如何逐行读取文本文件 Windows RT? [英] How to read a text file line by line Windows RT?

问题描述

我无法找到有关如何在 Windows RT(适用于 Windows 8 应用商店)中逐行读取文本文件的清晰解释.

i just cant find a clean explanation on how to read a text file, line by line in Windows RT ( for Windows 8 Store).

假设我有一个文件夹:MyFolder/Notes.txt

我想从 Notes.txt 中读取数据并将其添加到字符串数组中.

And i want to read the data from Notes.txt and add it to an array of strings.

我如何读/写那个文件?我之前用过 StreamReader，但现在很混乱.而开发示例并没有多大帮助.

How do i read/write from that file? I was using StreamReader before, but now it is very confusing. And the dev samples dont help that much.

推荐答案

我自己设法找到了答案.感谢您的帮助.

    // READ FILE
    public async void ReadFile()
    {
        // settings
        var path = @"MyFolderMyFile.txt";
        var folder = Windows.ApplicationModel.Package.Current.InstalledLocation;


        // acquire file
        var file = await folder.GetFileAsync(path);
        var readFile = await Windows.Storage.FileIO.ReadLinesAsync(file);
        foreach (var line in readFile)
        {
            Debug.WriteLine("" + line.Split(';')[0]);
        }
     }
