读出xml文件(从VSProject)

我需要从本地VS2013项目中读取xml文件。我已经可以访问我的文件，但不能访问xml-file-content，并且总是得到控制台输出:"空列表"。我找不到虫子了……:/

这是我的xml文件:

<SystemParameters>
  <Velocities>
    <Axis>
      <Name>V1</Name>
      <DefaultValue>v1</DefaultValue>
    </Axis>
    <Axis>
      <Name>V2</Name>
      <DefaultValue>v2</DefaultValue>
    </Axis>
    <Axis>
      <Name>V3</Name>
      <DefaultValue>v3</DefaultValue>
    </Axis>
  </Velocities>

  <Lengths>
    <Axis>
      <Name>L1</Name>
      <DefaultValue>l1</DefaultValue>
    </Axis>
    <Axis>
      <Name>L2</Name>
      <DefaultValue>l2</DefaultValue>
    </Axis>
    <Axis>
      <Name>L3</Name>
      <DefaultValue>l3</DefaultValue>
    </Axis>
  </Lengths>
</SystemParameters>

这是我的c#代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Xml;
using System.Xml.Linq;
using System.Reflection;
namespace Untitled
{
    public class Program
    {
        public static List<string> ReadoutVelocities(XElement parameters)
        {
            List<string> velocitiesList = new List<string>();
            var velocity = from s in parameters.Elements()
                            select s.Element("Velocities");
            foreach (var p in velocity.Elements("Axis"))
            {
                velocitiesList.Add(p.Element("Name").Value);
                velocitiesList.Add(p.Element("DefaultValue").Value);
            }
            return velocitiesList;
        }

        public static void Query(XElement parameters)
        {
            Console.WriteLine("Readout all velocity-parameters:'n");
            List<string> resultList = new List<string>();
            resultList = ReadoutVelocities(parameters);

            if(resultList.Count == 0)
                Console.WriteLine("Empty list");
            else
            {
                for (int i = 0; i < resultList.Count; i++)
                {
                    Console.WriteLine("Name: " + resultList.ElementAt(i));
                    Console.WriteLine("DefaultValue: " + resultList.ElementAt(i + 1) + "'n");
                }
                Console.WriteLine("'n- - - - - End-Of-Line- - - - - 'n");
            }
        }


        static void Main()
        {
            var asm = Assembly.GetExecutingAssembly();
            var textStream = asm.GetManifestResourceStream("Untitled.DefaultValues.xml");
            var xmlReader = new XmlTextReader(textStream);
            XElement parameters = XElement.Load(xmlReader);
            Query(parameters);
            Console.Read();
        }
    }
}
