Cast list to generic type?

I'm very proud of myself for this:

I didn't explain it fully, but the methods do need to do different things to get the base type or list type setting. I could have shunted this down to the Configuration class, but I had already started creating a second List method anyway.

Separating the <list<T>> from the <T> method is prolly a good thing anyway so each method doesn't get too complex

//This is an object in my MembershipUserClass
public T GetCompanySetting<t>(string key)
{
    //Check if the generic type
    if (typeof (T).IsGenericType && typeof (T).GetInterfaces().Contains(typeof (System.Collections.IEnumerable)))
    {
        //Assume the enumerable is generic.  The caller should know this
        var t = typeof (T).GetGenericArguments()[0];

        //Only way to use t is with reflection (this was the knowledge I was missing)
        MethodInfo method = typeof (Configuration).GetMethod("QueryList").MakeGenericMethod(new[] {t});

        //Convert works fine here 
        return (T)method.Invoke(null,new object []{ CompanyId, null, "AccountManagement", key, null});
    }
    //Normal call with T not enumerable.  This method does check for nullable types so it will return the correct default if the setting does not exist.  Again, the caller should know this
    return Configuration.Query<t>(CompanyId, null, "AccountManagement", key);
}

</t></t>

I wanted this method to be "on rails" for the caller. My colleague who will use this method writes in VB and isn't too familiar with generics.

Thanks for taking a look, guys ^_^
