When writing a program, you often need to use the project root directory. Summarize yourself as follows
1. Get the root directory method of the console application
Method 1, Environment.currentdirectory Gets or sets the fully qualified path of the current working directory
Method 2, AppDomain.CurrentDomain.BaseDirectory gets the base directory, which is used by the Assembly resolver to probe assemblies
2. Get the root directory method of the Web application
Method 1, HttpRuntime.AppDomainAppPath.ToString ();//Gets the physical drive path of the application directory that hosts the application in the current application domain. Used in App_Data to get
Method 2, Server.MapPath ("") or Server.MapPath ("~/");//returns the physical file path relative to the specified virtual path on the Web server
Method 3, request.applicationpath;//get the virtual application root directory of the ASP.
3. Get the root directory method of the WinForm application
1, Environment.CurrentDirectory.ToString ();//Gets or sets the fully qualified path to the current working directory
2, Application.StartupPath.ToString ();//Gets the path to the executable file that launched the application, not including the name of the executable file
3, Directory.GetCurrentDirectory ();//Gets the current working directory of the application
4. appdomain.currentdomain.basedirectory;//gets the base directory, which is used by the Assembly conflict Resolver to probe assemblies
5. appdomain.currentdomain.setupinformation.applicationbase;//Gets or sets the name of the directory that contains the application
Where: The following two methods can get the name of the execution file
1, Process.getcurrentprocess (). mainmodule.filename;//gets the file name of the EXE that is currently executing.
2. application.executablepath;//gets the path to the executable file that launched the application, including the name of the executable file
