c# 遍历xml问题 - .NET技术 / C#

xml文件格式如下
XML code:

<?xml version="1.0" encoding="GB2312" ?>
<allproducts version="1.0">
<products>
<product name="prodId" value="28127" />
<product name="prodContent" value="5" />
<product name="prodPrice" value="5" />
</products>
<products>
<product name="prodId" value="10335" />
<product name="prodContent" value="5" />
<product name="prodPrice" value="4.95" />
</products>
<products>
<product name="prodId" value="28328" />
<product name="prodContent" value="5" />
<product name="prodPrice" value="5" />
</products>
</allproducts>




遍历代码如下
C# code:

XmlDocument xmldoc = new XmlDocument();
xmldoc.Load("E:\\1.xml");
XmlNodeList list2 = xmldoc.SelectSingleNode("/allproducts").ChildNodes;
XmlNodeList list = xmldoc.SelectSingleNode("/allproducts/products").ChildNo
