模拟键盘事件

我正在尝试将字符串值插入第三方应用程序（例如记事本）。下面是我正在使用的代码，

[DllImport("user32.dll")]
    static extern void keybd_event(byte bVk, byte bScan, uint dwFlags, UIntPtr dwExtraInfo);

public  void sim_type(string txt)
    {

        const int KEYEVENTF_EXTENDEDKEY = 0x1;
        const int KEYEVENTF_KEYUP = 0x2;
        byte[] ASCIIValues = Encoding.ASCII.GetBytes(txt);

        foreach (byte keyCode in ASCIIValues)
        {
            Console.WriteLine("Ascii Values = " + keyCode);
            keybd_event(keyCode, 0x45, KEYEVENTF_EXTENDEDKEY, (UIntPtr)0);
            keybd_event(keyCode, 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, (UIntPtr)0);
        }


    }

我给出了一条示例文本消息，例如“这是一条测试消息”。我得到了正确的 ascii 值。但在相应示例消息的目标文本框中，我得到了此输出。

t89 9 1 13:38 02/12/2010513:38 02/12/2010 -5175

有人可以帮忙解决这个问题吗？我还将 ascii 值打印在控制台中

消息：这是一条测试消息
{
Ascii 值 = 84
Ascii 值 = 104
Ascii 值 = 105
Ascii 值 = 115
Ascii 值 = 32
Ascii 值 = 105
Ascii 值 = 115
Ascii 值 = 32
Ascii 值 = 97
Ascii 值 = 32
Ascii 值 = 116
Ascii 值 = 101
Ascii 值 = 115
Ascii 值 = 116
Ascii 值 = 32
Ascii 值 = 109
Ascii 值 = 101
Ascii 值 = 115
Ascii 值 = 115
Ascii 值 = 97
Ascii 值 = 103
Ascii 值 = 101
}

帮忙谢谢，尼基尔

原文

I am trying to insert string values to a third party application say, notepad. Below is the code that I am using

[DllImport("user32.dll")]
    static extern void keybd_event(byte bVk, byte bScan, uint dwFlags, UIntPtr dwExtraInfo);

public  void sim_type(string txt)
    {

        const int KEYEVENTF_EXTENDEDKEY = 0x1;
        const int KEYEVENTF_KEYUP = 0x2;
        byte[] ASCIIValues = Encoding.ASCII.GetBytes(txt);

        foreach (byte keyCode in ASCIIValues)
        {
            Console.WriteLine("Ascii Values = " + keyCode);
            keybd_event(keyCode, 0x45, KEYEVENTF_EXTENDEDKEY, (UIntPtr)0);
            keybd_event(keyCode, 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, (UIntPtr)0);
        }


    }

I am giving a sample text message For example "This is a test Message".
I am getting the proper ascii values.
But in the target text box for the corresponding sample message I am getting this output.

t89 9 1 13:38 02/12/2010513:38 02/12/2010 -5175

Could some one help to solve this. I am also putting the ascii values printed in console

Messsage :This is a test message
{
Ascii Values = 84
Ascii Values = 104
Ascii Values = 105
Ascii Values = 115
Ascii Values = 32
Ascii Values = 105
Ascii Values = 115
Ascii Values = 32
Ascii Values = 97
Ascii Values = 32
Ascii Values = 116
Ascii Values = 101
Ascii Values = 115
Ascii Values = 116
Ascii Values = 32
Ascii Values = 109
Ascii Values = 101
Ascii Values = 115
Ascii Values = 115
Ascii Values = 97
Ascii Values = 103
Ascii Values = 101
}
