Creating a tag cloud out of taglink?

Question

I'm using ASP.NET MVC3 to create a blog and I want to create a tagCloud for it.

Now my question is how I get it into a list (do I need to?), count and then print it out in different sizes?

EDIT:

I have now able to count every tag in every post with following:

Dictionary<string, int> tagLista = new Dictionary<string, int>();

    foreach (Post post in Model)
    {
        foreach (Tag tag in post.Tags)
        {
            if (!tagLista.ContainsKey(tag.Name))
            {
                tagLista[tag.Name] = 1;
            }
            else
            {
                tagLista[tag.Name] += 1;
            }
        }
    }
    //Print out diff. sizes depending on count
    foreach (KeyValuePair<string, int> pair in tagLista)
    {

        if (pair.Value <= 2)
        {
                        <a class="minSize" href="@Href("~/Posts/Tags/" + pair.Key)">@pair.Key</a>
        }

        if (pair.Value > 2 && pair.Value <= 4)
        {
                        <a class="medSize" href="@Href("~/Posts/Tags/" + pair.Key)">@pair.Key</a>
        }
        if (pair.Value > 4 && pair.Value >= 6)
        {
                        <a class="maxSize" href="@Href("~/Posts/Tags/" + pair.Key)">@pair.Key</a> 
        }
    }

The problem here is now that it only shows the tags of all posts on the current page, and not all tags from the database. How should I do instead? On the top of this view(Index) I use:

@using Blog.Models;
@model IEnumerable<Post>

Thanks for any help!
