关于返回数组问题

Question

用xml 串行化吧，自己读取不麻烦吗

Answer 1

你现在想读取xml里面所有用户[]，密码[]？

Answer 2

普通的xml读取方法XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("XMLFile.xml");
XmlNode root = xmlDoc.SelectSingleNode("root");
int numberOfAccount = int.Parse(root.SelectSingleNode("IdNum").InnerText);
XmlNodeList nodes = root.SelectSingleNode("Account").ChildNodes;UserInfo[] users = new UserInfo[numberOfAccount];
for (int i = 0; i < numberOfAccount; i++)
{
    XmlNode elm = nodes[i];
    UserInfo user = new UserInfo(){ id = elm["id"].InnerText,password = elm["password"].InnerText };
    users[i] = user;
}class UserInfo
{
    public string id { get; set; }
    public string password { get; set; }
}

Answer 3

           string xml = @"<root>
                          <IdNum>2</IdNum>
                          <Account>
                            <user>
                        <id>sunzhenggo</id>
                        <password>123456</password>
                            </user>
                            <user>
                        <id>mengmeng</id>
                        <password>654321</password>
                            </user>
                          </Account>
                        </root>";
            
            XmlDocument xdoc1 = new XmlDocument();
            xdoc1.LoadXml(xml);
            XmlNodeList lists= xdoc1.SelectNodes("root/Account/user");            Dictionary<string, string> dictUsers = new Dictionary<string, string>();            foreach (XmlNode x in lists)
            {
                if (x!=null)
                {
                    string key = x.SelectSingleNode("id").InnerText;
                    string value = x.SelectSingleNode("password").InnerText;
                    dictUsers.Add(key, value);
                }
            }
