C#窗体如何通过keybd_event()函数模拟键盘按键（组合键）产生事件
如何模拟键盘按键触发产生的事件，比如模拟按下Alt + F4 关闭当前程序，Ctrl+Shift 切换输入法等
可以通过win32api 键盘事件 keybd_event() 来实现
1、定义键盘按键对应得键码
#region bVk参数 常量定义
public const byte vbKeyLButton = 0x1; // 鼠标左键
public const byte vbKeyRButton = 0x2; // 鼠标右键
public const byte vbKeyCancel = 0x3; // CANCEL 键
public const byte vbKeyMButton = 0x4; // 鼠标中键
public const byte vbKeyBack = 0x8; // BACKSPACE 键
public const byte vbKeyTab = 0x9; // TAB 键
public const byte vbKeyClear = 0xC; // CLEAR 键
public const byte vbKeyReturn = 0xD; // ENTER 键
public const byte vbKeyShift = 0x10; // SHIFT 键
public const byte vbKeyControl = 0x11; // CTRL 键
public const byte vbKeyAlt = ; // Alt 键 (键码18)
public const byte vbKeyMenu = 0x12; // MENU 键
public const byte vbKeyPause = 0x13; // PAUSE 键
public const byte vbKeyCapital = 0x14; // CAPS LOCK 键
public const byte vbKeyEscape = 0x1B; // ESC 键
public const byte vbKeySpace = 0x20; // SPACEBAR 键
public const byte vbKeyPageUp = 0x21; // PAGE UP 键
public const byte vbKeyEnd = 0x23; // End 键
public const byte vbKeyHome = 0x24; // HOME 键
public const byte vbKeyLeft = 0x25; // LEFT ARROW 键
public const byte vbKeyUp = 0x26; // UP ARROW 键
public const byte vbKeyRight = 0x27; // RIGHT ARROW 键
public const byte vbKeyDown = 0x28; // DOWN ARROW 键
public const byte vbKeySelect = 0x29; // Select 键
public const byte vbKeyPrint = 0x2A; // PRINT SCREEN 键
public const byte vbKeyExecute = 0x2B; // EXECUTE 键
public const byte vbKeySnapshot = 0x2C; // SNAPSHOT 键
public const byte vbKeyDelete = 0x2E; // Delete 键
public const byte vbKeyHelp = 0x2F; // HELP 键

//常用键 字母键A到Z

public const byte vbKeyZ = ;
//数字键盘0到9
public const byte vbKey0 = ; // 0 键
public const byte vbKey1 = ; // 1 键
public const byte vbKey2 = ; // 2 键
public const byte vbKey3 = ; // 3 键
public const byte vbKey4 = ; // 4 键
public const byte vbKey5 = ; // 5 键
public const byte vbKey6 = ; // 6 键
public const byte vbKey7 = ; // 7 键
public const byte vbKey8 = ; // 8 键
public const byte vbKey9 = ; // 9 键
public const byte vbKeyNumpad0 = 0x60 ; //0 键
public const byte vbKeyNumpad1 = 0x61 ; //1 键

public const byte vbKeyNumpad7 = 0x67 ; //7 键
public const byte vbKeyNumpad8 = 0x68 ; //8 键
public const byte vbKeyNumpad9 = 0x69 ; //9 键
public const byte vbKeyMultiply = 0x6A ; // MULTIPLICATIONSIGN(*)键
public const byte vbKeyAdd = 0x6B ; // PLUS SIGN(+) 键
public const byte vbKeySeparator = 0x6C ; // ENTER 键
public const byte vbKeySubtract = 0x6D ; // MINUS SIGN(-) 键
public const byte vbKeyDecimal = 0x6E ; // DECIMAL POINT(.) 键
public const byte vbKeyDivide = 0x6F ; // DIVISION SIGN(/) 键
//F1到F12按键
public const byte vbKeyF1 = 0x70 ; //F1 键
public const byte vbKeyF2 = 0x71 ; //F2 键

public const byte vbKeyF10 = 0x79 ; //F10 键
public const byte vbKeyF11 = 0x7A ; //F11 键
public const byte vbKeyF12 = 0x7B ; //F12 键
#endregion
2、引用win32api键盘函数
#region 引用win32api方法
/// <summary>

/// <param name="bVk" >按键的虚拟键值</param>
/// <param name= "bScan" >扫描码，一般不用设置，用0代替就行</param>

/// <param name= "dwExtraInfo">一般设置为0</param>
[DllImport("user32.dll")]
public static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);
#endregion
3、使用例子
