How to get the location of the DLL currently executing

Question

I have a config file that I need to load as part of the execution of a dll I am writing   The problem I am having is that the place I put the dll and config file is not the  current location  when the app is running   For example  I put the dll and xml file here      D  Program Files Microsoft Team Foundation Server 2010 Application Tier Web Services bin Plugins   But if I try to reference the xml file  in my dll  like this   XDocument doc   XDocument Load     AggregatorItems xml     then   AggregatorItems xml translates to      C  windows system32 inetsrv AggregatorItems xml   So  I need to find a way  I hope  of knowing where the dll that is currently executing is located   Basically I am looking for this   XDocument doc   XDocument Load CoolDLLClass CurrentDirectory    AggregatorItems xml

Reflection is your friend  as has been pointed out  But you need to use the correct method   Assembly GetEntryAssembly         gives you the entrypoint assembly for the process  Assembly GetCallingAssembly        gives you the assembly from which the current method was called  Assembly GetExecutingAssembly      gives you the assembly in which the currently executing code is defined Assembly GetAssembly  Type t       gives you the assembly in which the specified type is defined

You are looking for System Reflection Assembly GetExecutingAssembly    string assemblyFolder   Path GetDirectoryName Assembly GetExecutingAssembly   Location   string xmlFileName   Path Combine assemblyFolder  AggregatorItems xml      Note   The  Location property returns the location of the currently running DLL file   Under some conditions the DLL is shadow copied before execution  and the  Location property will return the path of the copy  If you want the path of the original DLL  use the Assembly GetExecutingAssembly   CodeBase property instead    CodeBase contains a prefix  file     which you may need to remove

If you re working with an asp net application and you want to locate assemblies when using the debugger  they are usually put into some temp directory  I wrote the this method to help with that scenario   private string   GetAssembly string   assemblyNames        string    locations   new string assemblyNames Length         for  int loop   0  loop  lt   assemblyNames Length - 1  loop                          locations loop    AppDomain CurrentDomain GetAssemblies   Where a   gt   a IsDynamic  amp  amp  a ManifestModule Name    assemblyNames loop   Select a   gt  a Location  FirstOrDefault              return locations      For more details see this blog post http   nodogmablog bryanhogan net 2015 05 finding-the-location-of-a-running-assembly-in-net   If you can t change the source code  or redeploy  but you can examine the running processes on the computer use Process Explorer  I written a detailed description here   It will list all executing dlls on the system  you may need to determine the process id of your running application  but that is usually not too difficult    I ve written a full description of how do this for a dll inside IIS - http   nodogmablog bryanhogan net 2016 09 locating-and-checking-an-executing-dll-on-a-running-web-server
