推荐答案

注意 - 不要使用StreamWriter"出于任何原因.

只需使用简单的 File.Write 命令即可.

这是 Unity 中常见的误解！

关于这个话题，一个糟糕的示例代码在 www 上传播了多年.只需使用 File.Write.

关于此页面上的问题，数千"条目绝对没有.

Regarding the question on this page, "thousands" of entries is absolutely nothing.

请注意，例如:您应用中的任何小图标图像都会使您的姓名/地址数据的大小完全相形见绌！

Note that for example: any tiny icon image in your app will completely dwarf the size of your name/address data!

(1) 极其容易保存文本文件:

(1) extremely easy to save a text file:

// IO crib sheet..
// filePath = Application.persistentDataPath+"/"+fileName;
// check if file exists System.IO.File.Exists(f)
// write to file File.WriteAllText(f,t)
// delete the file if needed File.Delete(f)
// read from a file File.ReadAllText(f)

仅此而已.

   string currentText = File.ReadAllText(filePath);

注意...........

NOTE WELL...........

// filePath = Application.persistentDataPath+"/"+fileName;
// YOU MUST USE "Application.persistentDataPath"
// YOU CANNOT USE ANYTHING ELSE/
// NOTHING OTHER THAN "Application.persistentDataPath" WORKS/
// ALL OTHER OPTIONS FAIL ON ALL PLATFORMS/
// YOU CAN >ONLY< USE Application.persistentDataPath IN UNITY.

以您想要的任何方式存储信息，可能是 JSON 或 csv.

Store the info any way you want, probably JSON or csv.

在 Unity 中使用 Json 非常容易，stackoverflow 上有 100 多个示例.

It is dead easy to use Json in Unity, there are 100s of examples on stackoverflow.

(2) 一旦你说了一百万个项目.可以学习使用本地SQL数据库，非常值得学习.按照 Łukasz Motyczka 在评论中所说的去做.

(2) once you have say one million items. you can learn about using the local SQL database, which is well worth learning. Do what Łukasz Motyczka says in the comments.

(3) 永远不要使用 PlayerPrefs - 它更难更乱！

(3) Never use PlayerPrefs - it is much harder and messy!
