ASP.NET Trouble importing a DLL

Question

I'm having a lot of trouble importing a DLL to use. I have an aspx page with no code behind, no virtual directories.

All I know about the DLL is it's filename 'GenerateExcel.dll' and namespace 'Xander.Utilities'. How do I import it with either of these

<%@ Assembly Src="./bin/GenerateExcel.dll" %> <%@ Import Namespace="Xander.Utilities" %>

It's not working. I read the other threads on SO and still having trouble.

EDIT: I use it like this:

<script runat="server"> protected void Page_Load(object sender, EventArgs e) { //... Xander.Utilities.ExcelMaker em = new Xander.Utilities.ExcelMaker(); //... }

I'm not sure if this will work as I don't have your assembly, but you could try with or without the TagPrefix:

<%@ Register Assembly="GenerateExcel" Namespace="Xander.Utilities" TagPrefix="Util" %>

I'm pretty sure that should do it. Would have been my answer had you not beaten me to the punch! +1

You might need to register the assembly in your Web.config file, or you could always add a code behind page...

I see that the DLL shows up in your bin directory. Did you add the DLL as a reference?

to call a dll from your program you need to include the System.Runtime.InteropServices classes

try:

using System.Runtime.InteropServices [DllImport("name.dll")] private static extern int FunctionNameInDll();

The answer was to do an <%@ Import Namespace="Xander.Utilities" %> and then put the DLL in the root's bin folder.

Which file did you put that line into?

The ASPX page; for this small project there were no codebehinds.
