            with the binding clause whose path points to that string name.

            For example:

                Text="{Binding Path=LocalizedResources.ApplicationTitle, Source={StaticResource LocalizedStrings}}"

            This binding points to the template's string resource named "ApplicationTitle".

            Adding supported languages in the Project Properties tab will create a
            new resx file per language that can carry the translated values of your
            UI strings. The binding in these examples will cause the value of the
            attributes to be drawn from the .resx file that matches the
            CurrentUICulture of the app at run time.

推荐答案

您没有为XAML中的TextBox指定名称。因此，在后面的代码中你无法访问它。

You are not assigning a name to your TextBox in the XAML. Therefore in code behind you can't access it.

TextBox声明如下：

The TextBox is declared like this:

< TextBox Horizo​​ntalAlignment =" Left"高度= QUOT; 72"余量= QUOT; 10,81，-10,0" TextWrapping = QUOT;包覆与QUOT;文本= QUOT;" VerticalAlignment = QUOT;陀螺" Width =" 456" />

<TextBox HorizontalAlignment="Left" Height="72" Margin="10,81,-10,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="456"/>

如果您将其更改为：

< TextBox x：Name =" txtActivationPIN" Horizo​​ntalAlignment =" Left"高度= QUOT; 72"余量= QUOT; 10,81，-10,0" TextWrapping = QUOT;包覆与QUOT;文本= QUOT;" VerticalAlignment = QUOT;陀螺" Width =" 456" />

<TextBox x:Name="txtActivationPIN" HorizontalAlignment="Left" Height="72" Margin="10,81,-10,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="456"/>

它应该有效。我没有看过你的其余代码，但这应该可以解决你在编译过程中遇到的问题。

It should work. I have not looked at the rest of your code but this should fix the problem you get during compilation.
