeyValue & NativeMethods.VKeyShiftMask) == NativeMethods.VKeyShiftMask;
                Key key = (Key)(vKeyValue & NativeMethods.VKeyCharMask);

                if (keyIsShifted)
                {
                    Type(key, new Key[] { Key.Shift });
                }
                else
                {
                    Type(key);
                }
            }
        }
    }

    private static void SendKeyboardKey(ushort key, bool isKeyDown, bool isExtended, bool isUnicode)
    {
        var input = new NativeMethods.INPUT();
        input.Type = NativeMethods.INPUT_KEYBOARD;
        if (!isKeyDown)
        {
            input.Data.Keyboard.dwFlags |= NativeMethods.KEYEVENTF_KEYUP;
        }

        if (isUnicode)
        {
            input.Data.Keyboard.dwFlags |= NativeMethods.KEYEVENTF_UNICODE;
            input.Data.Keyboard.wScan = key;
            input.Data.Keyboard.wVk = 0;
        }
        else
        {
            input.Data.Keyboard.wScan = 0;
            input.Data.Keyboard.wVk = key;
        }

        if (isExtended)
        {
            input.Data.Keyboard.dwFlags |= NativeMethods.KEYEVENTF_EXTENDEDKEY;
        }

        input.Data.Keyboard.time = 0;
        input.Data.Keyboard.dwExtraInfo = IntPtr.Zero;

        NativeMethods.SendInput(1, new NativeMethods.INPUT[] { input }, Marshal.SizeOf(input));
        Thread.Sleep(100);
    }

它可以工作，但它输入文本相当慢。我想提高速度。理想情况下，它应该立即设置文本（考虑将文本粘贴到文本字段中）。

有没有一种简单的方法可以在 C# 中实现它（一次将文本字段的文本设置为某个字符串）？

找到了答案：

    private void setText(AutomationElement aEditableTextField, string aText)
    {
        ValuePattern pattern = aEditableTextField.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;

        if (pattern != null)
        {
            pattern.SetValue(aText);
        }
    }
