    <blockquote> <p>Now what I want to do is Draw a small area on the screen with the items sprite and the total number of that item that I have collected. I am not really interested in the Drawing aspect is more of the extraction of the data in/out of the inventory.</p> </blockquote> <p>Sound like you want to use a linq count.</p> <pre><code>InventoryObjects.Count(inventoryObject =&gt; inventoryObject.Type == ObjectTypes.Asteroid); WorldObjects.Count(worldObject =&gt; worldObject.Type == ObjectTypes.Asteroid); </code></pre> <p>You can think of this like SQL</p> <p>SELECT COUNT([dbo].[World Objects].[Object]) WHERE [dbo].[World Objects].[Type]='Asteroid'</p> <p>However, if you are looking to extract an item and add it to another list, you should take the advice of Reed Copsey.</p> <hr> <p><strong>Edit</strong></p> <p>So assuming that you have a <code>Player</code> Class then perhaps it structure like so,</p> <pre><code>Public Class Player { public List&lt;GamePlayObject&gt; Inventory {get; set;} } </code></pre> <p>You also have a <code>World</code> Class and perhaps it has similar,</p> <pre><code>Public Class World { public List&lt;GamePlayObject&gt; Objects {get; set;} } </code></pre> <p>Your <code>GamePlayObject</code> may look like so,</p> <pre><code>Public Class GamePlayObject { public ObjectType Type {get; set;} } </code></pre> <p>So assuming you've initialized your world and it has several objects, and you know which object you wanted to remove from said World. This is certainly not be the best approach in terms of resources and optimization, (This would be where Reed Copsey's answer would come in handy) but, you could...</p> <pre><code>var targetObject = World.Where(gamePlayObject =&gt; (DesiredConditions)) World.Objects.Remove(targetObject); Player.Inventory.Add(targetObject); </code></pre> <p>Where <code>DesiredConditions</code> would maybe be something like <code>gamePlayObject.IsCollidedWith</code></p> <p>Once you've done this you can query the <code>Player</code>'s inventory.</p> <pre><code>var IronCount = Player.Inventory.Count(gamePlayObject =&gt; gamePlayObject.Type == ObjectType.Iron); </code></pre> <p>Hope this clears things up.</p>

    1. CO+1. This is how I would have answered as well. Except using the `object` keyword as a variable. The compiler won't appreciate that.

    2. COAlex, many thanks but my knowledge of the usage of the above is very and I mean very limited at the moment. If my list has a list of "Iron, Iron, Steel,Gold,Gold,Gold" how can i create the following Iron x 2, Steel x 1 and Gold x 3, hope this makes sense.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
