It doesn't seem to be adding the item to the collection. Should this syntax work?

I suppose I should use insert correct? I am using an ajax file upload to post images and add them to a list&lt;t&gt; of the class that I created. I cannot use session, so I thought I would use cache and make the cache ID the sessionID so it would be unique. I need to be able to maintain the collection until a submit button is pressed for a from on another method.

You are correct, I did do it correctly, for some reason it wouldn't register the record count on the stepthrough..<br />

Thanks!

<div class="content wysiwyg-content">
I was wondering how i could add or insert items into a cache considering multiple ajax posts in a file upload. <br />
<br />
This does not work:<br />
<br />
((List&lt;RebateImage&gt;)Cache[<wbr />SessionID]<wbr />).Add(new RebateImage { Imagetype = imagetype, Filename = fileName, Imagefile = imagetoupload });<br />
<br />
It works this way with a session (I can't use session due to a cms), but I am looking for this same concept if I assign a List&lt;RebateImage&gt; to a cache Object.

Adding a Collection to the Cache, asp.net, C#

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
