If the parameter is -1, it needs to run a different query as to if an ID was specified... how do I do this? I've tried initialising var q; outside the If block but no luck!

 // Loads by Entry ID, or if -1, by latest entry
private void LoadEntryByID(int EntryID)
{
    IEnumerable<tblBlogEntry> q;
    if (EntryID == -1)
    {
        q = (
            from Blog in db.tblBlogEntries
            orderby Blog.date descending
            select new
            {
                Blog.ID,
                Blog.title,
                Blog.entry,
                Blog.date,
                Blog.userID,
                Comments = (
                    from BlogComments in db.tblBlogComments 
                    where BlogComments.blogID == Blog.ID 
                    select BlogComments).Count(),
                Username = (
                    from Users in db.yaf_Users 
                    where Users.UserID == Blog.userID 
                    select new { Users.DisplayName })
            }).FirstOrDefault();
    }
    else
    {
        q = (
            from Blog in db.tblBlogEntries
            where Blog.ID == EntryID
            select new
            {
                Blog.ID,
                Blog.title,
                Blog.entry,
                Blog.date,
                Blog.userID,
                Comments = (
                    from BlogComments in db.tblBlogComments 
                    where BlogComments.blogID == Blog.ID 
                    select BlogComments).Count(),
                Username = (
                    from Users in db.yaf_Users 
                    where Users.UserID == Blog.userID 
                    select new { Users.DisplayName })
            }).SingleOrDefault();
    }
    if (q == null)
    {
        this.Loaded = false;
    }
    else
    {
        this.ID = q.ID;
        this.Title = q.title;
        this.Entry = q.entry;
        this.Date = (DateTime)q.date;
        this.UserID = (int)q.userID;
        this.Loaded = true;
        this.AuthorUsername = q.Username;
    }       
}

My main aim is to reduce repeating code
