Get the current path 7 Methods

Code

// Get the full path of the module .
string path1 = System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName;
// Get and set the current directory ( The directory from which the process starts ) The fully qualified directory of 
string path2 = System.Environment.CurrentDirectory;
// Get the current working directory of the application 
string path3 = System.IO.Directory.GetCurrentDirectory();
// Get the base directory of the program 
string path4 = System.AppDomain.CurrentDomain.BaseDirectory;
// Gets and sets the name of the directory that includes the application 
string path5 = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase;
// Get the path of the executable file that started the application 
string path6 = System.Windows.Forms.Application.StartupPath;
// Get the path and file name of the executable file that started the application 
string path7 = System.Windows.Forms.Application.ExecutablePath;

StringBuilder str=new StringBuilder();

1. Net Framework in System.IO.Directory.GetCurrentDirectory() Method is used to get the current working directory of the application . If you use this method to get the directory where the application is located , It should be noted ：System.IO.Directory.GetCurrentDirectory() The directory path obtained by the method follows OpenFileDialog、SaveFileDialog And so on （ Switch working directory ）. Every time you open the folder or use explorer to view the file , Will change the value obtained by this method .
2. and System.Windows.Forms.Application.StartupPath or System.AppDomain.CurrentDomain.BaseDirectory You can get the directory where the application runs , It doesn't change with the folder you open . It is only related to the application running directory , Its value is equal to the root directory of the application startup . For example, you installed the program in C:\Program Files\ Program folder Under the position of , So he is System.Windows.Forms.Application.StartupPath Value .
