C#读写XML

1、根据xml格式的string生成xml文件并保存到本地

 /// <summary>
 /// 保存XML到磁盘
 /// </summary>
 /// <param name="xml">xml格式的string</param>
 public void SaveDocXml(string xml, int objectID)
 {
     string path = "";
     string xmlName = "";
     try
     {
         XmlDocument xmlDoc = new XmlDocument();
         XmlDeclaration xmldecl = xmlDoc.CreateXmlDeclaration("1.0", "GBK", "");
         path = "E:\\Archives\\";
         xmlName = System.IO.Path.Combine(path, objectID.ToString() + ".xml");
         try
         {
             xmlDoc.LoadXml(xml);
         }
         catch (System.Exception ex)
         {
             logger.WriteExceptionLog(ex, "LoadXml Exception xml=" + xml);
         }
         try
         {
             xmlDoc.Save(xmlName);
         }
         catch (System.Exception ex)
         {
             logger.WriteExceptionLog(ex, "Save Exception xml=" + xmlDoc.ToString());
         }
     }
     catch (System.Exception ex)
     {
         logger.WriteExceptionLog(ex, "SaveDocXml Exception: " + "xmlName=" + xmlName);
     }
 }
