我们在软件中经常用到快捷键，这里整理备份一下。
首先我们要定义可以作为快捷键的按键，以下是整理的 一些，自己可以根据情况来修改
代码语言：javascript复制 public static Dictionary<int, string> HotKeys = new Dictionary<int, string>()
{
{48,"0"},
{49,"1"},
{50,"2"},
{51,"3"},
{52,"4"},
{53,"5"},
{54,"6"},
{55,"7"},
{56,"8"},
{57,"9"},
{65,"A"},
{66,"B"},
{67,"C"},
{68,"D"},
{69,"E"},
{70,"F"},
{71,"G"},
{72,"H"},
{73,"I"},
{74,"J"},
{75,"K"},
{76,"L"},
{77,"M"},
{78,"N"},
{79,"O"},
{80,"P"},
{81,"Q"},
{82,"R"},
{83,"S"},
{84,"T"},
{85,"U"},
{86,"V"},
{87,"W"},
{88,"X"},
{89,"Y"},
{90,"Z"},
{112,"F1"},
{113,"F2"},
{114,"F3"},
{115,"F4"},
{116,"F5"},
{117,"F6"},
{118,"F7"},
{119,"F8"},
{120,"F9"},
{121,"F10"},
{122,"F11"},
{123,"F12"},
{33,"PageUp"},
{34,"PageDown"},
{35,"End"},
{36,"Home"},
{37,"←"},
{38,"↑"},
{39,"→"},
{40,"↓"},
{45,"Insert"},
{46,"Delete"},
{186,";"},
{187,"="},
{188,","},
{189,"-"},
{190,"."},
{191,"/"},
{192,"`"},
{219,"["},
{220,"\"},
{221,"]"}
};然后弄个数据表存一下定义功能对应的快捷键，表结构如下
代码语言：javascript复制CREATE TABLE [dbo].[HotKey](
[ID] [int] IDENTITY(1,1) NOT NULL,
[FrmName] [nvarchar](50) NULL,
[Sort] [int] NULL,
[ActionName] [nvarchar](50) NULL,
[ActionKey] [nvarchar](50) NULL,
[KeyValue] [nvarchar](50) NULL
) ON [PRIMARY]
GO
EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'界面' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'HotKey', @level2type=N'COLUMN',@level2name=N'FrmName'
GO
EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'顺序' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'HotKey', @level2type=N'COLUMN',@level2name=N'Sort'
GO
EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'功能名称' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'HotKey', @level2type=N'COLUMN',@level2name=N'ActionName'
GO
EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'功能编码' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'HotKey', @level2type=N'COLUMN',@level2name=N'ActionKey'
GO
EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'热键' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'HotKey', @level2type=N'COLUMN',@level2name=N'KeyValue'
GO系统启动的时候缓存一下设置的快捷键
代码语言：javascript复制public static List<HotKey> HotKeySetting { get; set; }基类窗体里面写窗体的
写KeyUP 和KeyDown事件
代码语言：javascript复制 bool m_blnCtrl = false;
bool m_blnAlt = false;
bool m_blnShift = false;
[Description("定义的热键列表"), Category("自定义")]
public Dictionary<int, string> HotKeys { get; set; }
//如果事件返回true则表示已经找到了快捷键事件，则不再向下传递
public delegate bool HotKeyEventHandler(string strHotKey);
/// <summary>
/// 热键事件
/// </summary>
[Description("热键事件"), Category("自定义")]
public event HotKeyEventHandler HotKeyDown;
protected void FrmBase_KeyUp(object sender, KeyEventArgs e)
{
if (HotKeyDown != null && HotKeys != null)
{
if (e.KeyCode == Keys.Control || e.KeyCode == Keys.ControlKey)
m_blnCtrl = false;
if (e.KeyCode == Keys.Alt || e.KeyCode == Keys.Menu)
m_blnAlt = false;
if (e.KeyCode == Keys.Shift || e.KeyCode == Keys.ShiftKey)
m_blnShift = false;
}
}
protected void FrmBase_KeyDown(object sender, KeyEventArgs e)
{
if (HotKeyDown != null && HotKeys != null)
{
if (e.KeyCode == Keys.Control || e.KeyCode == Keys.ControlKey)
m_blnCtrl = true;
if (e.KeyCode == Keys.Alt || e.KeyCode == Keys.Menu)
m_blnAlt = true;
if (e.KeyCode == Keys.Shift || e.KeyCode == Keys.ShiftKey)
m_blnShift = true;
if (HotKeys.ContainsKey(e.KeyValue))
{
string strKey = string.Empty;
if (m_blnCtrl)
{
strKey = "Ctrl ";
}
if (m_blnAlt)
{
strKey = "Alt ";
}
if (m_blnShift)
{
strKey = "Shift ";
}
strKey = HotKeys[e.KeyValue];
if (HotKeyDown(strKey))
{
e.Handled = true;
e.SuppressKeyPress = true;
}
}
}
} 你会注意到keyup和kedown事件的修饰符是protected，为什么要用protected呢？是因为窗体的一些输入控件的按键事件是不会传递到窗体的，比如textbox这些，所有需要手动指定一下
子窗体中注册事件就可以了，如果你没有用基类窗体，那么直接写在一起就可以了
代码语言：javascript复制this.HotKeys = HotKeys;
this.HotKeyDown = FrmMain_HotKeyDown;
//将输入框的2个事件指向窗体的2个事件
this.txtSearch.KeyDown = this.FrmBase_KeyDown;
this.txtSearch.KeyUp = this.FrmBase_KeyUp;
/// <summary>
/// 热键按下事件
/// </summary>
/// <param name="strHotKey">热键值</param>
/// <returns>当返回true则表示不再向下传递按键事件，通常当匹配到热键操作后返回true</returns>
bool FrmMain_HotKeyDown(string strHotKey)
{
Console.WriteLine(strHotKey);
string strHotAction = GetHotKeyAction("FrmMain", strHotKey);
if (string.IsNullOrEmpty(strHotAction))
return false;
else
{
//这里根据返回的功能名称做操作就可以了
return true;
}
}
public static string GetHotKeyAction(string strFrom, string strHotKey)
{
var entity = HotKeySetting.Find(p => p.FrmName.ToLower() == strFrom.ToLower() && p.KeyValue.ToStringExt().ToLower() == strHotKey.ToLower());
if (entity != null)
return entity.ActionKey;
else
return string.Empty;
}这样就可以了
