显示数组列表的值时没有输出

我写了一个c#代码，它显示了存储在arraylist中的值。

static void Main()
        {
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(@"C:''shreyas''NX_Temp''NX_Temp''000048_A''CompareReport3D.xml");

            XmlNodeList nodeList = xmlDoc.DocumentElement.SelectNodes("*");
            List<XmlNode> returnedmatchNode=TraverseXml(nodeList);
             for (int iIndex = 0; iIndex < returnedmatchNode.Count; iIndex++)
             {
                 Console.WriteLine("values" +returnedmatchNode[iIndex].Value);
             }
        }
        public static List<XmlNode> TraverseXml(XmlNodeList nodeList, int counter = 1)
        {
            List<XmlNode> matchNode = new List<XmlNode>();
            foreach (XmlNode node1 in nodeList)
            {
                if (node1.Attributes != null && node1.Attributes["match"] != null)
                {
                    matchNode.Add(node1.Attributes["match"]);
                }
                TraverseXml(node1.ChildNodes, counter);
            }
            Console.ReadLine();
            return matchNode;
        }

我正在尝试显示返回的匹配节点的值。但它不显示任何值。我无法找出代码中的错误。
