使用 LINQ 读取该 XML 文件
XDocument xdocument = XDocument.Load("Employees.xml");
IEnumerable<XElement> employees = xdocument.Root.Elements();
foreach (var employee in employees)
{
Console.WriteLine(employee);
}
访问单个元素
XElement xelement = XElement.Load("Employees.xml");
IEnumerable<XElement> employees = xelement.Root.Elements();
Console.WriteLine("List of all Employee Names :");
foreach (var employee in employees)
{
Console.WriteLine(employee.Element("Name").Value);
}
访问多个元素
XElement xelement = XElement.Load("Employees.xml");
IEnumerable<XElement> employees = xelement.Root.Elements();
Console.WriteLine("List of all Employee Names along with their ID:");
foreach (var employee in employees)
{
Console.WriteLine("{0} has Employee ID {1}",
employee.Element("Name").Value,
employee.Element("EmpId").Value);
}
访问具有特定属性的所有元素
XElement xelement = XElement.Load("Employees.xml");
var name = from nm in xelement.Root.Elements("Employee")
where (string)nm.Element("Sex") == "Female"
select nm;
Console.WriteLine("Details of Female Employees:");
foreach (XElement xEle in name)
Console.WriteLine(xEle);
访问具有特定属性的特定元素
XElement xelement = XElement.Load("..\\..\\Employees.xml");
var homePhone = from phoneno in xelement.Root.Elements("Employee")
where (string)phoneno.Element("Phone").Attribute("Type") == "Home"
select phoneno;
Console.WriteLine("List HomePhone Nos.");
foreach (XElement xEle in homePhone)
{
Console.WriteLine(xEle.Element("Phone").Value);
}
