你去建两张表把这目录做成树的形式吧，这有个例子给你。
我把那树的结构写在xml中行不行？
行，你自己看着办。
靠，每次都是这样让我拿着那半成品在改，真是受不了。开始又不把它写成树的形式现在来让我改，无语。被这个纠结的项目整的郁闷死了。今天又提出新的需求了，领导要看到系统在线的人数，还要了解他们在用那些应用。citrix中也不知道有没有给出接口，研究了一上午得出的结论却不容乐观，citrix上给出的性能方面的数据却不是我想要的，杯具啊。
这是我建的一个xml的树形结构
<?xml version="1.0" encoding="utf-8" ?>
<Tree>
<parentNode name="父节点1" icon="~/images/dw.gif" url="flgl/ClassManager.aspx" target="iFrameInfo"></parentNode>
<parentNode name="父节点2" icon="~/images/dw.gif" url="flgl/Sec_class.aspx" target="iFrameInfo"></parentNode>
<parentNode name="父节点3" icon="~/images/dw.gif" url="AppIconList/AppIconList.aspx" target="iFrameInfo"></parentNode>
<parentNode name="父节点4" icon="~/images/dw.gif" url="">
<childNode name="子节点1" icon="~/images/dw.gif" url="ipgl/ServerAdressManager.aspx" target="iFrameInfo"></childNode>
<childNode name="子节点2" icon="~/images/dw.gif" url="ipgl/ZDCAdressManager.aspx" target="iFrameInfo"></childNode>
</parentNode>
<parentNode name="父节点5" icon="~/images/dw.gif" url="AppList.aspx" target="_parent"></parentNode>
</Tree>
我现在要做的是将他的结构写到树里去，下面是读取xml和将它添加到树中去。
//循环他的所有节点并添加到树中去
protected void CreateTree()
{
XmlDocument xmlDoc = new XmlDocument();
string xmlPath = AppDomain.CurrentDomain.BaseDirectory + "tree.xml";
xmlDoc.Load(xmlPath);
XmlNodeList nodeList = xmlDoc.SelectSingleNode("Tree").ChildNodes;
//XmlNodeList nodeList = xmlDoc.SelectNodes("@name[//parentNode]");
//TreeNode rootNode = new TreeNode("geng");
//TreeView1.Nodes.Add(rootNode);
try
{
TreeView1.Nodes.Clear();//清除树控件中所有节点
foreach (XmlNode xn in nodeList)
{
XmlElement xe = (XmlElement)xn;
string str = xe.GetAttribute("name");
string strIcon = xe.GetAttribute("icon");
string strUrl = xe.GetAttribute("url");
string strTarget = xe.GetAttribute("target");
TreeNode tn = new TreeNode(str);
tn.ImageUrl = strIcon;
if (!strUrl.Equals(""))
{
tn.NavigateUrl = strUrl;
}
tn.Target = strTarget;
TreeView1.Nodes.Add(tn);
XmlNodeList childNodeList = xn.ChildNodes;
foreach (XmlNode cxn in childNodeList)
{
XmlElement cxe = (XmlElement)cxn;
string str2 = cxe.GetAttribute("name");
string strUrl2 = cxe.GetAttribute("url");
string strTarget2 = cxe.GetAttribute("target");
TreeNode tnChild = new TreeNode(str2, str2);
if(!strUrl2.Equals(""))
{
tnChild.NavigateUrl = strUrl2;
}
tnChild.Target = strTarget2;
tn.ChildNodes.Add(tnChild);
}
}
TreeView1.CollapseAll();
}
catch
{
}
}
//用递归方法循环xml中的节点生成树
protected void CreateNewTree()
{
XmlDocument xmlDoc = new XmlDocument();
string xmlPath = AppDomain.CurrentDomain.BaseDirectory + "tree.xml";
xmlDoc.Load(xmlPath);
XmlNodeList nodeList = xmlDoc.SelectSingleNode("Tree").ChildNodes;
TreeView1.Nodes.Clear();//清除树控件中所有节点
try
{
foreach (XmlNode xn in nodeList)
{
XmlElement xe = (XmlElement)xn;
string str = xe.GetAttribute("name");
string strIcon = xe.GetAttribute("icon");
string strUrl = xe.GetAttribute("url");
string strTarget = xe.GetAttribute("target");
TreeNode tn = new TreeNode(str);
tn.ImageUrl = strIcon;
if (!strUrl.Equals(""))
{
tn.NavigateUrl = strUrl;
}
tn.Target = strTarget;
TreeView1.Nodes.Add(tn);
XmlNodeList childNodeList = xn.ChildNodes;
bianliAllNode(tn, childNodeList);
}
}
catch
{
}
TreeView1.CollapseAll();
}
//递归循环所有节点
private void bianliAllNode(TreeNode rtn, XmlNodeList nodeList)
{
try
{
foreach (XmlNode xn in nodeList)
{
XmlElement xe = (XmlElement)xn;
string str = xe.GetAttribute("name");
string strIcon = xe.GetAttribute("icon");
string strUrl = xe.GetAttribute("url");
string strTarget = xe.GetAttribute("target");
TreeNode tn = new TreeNode(str);
tn.ImageUrl = strIcon;
if (!strUrl.Equals(""))
{
tn.NavigateUrl = strUrl;
}
tn.Target = strTarget;
rtn.ChildNodes.Add(tn);
XmlNodeList childNodeList = xn.ChildNodes;
bianliAllNode(tn, childNodeList);
}
}
catch
{
}
}
