private string[] GetAssemblyLocation(string[] assemblyNames){string[] locations = new string[assemblyNames.Length];for (int loop = 0; loop <= assemblyNames.Length - 1; loop++){locations[loop] = AppDomain.CurrentDomain.GetAssemblies().Where(a => !a.IsDynamic && a.ManifestModule.Name == assemblyNames[loop]).Select(a => a.Location).FirstOrDefault();}return locations;}


USAGE: 

 string reportPath = GetAssemblyLocation(new string[] { "Reports.dll" })[0];

  System.Reflection.Assembly assembly = Assembly.LoadFrom( reportPath);
