我的 UWP 应用无法读取 txt 文件 [英] My UWP app won't read a txt file

问题描述

我想知道是否有人知道如何让通用 Windows 应用程序读取 txt 文件.

I was wondering if anyone would know how to get an Universal Windows app to read a txt file.

StreamReader lezer = new StreamReader(@"C:\Users\LotteDiesveld\Documents\Visual Studio 2015\Projects\Jaar 1\Periode 2\OIS 12\Eindopdracht\Personen.txt");
tbPersonen.Items.Add(lezer.ReadToEnd());

我也试过这个

StorageFile file = await StorageFile.GetFileFromApplicationUriAsync("ms-appx:///reserveringen.txt")

我知道关于这个主题已经给出了多个答案，但都没有奏效，因为我不断收到错误消息.此错误是无法将类型字符串转换为类型 uri"或无法将类型字符串转换为类型流".

I know multiple answers have been given on this subject, but none work, because I keep getting an error. This error is either "Cannot convert type string to type uri" or "cannnot convert type string to type stream".

推荐答案

UWP 应用在沙盒环境中运行，无权从硬盘驱动器上的任何位置读取文件.如果您想读取用户文档库中的文件，您应该让用户使用选择器选择文件或在应用程序清单中声明文件夹.有关更多信息，请参阅 Jerry Nixon 的博客文章:http://blog.jerrynixon.com/2012/06/windows-8-how-to-read-files-in-winrt.html

A UWP app runs in a sandboxed environment and has no permissions to read a file from anywhere on the hard drive. If you want to read a file in the user's Documents Library you should either let the user select the file using a picker or declare the folder in the application's manifest.
