Question

(using WPF) i try to detect when Ctrl + Enter gets hit. so i tried this code:

if (e.Key == Key.Return && (e.Key == Key.LeftCtrl || e.Key == Key.RightCtrl))
 {
   //Do Something            
 }

Obviously this is not correct, as it does not work. Could anyone help me out, explaining what the right way should be ?

thanx

Answer 1

缩略语同一情况下,其价值不能超过一种。

您需要处理使用<代码>KeyEventArgs的其中一个事件,其中你发现诸如<代码>Control和Modifiers等有助于检测组合的特性。

The KeyPress activity, which used KeyPressEventArgs, only don t have sufficient information.

Drat, 您说,妇女论坛 did你。参看<代码>e.Key板Device.Modifiers。

Answer 2

I think you need a SpecialKey Handler. I googled a bit a found a solution here.

根据上述链接的代码,可以解决你的问题:

  void SpecialKeyHandler(object sender, KeyEventArgs e)
{
    // Ctrl + N
    if ((Keyboard.Modifiers == ModifierKeys.Control) && (e.Key == Key.N))
    {
        MessageBox.Show("New");
    }

    // Ctrl + O
    if ((Keyboard.Modifiers == ModifierKeys.Control) && (e.Key == Key.O))
    {
        MessageBox.Show("Open");
    }

    // Ctrl + S
    if ((Keyboard.Modifiers == ModifierKeys.Control) && (e.Key == Key.S))
    {
        MessageBox.Show("Save");
    }

    // Ctrl + Alt + I
    if ((Keyboard.Modifiers == (ModifierKeys.Alt | ModifierKeys.Control)) && (e.Key == Key.I))
    {
        MessageBox.Show("Ctrl + Alt + I");
    }
}

Answer 3

if (e.Modifiers == Keys.Control && e.KeyCode == Keys.Enter)

Answer 4

   if (e.KeyChar == 10)
            {
             ///Code
            }

或

 if ((Char)e.KeyChar ==  
 )
            {
             ///Code
            }
