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.

Same as John's answer, but a slightly less verbose extension method.

public static string GetDirectoryPath(this Assembly assembly)
{
    string filePath = new Uri(assembly.CodeBase).LocalPath;
    return Path.GetDirectoryName(filePath);            
}

Now you can do:

var localDir = Assembly.GetExecutingAssembly().GetDirectoryPath();

or if you prefer:

var localDir = typeof(DaoTests).Assembly.GetDirectoryPath();
