To get the bin directory, string path = Assembly.GetExecutingAssembly().Location;
does NOT always work (especially when the executing assembly has been placed in an ASP.NET temporary directory).
Instead, you should use string binPath = System.IO.Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, "bin");
Further, you should probably take the FileLoadException and BadImageFormatException into consideration.
Here is my working function:
public static void LoadAllBinDirectoryAssemblies()
{
string binPath = System.IO.Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, "bin"); // note: don't use CurrentEntryAssembly or anything like that.
foreach (string dll in Directory.GetFiles(binPath, "*.dll", SearchOption.AllDirectories))
{
try
{
Assembly loadedAssembly = Assembly.LoadFile(dll);
}
catch (FileLoadException loadEx)
{ } // The Assembly has already been loaded.
catch (BadImageFormatException imgEx)
{ } // If a BadImageFormatException exception is thrown, the file is not an assembly.
} // foreach dll
}
