发现没?开机自动启动后

Environment.CurrentDirectory 发生了变更,

这样在在我们程序中原本如果使用相对路径进行处理的,就找不见相应的文件了,

怎么处理?

方法1:

在程序初始化的时候改变下当前路径

 public Form1()         {             InitializeComponent();            Environment.CurrentDirectory = AppDomain.CurrentDomain.BaseDirectory;         } 

  方法2:添加环境变量 , 计算行–属性–高级系统设置–环境变量–系统变量里面设置.

  static void Main(string[] args)         {             Console.WriteLine("更多精品搜索公众号:" + "dotnet编程大全");             Console.WriteLine("C#技术交流群:"+"添加小编微信" + "zls20210502");             Console.WriteLine("切记备注:加群");             Console.ReadKey();         }
