我该怎么办？ [英] How do I do this please?

问题描述

设计一个Windows窗体应用程序，我声明了以下内容 -



String x =;

String [] y = new String [4];



我打算将值传递给x和y，即使在退出程序或关闭计算机后也可以检索。

请指导我如何做到这一点。

谢谢。

Please guide me on how to do this please.

推荐答案

你可以用很多东西来存储东西。



*数据库（远程）

*序列化（二进制文件，本地）

*序列化（文本文件，本地）





要在数据库中存储需要知道sql的东西，你需要拥有一个数据库服务器。

有很多服务器程序，有些是：mysql，postgresql，oraclesql，...



对于序列化我只能给你一些链接：

Yaxlib。 Xml格式，人类可读

一般MS文档

Microsoft的Xml Serializer



或者您可以自己编写序列化程序。

这是一个将String []写入文件并再次读取的示例。请注意，你不能在字符串中使用'〜'。

There are plenty of things you could use to store something.

* Database (Remote)
* Serialize (Binary File, local)
* Serialize (Text File, local)


For storing something in a database you need to know sql, you need to own a database server.
There are plenty of serverprograms out there, some are: mysql, postgresql, oraclesql,...

For Serializing I can only give you some links:
Yaxlib. Xml Format, human Readable
General MS Documentation
Xml Serializer from Microsoft

Or you can write a serializer on your own.
This is a example which writes a String[] to a file and reads it again. Note you can't use '~' in the string.

string[] tok = {"test", "test", "test", "test"};
...
String toFile = "";
foreach (String s in tok) {
    toFile += s + "~";
}

File.WriteAllText("myfile.txt", toFile);

和阅读这可能是你的解决方案：

and for reading this could be your solution:

String text = File.ReadAllText("myfile.txt");
String[] arr = text.Split('~');

您需要将其保存在数据库中。

You need to save it in database.
