从配置文件xml中读取需要更新的表名

ArrayList al = new ArrayList();
try
{
XmlDocument xmlDoc = new XmlDocument();
string xmlPath = Application.StartupPath + "\\Config\\UpdateDataTable.xml";
XmlDocument xmlDoc1 = new XmlDocument();
xmlDoc.Load(xmlPath);

XmlNode rootNode = xmlDoc.SelectSingleNode("LoadTable");
XmlNodeList firstLevelNodeList = rootNode.ChildNodes;
foreach (XmlNode node in firstLevelNodeList)
{

XmlElement xe = (XmlElement)node;
if (xe.GetAttribute("Name").ToString() != " " && xe.GetAttribute("IsStart").ToString() == "是")
{
al.Add(xe.GetAttribute("Name").ToString());
}
}
}
catch
{
this.timer1.Enabled = false;
MessageBox.Show("读取配置文件出错！");
this.Dispose();
this.Close();
}
