从代码中获取Windows Phone 7应用程序标题

Question

我想从我的ViewModel代码访问存储在WMAppManifest.xml文件中的Title值.这是通过项目属性设置的相同应用程序标题.

有没有办法从App.Current这样的代码访问代码？

查看Microsoft Silverlight Analytics Framework中 WP7DataCollector.GetAppAttribute()的源代码.GetAppAttribute("Title")将会这样做.

    /// <summary>
    /// Gets an attribute from the Windows Phone App Manifest App element
    /// </summary>
    /// <param name="attributeName">the attribute name</param>
    /// <returns>the attribute value</returns>
    private static string GetAppAttribute(string attributeName)
    {
        string appManifestName = "WMAppManifest.xml";
        string appNodeName = "App";

        var settings = new XmlReaderSettings();
        settings.XmlResolver = new XmlXapResolver();

        using (XmlReader rdr = XmlReader.Create(appManifestName, settings))
        {
            rdr.ReadToDescendant(appNodeName);
            if (!rdr.IsStartElement())
            {
                throw new System.FormatException(appManifestName + " is missing " + appNodeName);
            }

            return rdr.GetAttribute(attributeName);
        }
    }
