修改路径字符串，以提高耐用性 [英] Modify path string to improve robustness

问题描述

我有一个文件，我的程序从读取数据的一种路径字符串。我想提高稳健性，我记得看到有人这样做。\\布拉布拉\\ blalbla \\但我发现它有点难以找到一个主题，介绍了如何这项工作，所以我可以实现它变成我的计划。

I have a a string for a path for a file my program reads data from. I want to improve the robustness and I recall seeing someone do .\blabla\blalbla\ but I'm finding it a bit hard to find a topic that explains how this work so I can implement it into my program.

我的路径（我知道的命名是不正确的，但它会与我的财产干扰，如果我用大写P把它命名为）

My path (I'm aware that the naming isn't correct but it'd interfere with my property if I named it with a capital P)

private const string path = @"C:\Users\zain\Desktop\program_storage\AccountDatabase.txt";

我想它是这样的 \\ program_storage \\ AccountDatabase.txt （这并不可惜工作），因为它会意味着我可以移动程序各地，而无需更改类的常量字符串。

I'd like it to be something like .\program_storage\AccountDatabase.txt (this doesn't work unfortunately) as it'd mean I can move the program around without having to change the string in the constants class.

任何及所有帮助pciated AP $ P $

Any and all help is appreciated

推荐答案

您可以使用类似下面的存储/读取文件：

You can use something like the following to store/read the file:

var dir = Path.Combine(Environment
    .GetFolderPath(Environment.SpecialFolder.ApplicationData), "MyProgram");
if(!Directory.Exists(dir))
    Directory.CreateDirectory(dir);
var path = Path.Combine(dir, "AccountDatabase.txt");

这将使用或在您的用户帐户的App_Data文件创建一个文件夹，然后返回路径到该文件夹​​中的文件。请参阅 Environment.SpecialFolder 枚举其他位置可能的。

This will use or create a folder in the App_Data of your user account and then return the path to a file in that folder. See the Environment.SpecialFolder enum for other locations possible.
