c# - 在 C# 中从 XML 中读取多个值

Question

我有一个 xml 文件

<Actual-External-Terminals>
    <Actual-External-Terminal>
      <Party-Id value="EXTRA:77440" />
      <Name value="77440" />
      <Dial-String value="77440" />
      <IP-ISDN-SIP value="IP" />
      <Total-Connection-Time value="0s" />
      <Failing-Attempts value="0" />
      <Last-Failure-Cause value="N/A" />
      <List-of-Connection-Records>
        <Connection Call-Rate="768" Call-Type="Video" ConnectionTime="" Dialin-Dialout="Dial-in" Disconnection-Time="2012-02-16T13:33:32Z" Over-GW-port-limit="false" Over-MCU-port-limit="false" Reason-Disconnection="Normal" />
      </List-of-Connection-Records>
    </Actual-External-Terminal>

在上面的 xml 中，我想获取连接部分的所有值，请帮助我，谢谢不能使用 Linq to xml，因为它的 .net 框架 2.0 和桌面应用程序

System.Xml 是一种方式。如下：

  using System.Xml;
// Name space & class declarations...
static void ReadXml(string filePath)
        {
            //These would be kept in a settings file but constants for this example
            const string CONNECTION_LISTING_NODE_NAME = "List-of-Connection-Records";
            const string CONNECTION_NODE_NAME = "Connection";
            const string CALL_RATE_ATTRIBUTE_NAME = "Call-Rate";

            //Load xml
            var doc = new XmlDocument();
            doc.Load(filePath);
            var root = doc.FirstChild;
            var connectionRecordLists = doc.SelectNodes(String.Format("//{0}",CONNECTION_LISTING_NODE_NAME));
            if (connectionRecordLists == null) return;
            for (var i = 0; i < connectionRecordLists.Count; i++)
            {
                var connections = connectionRecordLists[i].SelectNodes(CONNECTION_NODE_NAME);
                if (connections == null) continue;
                for (var j = 0; j < connections.Count; j++)
                {
                    if (connections[j].Attributes != null
                        && connections[j].Attributes[CALL_RATE_ATTRIBUTE_NAME] != null)
                    {
                        Console.WriteLine(connections[j].Attributes[CALL_RATE_ATTRIBUTE_NAME].Value);
                    }

                }
            }
        }

如果您的 xml 文件具有固定的元素和属性，那么 XmlSerializer 类呢？http://msdn.microsoft.com/en-us/library/system.xml.serialization.xmlserializer(v=vs.80).aspx
