C#解析Web Service返回的XML数据方法

using System.Xml;
// 假设 webServiceResult 是从 Web Service 获取的 XML 字符串
string webServiceResult = @"<Response>
<User>
<Id>123</Id>
<Name>张三</Name>
<Email>zhangsan@example.com</Email>
</User>
</Response>";
XmlDocument doc = new XmlDocument();
doc.LoadXml(webServiceResult);
XmlNode userNode = doc.SelectSingleNode("//User");
if (userNode != null)
{
string id = userNode["Id"]?.InnerText;
string name = userNode["Name"]?.InnerText;
string email = userNode["Email"]?.InnerText;
Console.WriteLine($"ID: {id}, Name: {name}, Email: {email}");
}

using System.Xml.Linq;
XDocument xDoc = XDocument.Parse(webServiceResult);
var user = xDoc.Descendants("User").FirstOrDefault();
if (user != null)
{
string id = user.Element("Id")?.Value;
string name = user.Element("Name")?.Value;
string email = user.Element("Email")?.Value;
Console.WriteLine($"ID: {id}, Name: {name}, Email: {email}");
}

XNamespace ns = "http://example.com/namespace";
var user = xDoc.Descendants(ns + "User").FirstOrDefault();
if (user != null)
{
string name = user.Element(ns + "Name")?.Value;
// 注意：每个元素都要加上命名空间
}

public class User
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Email { get; set; }
}
public class Response
{
public User User { get; set; }
}
// 反序列化
using (StringReader sr = new StringReader(webServiceResult))
{
XmlSerializer serializer = new XmlSerializer(typeof(Response));
Response response = (Response)serializer.Deserialize(sr);
Console.WriteLine($"{response.User.Name} - {response.User.Email}");
