.Net is not my strong area but try this

Dim vstr as string = "trees, cars, houses"

Dim words as string = vstr.Split(',');

Dim item as string

For Each item In words
	Response.write '<a href="/category.aspx?c=" & item & '">' & item & '</a>'
Next

Have provided with 2 different output example, one does response.write to <a href> tab and another one take .NET approach and binds data to repeater.

// CODE BEHIND .cs file
protected void Page_Load(object sender, EventArgs e)
        {
            // Output to <A HREF> tag
            System.Text.StringBuilder abc = createHrefSample1("trees, cars, houses");
            Response.Write(abc.ToString());


            // Output to Repeater
            System.Data.DataTable pDT = new System.Data.DataTable();
            pDT = createHrefSample2("trees, cars, houses");

            Repeater1.DataSource = pDT;
            Repeater1.DataBind();
        }

        private System.Text.StringBuilder createHrefSample1(string sCategory)
        {
            System.Text.StringBuilder sLinkCategory = new System.Text.StringBuilder();
            string[] SCategory = sCategory.Split(',');

            foreach (string element in SCategory)
            {
                sLinkCategory.Append("<a href='/category.aspx?c=" + element.ToString().Trim() + "'>" + element.ToString().Trim() + "</a>");
            }

            return sLinkCategory;
        }

        public System.Data.DataTable createHrefSample2(string sCategory)
        {
            System.Text.StringBuilder sLinkCategory = new System.Text.StringBuilder();
            string[] SCategory = sCategory.Split(',');
            System.Data.DataTable dt = new System.Data.DataTable();
            dt.Columns.Add("sCategory");

            foreach (string element in SCategory)
            {
                dt.Rows.Add(element.ToString().Trim());
            }

            return dt;
        }
