text templates c#

This is simple implementation of search/replace template engine in c#
Template class is following:

  
using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Collections; 
using System.Xml.Linq; 
using System.Linq; 
 
    public class Templates 
    { 
 
        private Hashtable templates; 
        public Templates(string templatesFilePath) 
        { 
 
            templates = new Hashtable(); 
            System.IO.StreamReader confFile = new System.IO.StreamReader(templatesFilePath); 
            XDocument configuration =XDocument.Parse(confFile.ReadToEnd()); 
            var tpls = from cs in configuration.Descendants("Template") 
                          select cs; 
            foreach (var t in tpls) 
            { 
                templates.Add(t.Attribute("Name").Value,t.Value); 
            } 
 
        } 
 
        /// <summary> 
        ///  REnder templates with  
        /// </summary> 
        /// <param name="templateName"></param> 
        /// <param name="values"></param> 
        /// <returns></returns> 
        public string Render(string templateName, params string[] values) 
        { 
            Hashtable hash = new Hashtable(); 
 
            for (int i = 0; i <= Math.Floor((decimal)values.Length/2); i+=2) 
            { 
                hash.Add(values[i], values[i + 1]); 
            } 
            return Render(templateName, hash); 
        } 
 
        /// <summary> 
        ///  Renders  
        /// </summary> 
        /// <param name="templateName"></param> 
        /// <param name="values"></param> 
        /// <returns></returns> 
        public string Render(string templateName,Hashtable values) 
        { 
            string result = String.Empty; 
            if (templates.ContainsKey(templateName)) 
            { 
                string template = (string)templates[templateName]; 
                foreach (DictionaryEntry entry in values) 
                { 
                    template = template.Replace("{$" + entry.Key + "}", "" + entry.Value); 
                } 
                result = template; 
            } else { 
 
            } 
            return result; 
        } 
 
    } 

Sample template file will be looking like this:

 
<Templates> 
<Template Name="template1"> 
	<![CDATA[ 
    My first template with {$Value1} 
    and  {$Value2} 
    ]]> 
	</Template> 
 
<Template Name="template2"> 
	<![CDATA[ 
        My second template with {$Value3} and {$Value4} 
    ]]> 
</Template> 
</Templates> 

And code for calling this awesome template engine will be following:

 
Templates templates = new Templates(ConfigManager.AssemblyDirectory + @"\MyTemplates.xml"); 
var result=templates.Render("template1", "Value1", Aome Value1, "Value2", DateTime.Now.ToString("yyyy-MM-ddThh:mm:ss")));
