如何将Form键转换为Wpf键? [英] How to convert Form keys to Wpf Keys?

问题描述

您好，我在wpf中使用了密钥挂钩机制( http://www.codeproject.com /KB/cs/globalhook.aspx )
但是在上面的lind中，它们使用表单键.但我想将其转换为Wpf.这里的问题是Forms键包含0到255和一些特殊的Enum成员，但在System.Windows.Input.Key中仅包含0-171 Enum me成员.如果我按171枚举键上方，它将通过异常.如何将表单密钥转换为Wpf密钥?或任何一个人都可以在以下链接中给我提供UserActivityHook的Wpf版本

I'm Using Key Hooking Mechanism In wpf(http://www.codeproject.com/KB/cs/globalhook.aspx)
But in the above lind they use forms keys. But i want to convert it to Wpf.

推荐答案

不幸的是，这里没有直接转换，并且有两种类型的密钥.但是，解析它们并找出映射是否存在非常简单.如下所述，如果不存在具有相同名称的成员，则只需为该键放置特殊的大写代码，而不是尝试使用Parse()操作即可.

Sadly there's no direct cast there and there ARE two types of Key(s).  However, it's pretty simple to parse them and figure out if a mapping exists.  As noted below, if a member with the same identical name doesnt exist, it's simply a matter of placing special casing code  for that key instead of trying the Parse() operation.

public 静态 System.Windows.Input.KeyWinformsToWPFKey(System.Windows.Forms.KeysinputKey)

{

//如果存在需要的键，则不需要特殊映射，请在这里放置特殊情况逻辑... 尝试

.{

返回 (System.Windows.Input .Key)Enum.Parse( typeof (System.Windows.Input.Key)，inputKey. ToString());

捕获

.{

//没有直接映射... 返回 System.Windows.Input.Key.None;

public static System.Windows.Input.Key WinformsToWPFKey(System.Windows.Forms.Keys inputKey)

{

// Put special case logic here if there's a key you need but doesn't map...

try

{

return (System.Windows.Input.Key)Enum.Parse(typeof(System.Windows.Input.Key), inputKey.ToString());

}

catch

{

// There wasn't a direct mapping...

return System.Windows.Input.Key.None;

}

}
