I have the below code which is throwing a BadImageFormatException
. The DLL it's loading is 32bit. The web server is running Windows 64bit but the application pool is set to Enable 32 bit. Is there any way I can get this to work?
public class HomeController : Controller
{
[DllImport("CDCrypt.dll")]
[return: MarshalAs(UnmanagedType.LPStr)]
public static extern String Encrypt
([MarshalAs(UnmanagedType.LPStr)] String aName);
[DllImport("CDCrypt.dll")]
[return: MarshalAs(UnmanagedType.LPStr)]
public static extern String Decrypt
([MarshalAs(UnmanagedType.LPStr)] String aName);
public ActionResult Index()
{
try
{
ViewBag.EncryptString = Encrypt("test");
}
catch (Exception e)
{
ViewBag.EncryptString =
"Stack Trace\r\n:" + "\r\nException: " + e.Message;
return new HttpStatusCodeResult(500);
}
return Vie开发者_JS百科w();
}
public ActionResult Up()
{
ViewBag.Up = "You can see me";
return View();
}
}
Both the library and the consumer have to be the same. So determine what your lib you are calling is and ensure you are compiling for that type. Now - IIS itself (at least v 6) can only run one mode OR the other for everything so it either needs to be set for 64 or 32 bit across the board . See this http://support.microsoft.com/kb/894435
