c# - 从 XML 标签获取内文？

Question

我正在尝试使用 XML 标记的内部文本或值填充数组。我可以遍历标签的节点，我只是在提取存储值时遇到问题。

我正在循环问题底部的属性标记的子节点 XML。

    XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("C://Users//Shaun//Documents//Visual Studio 2010//Projects//LightStoneTestService//LightStoneTestService//FileTest//Testdo.xml");

//XmlNodeList dataNodes = xmlDoc.SelectNodes("//Properties");
XmlNodeList oXMlNodeList = xmlDoc.GetElementsByTagName("Properties");

for (int Count = 0; Count < 27; Count++)
{
    foreach (XmlNode node in oXMlNodeList)
    {                    
        int Max = node.ChildNodes.Count;                   
        foreach (XmlNode childNode in node.ChildNodes) //For each child node in FieldData
        {                          
              if (ArrayProperties[Count].LightStoneTag == childNode.Name)
            {
              ArrayProperties[Count].Value = node.SelectSingleNode(ArrayProperties[Count].LightStoneTag).InnerText;    
            }                                                     
        }
    }
}

** * **我的 Xml 文件如下所示：

这是命名空间问题。for在循环之前添加这部分代码：

        NameTable nt = new NameTable();
        nt.Add("Properties");
        XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt);
        nsmgr.AddNamespace("ns1", "Properties");

将检索到的行更改InnerText为：

        ArrayProperties[Count].Value = node
            .SelectSingleNode(
                String.Concat("//ns1:", ArrayProperties[Count].LightStoneTag), 
                nsmgr)
            .InnerText;
