Ways to get the current path in C #

String AppPath = System.Reflection.Assembly.GetExecutingAssembly (). GetName (). CodeBase; Get the entire file path name
AppPath = AppPath. Substring (0, AppPath. LastIndexOf (@ "\")); Remove/Follow the program name
MessageBox.Show (AppPath);

1. System.Diagnostics.Process.GetCurrentProcess (). Mainmodule.filename
Gets the full path of the module. Gets the file name of the EXE that is currently executing.

2. System.Environment.CurrentDirectory
Gets and sets the fully qualified directory of the current directory (the directory from which the process starts).

Note:
By definition, if the process is started in the root directory of a local or network drive, the value of this property is the drive name followed by a trailing backslash (such as "C: \"). If the process is started in a subdirectory, the value of this property is the drive and subdirectory path (such as "C:\mySubDirectory") without trailing backslashes.
In addition, if a program that uses the method is called in another program, the value obtained by the method is the same path as the other program.

3. System.IO.Directory.GetCurrentDirectory ()
Gets the current working directory of the application. This is not necessarily the directory from which the program starts, ah, it is possible that the program is placed in C:\www, this function may return C:\Documents and settings\zyb\, or C:\Program files\adobe\, sometimes not necessarily return something, I don't understand it either.

Note: The value of this method is not fixed, with the OpenFileDialog, SaveFileDialog and other objects determined by the directory and change.

2 and 3 have the same effect.
4. System.AppDomain.CurrentDomain.BaseDirectory
Gets the base directory of the program. Gets the base directory that is used by the Assembly resolver to probe assemblies.

5. System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase
Gets and sets the name of the directory that contains the application.

6. System.Windows.Forms.Application.StartupPath
Gets the path to the executable file that launched the application, not including the name of the executable file. The effect is the same as 4, 5. Just 5 of the string returned is a "\" more.

7. System.Windows.Forms.Application.ExecutablePath
Gets the path to the executable file that launched the application, including the name of the executable file. Gets the path and file name of the executable file that launched the application, with the same effect as 1.

code example:
Gets the full path of the new process component and its main module associated with the currently active process, including the file name (process name).
String str = System.Diagnostics.Process.GetCurrentProcess (). Mainmodule.filename;
Result:x:\xxx\xxx\xxx.exe (. exe file in the same directory as +.exe filename)

Gets and sets the fully qualified path to the current directory (that is, the directory from which the process starts).
string str = System.Environment.CurrentDirectory;
Result:x:\xxx\xxx (the directory where the. exe file resides)

Gets the base directory of the current application domain for Thread, which is used by the Assembly resolver to probe assemblies.
string str = System.AppDomain.CurrentDomain.BaseDirectory;
Result:x:\xxx\xxx\ (the directory where the. exe file is located + "\")

Gets and sets the name of the directory that contains the application.
string str = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase;
Result:x:\xxx\xxx\ (the directory where the. exe file is located + "\")

Gets the path to the executable file that launched the application, not including the name of the executable file.
string str = System.Windows.Forms.Application.StartupPath;
Result:x:\xxx\xxx (the directory where the. exe file resides)

Gets the path to the executable file that launched the application, including the name of the executable file.
string str = System.Windows.Forms.Application.ExecutablePath;
Result:x:\xxx\xxx\xxx.exe (. exe file in the same directory as +.exe filename)

Gets the current working directory of the application (unreliable).
String str = System.IO.Directory.GetCurrentDirectory ();
Result:x:\xxx\xxx (the directory where the. exe file resides)
