c# 写的一个xml配置工具,自我感觉很强大(wpf)

使用递归获取xml所有节点,并把所有节点以树的形式展示,
//对应于节点来说一般都有注释,所以默认的xml节点上面的那个注释就和这个节点绑定到一起了,也可以没有
支持每个节点的增删改查,包括同时操作这个节点的注释,
不多说,奉上方法(其实只是供参考的,想了解xml的增删改查看这里)
 
这个是根据xml的路径获取xml文档,并且实例第一个根节点

#region 获取xml节点
/// <summary>
/// 获取xml节点
/// </summary>
/// <param name="url"></param>
public void GetXml(string url)
{
XmlDocument xmldoc = new XmlDocument();
try
{
xmldoc.Load(url);
}
catch (Exception e)
{
System.Windows.MessageBox.Show(e.Message);
return;
}

newurl = url;
//得到顶层节点列表
XmlNodeList topM = xmldoc.DocumentElement.ChildNodes;

//xml不为空
if (topM == null)
{
return;
}
XmlTv.Items.Clear();
//添加主节点
XmlNodeModel _XmlNodeModel = new XmlNodeModel();
_XmlNodeModel.NodeName = topM.Item(0).ParentNode.Name;
_XmlNodeModel.XmlNode = topM.Item(0).ParentNode;
TreeViewItem RootTvItem = CreateTvNode(_XmlNodeModel);
RootTvItem.IsExpanded = true;
XmlTv.Items.Add(RootTvItem);
//递归获取节点
GetNode(topM.Item(0), Guid.Empty, RootTvItem.Items);
}
#endregion

 
接下来就是关键的递归方法了,同时添加树,如果注意看会发现里面有一些费代码,嘿嘿

#region 递归获取节点
/// <summary>
/// 递归获取节点

/// <param name="_CommentNode">节点</param>
/// <param name="_PGuid">父guid</param>

private void GetNode(XmlNode _CommentNode, Guid _PGuid, ItemCollection _TvItem)
{
XmlNodeModel xmlModle = new XmlNodeModel();
XmlNode _Node = null;
if (_CommentNode.NodeType == XmlNodeType.Comment)
{
//注释
xmlModle.NodeComment = _CommentNode.Value;
xmlModle.CXmlNode = _CommentNode;
//获取注释下面的节点
_Node = _CommentNode.NextSibling;
if (_Node.NodeType == XmlNodeType.Comment)
{
XmlTv.Items.Clear();//清空xml树
System.Windows.Forms.MessageBox.Show("程序不允许两个或更多注释连续存在,请修改注释节点:" + _Node.Value);
return;
}
}
else
{
_Node = _CommentNode;

}
if (_Node == null)
{
return;
}
xmlModle.NodeGuid = Guid.NewGuid();
xmlModle.ParentNodeGuid = _PGuid;
xmlModle.NodeName = _Node.Name;
xmlModle.NodeItemList = new List<XmlItemModel>();
//节点项
if (_Node.Attributes != null)
{
foreach (XmlNode mainNode in _Node.Attributes)
{
XmlItemModel xmlItem = new XmlItemModel();
//key="123"
xmlItem.Key = mainNode.Name;//key
xmlItem.Value = mainNode.Value;//123
xmlModle.NodeItemList.Add(xmlItem);
}
}

xmlModle.IsChildNode = _Node.HasChildNodes;
xmlModle.XmlNode = _Node;
//添加到xml列表
CaCheCenter.XmlNodeModelList.Add(xmlModle);
//添加到树节点
TreeViewItem _TreeViewItem = CreateTvNode(xmlModle);
_TvItem.Add(_TreeViewItem);
//如果有子节点
if (_Node.HasChildNodes)
{
GetNode(_Node.ChildNodes.Item(0), xmlModle.NodeGuid, _TreeViewItem.Items);
}
//如果下个节点是空
if (_Node.NextSibling == null)
{
//隐藏选择按钮
SelectXmlBut.Visibility = Visibility.Collapsed;
return;
}
GetNode(_Node.NextSibling, _PGuid, _TvItem);
}

以上就把整棵树建好了,缺少的方法自己补全~!
添加方法(这个是添加节点的方法,不是节点里的属性,添加删除属性往下看)
