我想将GotFocus-Event添加到我的WPF-Aplication中的每个Textbox中,因为它适用于Touch Devices,每次使用TextBox时OSK都应该打开.我遇到了将事件添加到TextBoxes的过程的问题.应用程序已经构建了pc(我正在使用interhsip,我的目标是将这个应用程序带到Windows 8触摸设备).这是链接,我得到了我的灵感:添加/删除处理程序到文本框

这是我的解决方案:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    foreach (Control tb in this.Controls)
    {
        if (tb is TextBox)
        {
            TextBox tb1 = (TextBox)tb;
            tb1.GotFocus += TextBox_GotFocus;
        }
    }
}

private void TextBox_GotFocus(object sender, RoutedEventArgs e)
{
    KeyBoardManager.LaunchOnScreenKeyboard();
}

当我想运行此代码时,我有以下错误:

错误1'OSK_Test.MainWindow'不包含'Controls'的定义,也没有扩展方法'Controls'接受类型'OSK_Test.MainWindow'的第一个参数(你是否缺少using指令或程序集引用？)

我有什么需要做的,它有效吗？当然,与LostFocus一样!

我需要将2017.2至2017.3的项目表格更新为新的Vuforia版本(因为新的模型目标).播放器仍然可以正常工作.但是,如果我想为Hololens建立一个UWP应用程序.我收到错误,脚本后端不正确(使用IL2CPP).

Vuforia currently does not support the IL2CPP scripting backend for Windows Store Apps. Please select ".NET" as the scripting backend in the "Other Settings" section of the Player Settings

 UnityEngine.Debug:LogError(Object)
 BuildObserver:OnPreprocessBuild(BuildTarget, String)
 UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

所以我在"设置"中更改为.NET.但现在错误是,IL2CPP构建了修补程序.

UnityException: Build path contains project built with IL2CPP scripting backend, while current project is using .NET scripting backend.
 PostProcessWinRT.CheckSafeProjectOverwrite () (at C:/buildslave/unity/build/PlatformDependent/MetroPlayer/Extensions/Managed/PostProcessWinRT.cs:303)

那我现在该怎么办？我能改变一下吗？

这些是我原来的设置:
