I see that my add-ins are installed to C:\Users\Me\AppData\Local\ESRI\Desktop10.0\AssemblyCache{6C90269B-D233-4122-3747-C2AE1131E22C}

Is it possible to find that file path from within the Add-in itself? e.g., someone would click a button and it would tell them the path where the add-in is located.

I want to use this location to store user-defined configuration info.

  • won't let me post my own answer yet, so here it is: This returns full path to the .dll Public Function FindMe() As String FindMe = System.Reflection.Assembly.GetExecutingAssembly().Location ' MsgBox(FindMe) return FindMe End Function – user4979 Nov 30 '11 at 19:04

    You might consider creating a well-known folder under %APPDATA% to store user configuration data rather than in the AssemblyCache folder as this is subject to deletion by the add-in framework and as you have seen requires reflection to determine. – blah238 Nov 30 '11 at 20:30

    @user4979: you might want to check out this question if you are looking at adding user scoped settings: gis.stackexchange.com/questions/9001/… – Jay Cummins Nov 30 '11 at 21:51
  • @blah238 user4979 has not been seen here for over 3 years, and I do not have the knowledge to translate their (and/or your) comment into an answer. Could you perhaps do so sometime? – PolyGeo Feb 15 '15 at 1:46
  • @PolyGeo It was not an answer, just a suggestion. – blah238 Feb 15 '15 at 15:01

Here is the C# code to get the addin assembly folder:

public static string AssemblyDirectory
                string codeBase = Assembly.GetExecutingAssembly().CodeBase;
                UriBuilder uri = new UriBuilder(codeBase);
                string path = Uri.UnescapeDataString(uri.Path);
                return Path.GetDirectoryName(path);

and VB.NET:

Public Shared ReadOnly Property AssemblyDirectory() As String
        Dim codeBase As String = Assembly.GetExecutingAssembly().CodeBase
        Dim uri__1 As New UriBuilder(codeBase)
        Dim path__2 As String = Uri.UnescapeDataString(uri__1.Path)
        Return Path.GetDirectoryName(path__2)
    End Get
End Property

If you are using Python, you can find the folder location by doing the following

import os
print os.path.dirname(__file__)
