示例 XML 檔案

    <Sample>
    <Account>
        <One number="12"/>
        <Two number="14"/>
    </Account>
    <Account>

從這個 XML 檔案中讀取:

    using System.Xml;
    using System.Collections.Generic;
    
    public static void Main(string fullpath)
    {
        var xmldoc = new XmlDocument();
        xmldoc.Load(fullpath);
        
        var oneValues = new List<string>();
        
        // Getting all XML nodes with the tag name
        var accountNodes = xmldoc.GetElementsByTagName("Account");
        for (var i = 0; i < accountNodes.Count; i++)
        {
            // Use Xpath to find a node
            var account = accountNodes[i].SelectSingleNode("./One");
            if (account != null && account.Attributes != null)
            {
                // Read node attribute
                oneValues.Add(account.Attributes["number"].Value);
            }
        }
}
