Testing for a Tridion component link type (binary or component) for conditional linking

Question

I've searched through the Razor mediation documentation and SDL Tridion 2013 documentation, and can't seem to find the answer to my question.

What I'm attempting to do: Test the value of a component link in my template building block and determine if its component type is either "component" or "binary"; and then I'd like to use that information to add a target attribute depending upon the component type (component: _self, binary: _blank).

Code context:

@foreach (dynamic c in @Component.Fields.HeaderLinks) 
{
    if (@c.Link.ExternalLink != null && @c.Link.InternalLink == null) 
    {
        <li><a href="@c.Link.ExternalLink" target="_blank">@c.LinkDisplayName</a></li>
    }
    else 
    {
        <li><tcdl:Link type="Component" destination="@c.Link.InternalLink" 
        templateURI="tcm:0-0-0" linkAttributes="" textOnFail="True" 
        addAnchor="False">@c.LinkDisplayName</tcdl:Link></li>                               
    }
}

I'd love to be able to get the component type, and conditionally assign the target to a string variable based upon type, something like:

if (@c.Link.InternalLink.ComponentLinkType == binary) 
{
    String target = "_blank";
}

or something along those lines, and then just use the variable in the linkAttributes value within <tcdl:Link> something like...

<tcdl:Link ... linkAttributes="@target">@c.LinkDisplayName</tcdl:Link>

You could test for specific Schema's for example

if (c.Link.InternalLink.Schema.Title == "Multimedia Schema Title") 

This would give you more control if the desired output is different based on Multimedia type (e.g. image, document, video, podcast, etc..)

You could also use

if(c.Link.InternalLink.TridionObject.ComponentType.ToString() =="Multimedia")

or

if(c.Link.InternalLink.Schema.Purpose == "Multimedia")
