object 与xml的转换读取

</pre><pre name="code" class="csharp"><pre name="code" class="csharp">

1.object ====> xml 
XmlDocument doc = new XmlDocument();
 XmlElement Root = doc.CreateElement("Table"); //主内容
 doc.AppendChild(Root);
List<string> eleColName=new List<string>();
List<string> eleValue=new List<string>();
//生成xml
 for (int k = 0; k < eleColName.Count; k++)
{
         XmlElement Child = doc.CreateElement(eleColName[i]);
          Child.InnerText = eleValue[k];
           Root.AppendChild(Child);
 }
if (doc.SerializeXml().IsNotNullAndEmpty())
 {
       string Xml = doc.SerializeXml().Substring(doc.SerializeXml().IndexOf('>') + 3);
}

2.xml =====>object
  System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
   string xml = bill != null ? bill.Xml : "";
   doc.LoadXml(xml);
   XmlNodeList xnl = doc.SelectSingleNode("Table").ChildNodes;
   foreach (XmlNode xn in xnl)
   {
       string name = xn.Name
       string value =  xn.InnerText                    
   }

3.实例更新xml(新增子节点或删除修改)

<pre name="code" class="csharp">xml:

<Template>

<Category text="备件库存导入列" key="KCNeedCKColumnNames">
  <Column>
   <Id>001</Id>
   <Key>sku</Key>
   <Value>
    <Name>物料编码</Name>
   </Value>
  </Column><pre name="code" class="csharp"></Category></Template>

</pre></div><pre>

/// <param name="key">类型</param>
/// <param name="id">修改列的编号</param>

/// <param name="names">别名</param>
