Question

我在我的WPF应用程序中使用此库进行本地化： http://wpflocalizeextension.codeplex.com/

它具有从我的xaml定义中获取绑定资源键的功能，例如：

XAML：

<Button Content="{lex:loc Assembly:ResourceFile:ResourceKey}" Click="Button_Click" />
<Button Content="{lex:loc Assembly:ResourceFile:ResourceKey111}" Click="Button_Click" />
<Button Content="{lex:loc Assembly:ResourceFile:ResourceKey112}" Click="Button_Click" />
<Button Content="{lex:loc Assembly:ResourceFile:ResourceKey113}" Click="Button_Click" />
<Button Content="{lex:loc Assembly:ResourceFile:ResourceKey114}" Click="Button_Click" />
<Button Content="{lex:loc Assembly:ResourceFile:ResourceKey115}" Click="Button_Click" />

代码背后：

private void Button_Click (object sender, RoutedEventArgs e)
{
    var bound = LocExtension.GetBoundExtension(sender, ContentPresenter.ContentProperty.Name);
    if (bound == null)
        return;

    var key = bound.Key;
    var resourceIdentifierKey = bound.ResourceIdentifierKey;
}

正如您所见，我可以获得Key以及ResourceIdentifierKey，现在我希望能够将此绑定键与给定键进行比较：

例如：

private void Button_Click (object sender, RoutedEventArgs e)
{
    var bound = LocExtension.GetBoundExtension(sender, ContentPresenter.ContentProperty.Name);
    if (bound == null)
        return;

    var key = bound.Key;
    var resourceIdentifierKey = bound.ResourceIdentifierKey;

    if (key == "Assembly:ResourceFile:ResourceKey")
        //do something...
    if (key == "Assembly:ResourceFile:ResourceKey111")
        //do something else...
    if (key == "Assembly:ResourceFile:ResourceKey112")
        //do something else...
    if (key == "Assembly:ResourceFile:ResourceKey113")
        //do something else...
    if (key == "Assembly:ResourceFile:ResourceKey114")
        //do something else...
    if (key == "Assembly:ResourceFile:ResourceKey115")
        //do something else...
}

此实现会导致魔术字符串，并且您可能无法在重命名时获取所有这些字符串。我还可以像这样与已解决的值进行比较：

private void Button_Click (object sender, RoutedEventArgs e)
{
    var bound = LocExtension.GetBoundExtension(sender, ContentPresenter.ContentProperty.Name);
    if (bound == null)
        return;

    var key = bound.Key;
    var resourceIdentifierKey = bound.ResourceIdentifierKey;

    string value = null;
    key.ResolveLocalizedValue<string>(out value);

    if (value == Properties.ResourceFile.ResourceKey)
        //do something...
    if (value == Properties.ResourceFile.ResourceKey111)
        //do something else...
    if (value == Properties.ResourceFile.ResourceKey112)
        //do something else...
    if (value == Properties.ResourceFile.ResourceKey113)
        //do something else...
    if (value == Properties.ResourceFile.ResourceKey114)
        //do something else...
    if (value == Properties.ResourceFile.ResourceKey115)
        //do something else...
}

这可以防止魔术字符串，因为它使用了从应用程序中的资源处理自动生成的Properties类，但这使得在2个不同的键中具有相同值的可能性很小，但代码应该对这些键执行不同的操作。 / p>

所以我的问题是，是否有可能让Key像价值一样简单（伪代码）

Properties.ResourceFile.Keys.ResourceKey

或

Properties.ResourceFile.ResourceKey.Name

您可以使用所需的所有键创建单独的类

public class MyResourceKeys {
    public static string ResourceKey { get { return "ResourceKey"; } }
    public static string ResourceKey111 { get { return "ResourceKey111"; } }
    public static string ResourceKey112 { get { return "ResourceKey112"; } }
    ...
}

然后使用它

if (key == MyResourceKeys.ResourceKey) {
    ...
}

获取ResourceKey而不是翻译的值
