Found not ? After startup and automatic startup

Environment.CurrentDirectory There has been a change ,

In this way, if we used relative paths in our program , You can't find the corresponding file ,

How to deal with ?

Method 1:

Change the current path during program initialization

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

Method 2: Add environment variables , Calculation line -- attribute -- Advanced system setup -- environment variable -- Set in system variable .

 static void Main(string[] args)
{
Console.WriteLine(" More boutique search official account :" + "dotnet Programming ");
Console.WriteLine("C# Technology exchange group :"+" Add small make up WeChat " + "zls20210502");
Console.WriteLine(" Keep your notes in mind : Add group ");
Console.ReadKey();
}
