How to Avoid Duplicate Attribute Display When Parsing XML into a C# TreeView?

The method of analyzing the XML file contained in attributes in C# to the method of analysis of the attribute to the TreeView control

Question:

When using the Foreach cycle to parse the XML file containing attributes, the attributes will be displayed multiple times. How to modify the code to display only one attribute?

Solution:

Only display only one attribute in the TreeView control:

Explanation:

private void AddNode(XmlNode inXmlNode, TreeNode inTreeNode)
{
    if (inXmlNode.HasChildNodes)
    {
        // 检查 XmlNode 是否具有属性
        string attributes = "";
        foreach (XmlAttribute att in inXmlNode.Attributes)
        {
            attributes += " " + att.Name + ": " + att.Value;
        }
        if (!string.IsNullOrEmpty(attributes))
        {
            inTreeNode.Text += attributes;
        }


        foreach (XmlNode node in inXmlNode.ChildNodes)
        {
            TreeNode newNode = inTreeNode.Nodes.Add(node.Name);
            AddNode(node, newNode);
        }
    }
}

The updated code moves the attribute loop outside the sub -node cycle. This can ensure that even if there are multiple sub -nodes under the parent node, the attributes are only displayed once. The improved code uses the string variable

to accumulate all the attributes, and then add it to at one time to avoid repeatedly added.
