MVC创建XML,并实现增删改
如果创建如下的XML：
<?xml version="1.0" encoding="utf-8" standalone="yes"?><Students> <Student Id="1"> <Name>darren</Name> </Student></Students>
创建XML文件
在HomeController中，在根目录下创建new.xml文件：
public ActionResult Index() { return View(); } [HttpPost] public ActionResult AddXml() { string path = Server.MapPath("~/new.xml"); XDocument doc = new XDocument( new XDeclaration("1.0","utf-8","yes"), new XElement("Students",new XElement("Student", new XAttribute("Id","1"), new XElement("Name","darren") )) ); doc.Save(path); return Json(new {msg = true}, JsonRequestBehavior.AllowGet); }
在Index.cshtml中通过异步请求：
@model IEnumerable<MvcApplication1.Models.Student>@{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml";}<h2>Index</h2><input type="button" value=http://www.mamicode.com/"创建XML" id="create"/>@section scripts{ <script type="text/javascript"> $(function() { $(‘#create‘).on(‘click‘, function() { $.ajax({ url: ‘@Url.Action("AddXml", "Home")‘, dataType: ‘json‘, data: {}, type: ‘POST‘, success: function(data) { if (data.msg) { alert(‘创建成功‘); } } }); }); }); </script>}
显示XML文件元素
修改HomeController中的Index方法为：
public ActionResult Index() { string path = Server.MapPath("~/new.xml"); List<Student> result = new List<Student>(); var nodes = ReadXML(path).Descendants("Student"); foreach (var node in nodes) { Student student = new Student(); student.Id = Convert.ToInt32(node.Attribute("Id").Value); foreach (var ele in node.Elements()) { student.Name = ele.Value; } result.Add(student); } return View(result); } private XDocument ReadXML(string path) { XDocument xDoc = new XDocument(); xDoc = XDocument.Load(path); return xDoc; }
修改Home/Index.cshtml为：
@model IEnumerable<MvcApplication1.Models.Student>@{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml";}<h2>Index</h2><input type="button" value=http://www.mamicode.com/"创建XML" id="create"/><table> <tr> <th>编号</th> <th>姓名</th> </tr> @foreach (var item in Model) { <tr> <td>@item.Id</td> <td>@item.Name</td> <td>@Html.ActionLink("修改","Update","Home",new {id= item.Id},null)</td> <td>@Html.ActionLink("删除","Delete","Home", new {id = item.Id},null)</td> </tr> }</table><br/>@Html.ActionLink("创建","Create","Home")@section scripts{ <script type="text/javascript"> $(function() { $(‘#create‘).on(‘click‘, function() { $.ajax({ url: ‘@Url.Action("AddXml", "Home")‘, dataType: ‘json‘, data: {}, type: ‘POST‘, success: function(data) { if (data.msg) { alert(‘创建成功‘); } } }); }); }); </script>}
添加元素到XML文件中
HomeController中：
public ActionResult Create() { return View(); } [HttpPost] public ActionResult Create(Student student) { string path = Server.MapPath("~/new.xml"); XDocument xd = XDocument.Load(path); XElement newStudent = new XElement("Student", new XAttribute("Id", student.Id), new XElement("Name",student.Name)); xd.Root.Add(newStudent); xd.Save(path); return RedirectToAction("Index"); }
Home/Create.csthml中：
@model MvcApplication1.Models.Student@{ ViewBag.Title = "Create"; Layout = "~/Views/Shared/_Layout.cshtml";}<h2>Create</h2>@using (Html.BeginForm("Create", "Home", FormMethod.Post, new {id = "addForm"})){ @Html.LabelFor(m => m.Id) @Html.EditorFor(m => m.Id) <br/> @Html.LabelFor(m => m.Name) @Html.EditorFor(m => m.Name) <br/> <input type="submit" value=http://www.mamicode.com/"创建"/>}
修改XML文件中的元素
HomeController中：
public ActionResult Update(string id) { string path = Server.MapPath("~/new.xml"); XElement xe = XElement.Load(path); var studentXe = xe.Elements("Student").Where(e => e.Attribute("Id").Value =http://www.mamicode.com/= id).FirstOrDefault(); Student student = new Student(); student.Id = Convert.ToInt32(studentXe.Attribute("Id").Value); student.Name = studentXe.Element("Name").Value; return View(student); } [HttpPost] public ActionResult Update(Student student) { string path = Server.MapPath("~/new.xml"); var studentId = student.Id.ToString(); XDocument xd = XDocument.Load(path); XElement node = xd.Root.Elements("Student").Where(e => e.Attribute("Id").Value =http://www.mamicode.com/= studentId).FirstOrDefault(); node.SetElementValue("Name", student.Name); xd.Save(path); return RedirectToAction("Index"); }
Home/Update.csthml中：
@model MvcApplication1.Models.Student@{ ViewBag.Title = "Update"; Layout = "~/Views/Shared/_Layout.cshtml";}<h2>Update</h2>@using (Html.BeginForm("Update", "Home", FormMethod.Post, new {id = "editForm"})){ @Html.HiddenFor(m => m.Id) @Html.LabelFor(m => m.Name) @Html.EditorFor(m => m.Name) <br/> <input type="submit" value=http://www.mamicode.com/"修改"/>}
删除XML文件中的元素
HomeController中：
public ActionResult Delete(string id) { string path = Server.MapPath("~/new.xml"); XElement xe = XElement.Load(path); var studentXe = xe.Elements("Student").Where(e => e.Attribute("Id").Value =http://www.mamicode.com/= id).FirstOrDefault(); Student student = new Student(); student.Id = Convert.ToInt32(studentXe.Attribute("Id").Value); student.Name = studentXe.Element("Name").Value; return View(student); } [HttpPost] public ActionResult Delete(Student student) { string path = Server.MapPath("~/new.xml"); var studentId = student.Id.ToString(); XDocument xd = XDocument.Load(path); xd.Root.Elements("Student").Where(e => e.Attribute("Id").Value =http://www.mamicode.com/= studentId).Remove(); xd.Save(path); return RedirectToAction("Index"); }
Home/Delete.cshtml中：
@model MvcApplication1.Models.Student@{ ViewBag.Title = "Delete"; Layout = "~/Views/Shared/_Layout.cshtml";}<h2>Delete</h2>@Model.Id<br/>@Model.Name<br/>@using (Html.BeginForm("Delete", "Home", FormMethod.Post, new {id = "delForm"})){ @Html.HiddenFor(m => m.Id) <input type="submit" value=http://www.mamicode.com/"删除"/>}
