我无法将Treeview导出到具有适当缩进的Xml文件，我查看了论坛但找不到任何内容。
这是一个关于如何将Xml写入Treeview的链接 Recursion, parsing xml file with attributes into treeview c#
以下是我的代码尝试将树视图导出为XML
public void exportToXml(TreeView tv, string filename)
{
sr = new StreamWriter(filename, false, System.Text.Encoding.UTF8);
//Write the header
sr.WriteLine("<?xml version=\"1.0\" encoding=\"utf-8\" ?>");
//Write our root node
sr.WriteLine("<" + treeView1.Nodes[0].Text + ">");
foreach (TreeNode node in tv.Nodes)
{
saveNode(node.Nodes);
}
//Close the root node
sr.WriteLine("</" + treeView1.Nodes[0].Text + ">");
sr.Close();
}
private void saveNode(TreeNodeCollection tnc)
{
foreach (TreeNode node in tnc)
{
//If we have child nodes, we'll write
//a parent node, then iterrate through
//the children
if (node.Nodes.Count > 0)
{
sr.WriteLine("\t\t<" + node.Text + ">");
saveNode(node.Nodes);
sr.WriteLine("\t\t</" + node.Text + ">");
}
else //No child nodes, so we just write the text
sr.WriteLine("\t\t\t"+node.Text);
}
}
Xml输出
<?xml version="1.0" encoding="utf-8" ?>

正如您所看到的，缩进与我的输出有点不同，我的目的是让用户编辑树节点上的信息并将其保存回原始文件。
答案 0 :(得分：0)
public void exportToXml(TreeView tv, string filename)
{
sr = new StreamWriter(filename, false, System.Text.Encoding.UTF8);
//Write the header
sr.WriteLine("<?xml version=\"1.0\" encoding=\"utf-8\" ?>");
//Write our root node
sr.WriteLine("<" + treeView1.Nodes[0].Text + ">");
foreach (TreeNode node in tv.Nodes)
{
int depth = 1;
saveNode(node.Nodes, depth);
}
//Close the root node
sr.WriteLine("</" + treeView1.Nodes[0].Text + ">");
sr.Close();
}
private void saveNode(TreeNodeCollection tnc, int depth)
{
foreach (TreeNode node in tnc)
{
for(int i =0; i<depth;i++)
{
sr.Write("\t");
}
if (node.Nodes.Count > 0)
{
sr.WriteLine("<" + node.Text + ">");
saveNode(node.Nodes, depth + 1);
for(int i =0; i<depth;i++)
{
sr.Write("\t");
}
sr.WriteLine("</" + node.Text.Split()[0] + ">");
}
else //No child nodes, so we just write the text
sr.WriteLine("<" + node.Text + "/>");
}
}
如果您要使用代码，则需要一个变量来计算递归的深度并使用该数量的选项卡
