问题描述

我的应用程序附带了一个文本文件，我想在屏幕上显示其内容.有人知道该怎么做吗?通常的文件IO似乎不适用于Metro.

I've got a text file that ships with my app and I want to display its contents on the screen. Anyone know how to do that? The usual file IO doesn't seem to work for Metro.

谢谢

推荐答案

在我的应用程序中，我正在读取该应用程序随附的XML文件，您可以对其进行调整以读取任何类型的文件

In my app I am reading a XML file that comes with the app, you can tweak it to read any type of file

public class LocalStorage
{
    private const string SyndicationFeedCategoriesFileName = "FeedCategories.xml";

    private StorageFile _storageFile;
    private StorageFolder _storageFolder;
    public async Task<XmlDocument> Read_categories_from_disk()
    {

        try
        {
            _storageFolder = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFolderAsync("Xml");
            _storageFile = await _storageFolder.GetFileAsync(SyndicationFeedCategoriesFileName);

            var loadSettings = new XmlLoadSettings
                                   {ProhibitDtd = false, ResolveExternals = false};
            return await XmlDocument.LoadFromFileAsync(_storageFile, loadSettings);
        }
        catch (Exception)
        {
            return null;
        }
    }
}
