Like this:

<pre><code>bins.Where(b =&gt; b.Components.Any( c =&gt; new[]{1,2,3}.Contains(c.ComponentId) )
</code></pre>

If you need all:

<pre><code>bins.Where(b =&gt; b.Components.All( c =&gt; new[]{1,2,3}.Any( i =&gt; i == c.ComponentId) ))
</code></pre>

Or if you need that some items in the list has this items:

<pre><code>bins.Where(b =&gt; new[]{1,2,3}.All(i =&gt; b.Components.Any(c =&gt; i == c.ComponentId) ))
</code></pre>

You can combine all/any/contains in sub query as you want

<pre><code>bins.Where(x =&gt; x.Components.Any(y =&gt; y.ComponentId ==1 || y.ComponentId == 2 || y.ComponentId == 3))
</code></pre>

Try this one.

If you have list of integers then you can modify last conditions like below.

<pre><code>y =&gt; list.Any(z =&gt; y.ComponentId == z)
</code></pre>

Or something like this.

<pre><code>y =&gt; list.Contains(y.ComponentId)
</code></pre>

These conditions are to contain at least one component id. If you want to contain all component ids you can use <code>All</code> method instead of <code>Any</code>

<pre><code>var bins = new List&lt;Bin&gt;();
var ids = new List&lt;int&gt; { 1, 2, 3 };

// go through each bin and make sure it has all the items in ids
bins.Where(x =&gt; ids.All(id =&gt; x.Components.Select(c =&gt; 
 c.ComponentId).Contains(id)));
</code></pre>

I have the following classes.

<pre><code>public class Bin
{
 public int BinId { get; set; }
 public IEnumerable&lt;Component&gt; Components { get; set; }
}

public class Component 
{
 public int ComponentId { get; set; }
 public string ComponentName { get; set; }
}
</code></pre>

Using LINQ how do I find all <code>Bin</code> objects that contain specific set of components, say components with IDs 1, 2, 3?

Edit

Just to clarify all IDs must be present in a <code>Bin</code>. Also I have a collection that contains IDs to match.

Select objects that contain specific child elements
