How do I get the path of the assembly the code is in?

Question

Is there a way to get the path for the assembly in which the current code resides? I do not want the path of the calling assembly, just the one containing the code.

Answer 1

AppDomain.CurrentDomain.BaseDirectory

works with MbUnit GUI.

Answer 2

This should work:

ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
Assembly asm = Assembly.GetCallingAssembly();
String path = Path.GetDirectoryName(new Uri(asm.EscapedCodeBase).LocalPath);

string strLog4NetConfigPath = System.IO.Path.Combine(path, "log4net.config");

I am using this to deploy DLL file libraries along with some configuration file (this is to use log4net from within the DLL file).

Answer 3

Web application?

Server.MapPath("~/MyDir/MyFile.ext")

Answer 4

As far as I can tell, most of the other answers have a few problems.

The correct way to do this for a disk-based (as opposed to web-based), non-GACed assembly is to use the currently executing assembly's CodeBase property.

This returns a URL (file://). Instead of messing around with string manipulation or UnescapeDataString, this can be converted with minimal fuss by leveraging the LocalPath property of Uri.

var codeBaseUrl = Assembly.GetExecutingAssembly().CodeBase;
var filePathToCodeBase = new Uri(codeBaseUrl).LocalPath;
var directoryPath = Path.GetDirectoryName(filePathToCodeBase);

Answer 5

Does this help?

//get the full location of the assembly with DaoTests in it
string fullPath = System.Reflection.Assembly.GetAssembly(typeof(DaoTests)).Location;

//get the folder that's in
string theDirectory = Path.GetDirectoryName( fullPath );

Answer 6

It's as simple as this:

var dir = AppDomain.CurrentDomain.BaseDirectory;
