Assembly.GetExecutingAssembly().Location

Gets the location of the executing assembly. In an ASP.NET application this could vary due to shadow copying assemblies in system folders. The location of the currently executing assembly could be different than the location of the hosting process.

Directory.GetCurrentDirectory();

Gets the current working directory of the hosting process. In most cases this will be the directory where the executable is located but this working directory could be modified programatically using the SetCurrentDirectory method.

System.Environment.CurrentDirectory;

The directory from which the hosting process was started.

In a desktop application where you have everything in the same folder the 3 might return the same.

The current directory is the working directory, it's not necessarily the same as the directory that contains your assembly.

For example, if you were on the command line, in the root C:\ drive and did the command "SomeFolder\MyProgram.exe" the current directory would still be C:\

  1. Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) returns a folder of specified assembly.

  2. Directory.GetCurrentDirectory() gets the system current directory without backslash, according to MSDN. Directory.GetCurrentDirectory()

  3. System.Environment.CurrentDirectory gets or sets system current directory.
