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

How about this ...

string ThisdllDirectory = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);

Then just hack off what you do not need

Answer 2

Here is a VB.NET port of John Sibly's code. Visual Basic is not case sensitive, so a couple of his variable names were colliding with type names.

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

Answer 3

You will get incorrect directory if a path contains the '#' symbol. So I use a modification of the John Sibly answer that is combination UriBuilder.Path and UriBuilder.Fragment:

public static string AssemblyDirectory
{
    get
    {
        string codeBase = Assembly.GetExecutingAssembly().CodeBase;
        UriBuilder uri = new UriBuilder(codeBase);
        //modification of the John Sibly answer    
        string path = Uri.UnescapeDataString(uri.Path.Replace("/", "\\") + 
          uri.Fragment.Replace("/", "\\"));
        return Path.GetDirectoryName(path);
     }
}

Starting with .net framework 4.6 / .net core 1.0, there is now a AppContext.BaseDirectory, which should give the same result as AppDomain.CurrentDomain.BaseDirectory, except that AppDomains were not part of the .net core 1.x /.net standard 1.x API.

AppContext.BaseDirectory

Answer 5

You can get the bin path by AppDomain.CurrentDomain.RelativeSearchPath

Answer 6

string path = Path.GetDirectoryName(typeof(DaoTests).Module.FullyQualifiedName);
