使用适当的缩进C#将Treeview转换为XML [英] Treeview to XML with proper indentation c#

问题描述

我在将Treeview导出到带有正确缩进的Xml文件时遇到问题，我浏览了论坛，但找不到任何内容.

I'm having trouble exporting Treeview to a Xml file with proper indentation, I looked through the forum but could not find anything.

这里是有关如何将Xml写入Treeview的链接 递归，将具有属性的xml文件解析为treeview c#

Here is a link on how to write Xml to Treeview Recursion, parsing xml file with attributes into treeview c#

这是我的代码尝试将Treeview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

如您所见，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.

As you can see, the indentation is kinda off from my output, my purpose is to let user edit information on the tree nodes and save it back to the original file.

推荐答案

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标签

if you are going to use your code you need a variable to count how deep you are in recursion and use that number of tabs
