    copied!<p>I know there are a lot of examples of this on the web, but I can't seem to get this to work.</p> <p>Let me try to set this up, I have a list of custom objects that I need to have limited on a range of values. </p> <p>I have a sort variable that changes based on some action on the UI, and I need to process the object differently based on that.</p> <p>Here is my object:</p> <pre><code>MyObject.ID - Just an identifier MyObject.Cost - The cost of the object. MyObject.Name - The name of the object. </code></pre> <p>Now I need to filter this based on a range in the cost, so I will have something similar to this, considering that I could be limiting by Either of my bottom two properties.</p> <pre><code>var product = from mo in myobject where mo.Cost &lt;= 10000 </code></pre> <p>or</p> <pre><code>var product = from mo in myobject where mo.Name equals strName </code></pre> <p>Now I have the dynamic linq in my project, but I'm not figuring out how to get it to actually work, as when I do some of the examples I am only getting:</p> <pre><code>Func&lt;Tsourse&gt;bool&gt; predicate </code></pre> <p>as an option.</p> <p><strong>Update:</strong> I am trying to find a solution that helps me Objectify my code, as right now it is a lot of copy and paste for my linq queries.</p> <p><strong>Update 2:</strong> Is there an obvious performance difference between:<br /></p> <pre><code>var product = from mo in myobject ... a few joins ... where mo.Cost &lt;= 10000 </code></pre> <p>and</p> <pre><code>var product = (from mo in myobject ... a few joins ...) .AsQueryable() .Where("Cost &gt; 1000") </code></pre>
