本文介绍: 一般我们代码生成了之后，就不会动了。而可动的参数一般写在配置文件里面。配置语言的格式一般有一下几种优点缺点xml扩展性强，歧义性小对于人来说过于冗长Json可读性强无法添加注释yaml可读取强缩进地狱,手动修改时极其容易出现问题set;set;getset;if (!/// 创建文件tryRead();throw new Exception(“文件读取失败!请确认是否配置文件格式是否正确”);/// 覆盖文件。
代码
public class MyXmlConfigAutoHelper<T>
{
public T Setting { get; set; }
public string FileName { get; set; } = "MyConfig.xml";
public string BackupName
{

{
var regex = new Regex(@"(w+).(w+)$");
var filename = regex.Match(FileName).Value;
var backName = (new Regex(@".(w+)$")).Split(filename)[0];
var newBackName = backName + "_back";
return (new Regex(backName)).Replace(FileName, newBackName);

测试用例
static void Main(string[] args)
{
var config = new MyConfigService() {
Name = "小坤",
Description="爱坤",
Default = "鲲鲲",
SettingKey = MyConfigService.MyKeys.Banana,
Id = 80086,
IsEnabled = true,
};
var xmlAutoHelper = new MyXmlConfigAutoHelper<MyConfigService>("resource\Myconfig.xml", config);
xmlAutoHelper.AutoInit();
//Console.WriteLine(xmlAutoHelper.BackupName);
Console.WriteLine("运行完成！");
Console.ReadKey();
}
运行结果
由于测试步骤过于复杂，情况比较多，这里就不放截图了。简单来说就是尽可能的使用已有的数据进行还原，如果两个文件都损坏直接使用默认值替换

总结
我这里最后加了个back备份文件，我们平时就修改主要文件的配置即可。如果主要文件损坏，那就备份文件补上。但是这个是主要文件损坏的情况，如果主要文件没损坏，是参数设置错了呢？那我们可以自动生成按照时间戳的备份文件，一次存多个。
- 主要文件
- 备份文件-2024-1-6 17:37:20
- 备份文件-2024-1-6 17:37:30
为了安全考虑的方式是没有上限的。这里就不展开说明了，这里已经写好一个基本的设置文件自动保存，和设置文件自动备份回档的功能，如果想要更高的安全基本可以自己在我的代码上面继续封装。
还有备份文件可以当做缓存文件一样来使用，但是这个是明文存储的。可以自己手动加密一下，反正加密和解密的方法也有很多。可以自己琢磨一下。
