Asp.Net Mvc+MongoDB简单增删查改
概要:现在很多企业都在使用非关系型的NoSql数据库,其中MongoDB是相当热门的,最近有空就研究了一下,本文写了一套基于Asp.Net Mvc和MongoDB的简单增删查改,本文部分内容是借用其他博文,最后我会贴出出处.
正文:
在控制器的Models中新建一个UserModel模型(其中相当于另开一个类库,类似Dal层)
using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace MvcApplication1.Models.Home { using Model; using MongoDB; public class UserModel { //链接字符串(此处三个字段值根据需要可为读配置文件) public string connectionString = "Server=127.0.0.1:27017"; //数据库名 public string databaseName = "DataBase_YZR"; //集合名 public string collectionName = "UserInfo"; private Mongo mongo; private MongoDatabase mongoDatabase; private MongoCollection<Document> mongoCollection; public UserModel() { mongo = new Mongo(connectionString); mongoDatabase = mongo.GetDatabase(databaseName) as MongoDatabase; mongoCollection = mongoDatabase.GetCollection<Document>(collectionName) as MongoCollection<Document>; mongo.Connect(); } ~UserModel() { mongo.Disconnect(); } /// <summary> /// 增加一条用户记录 /// </summary> /// <param name="doc"></param> public void Add(Document doc) { mongoCollection.Insert(doc); } /// <summary> /// 删除一条用户记录 /// </summary> public void Delete(string Name) { mongoCollection.Remove(new Document { { "Name", Name } }); } /// <summary> /// 更新一条用户记录 /// </summary> /// <param name="doc"></param> public void Update(Document doc) { mongoCollection.FindAndModify(doc, new Document { { "Name", doc["Name"].ToString() } }); } /// <summary> /// 查找所有用户记录 /// </summary> /// <returns></returns> public IEnumerable<Document> FindAll() { return mongoCollection.Find(c=>true).Documents; } } }
这里封装了一些的基本的增删查改操作,以及连接,数据库对象的创建等.
Note:详细看过的你会发现,UserInfo是基于Name作为主键,这里只是作为演示demo,具体业务需要具体做一些改变.
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Model { public class UserInfo { private string name; public string Name { get { return name; } set { name = value; } } private int age; public int Age { get { return age; } set { age = value; } } } }
控制器内容:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; namespace MvcApplication1.Controllers { using MongoDB; using MvcApplication1.Models.Home; using Model; using System.Text;
public class IndexController : Controller { // // BY YZR UserModel userModel = new UserModel(); public ActionResult Index() { return View(); } /// <summary> /// 获取全部用户列表，通过json将数据提供给jqGrid /// </summary> public JsonResult UserList() { string rows=Request["rows"]; string page=Request["page"]; var list = userModel.FindAll(); int i = 0; var query = from u in list select new { id = i++, Name=u["Name"].ToString(), Age=u["Age"].ToString() }; var data = new { total = query.Count() / Convert.ToInt32(rows) + 1, page = Convert.ToInt32(page), records = query.Count(), rows = query.Skip(Convert.ToInt32(rows) * (Convert.ToInt32(page) - 1)).Take(Convert.ToInt32(rows)) }; return Json(data, JsonRequestBehavior.AllowGet); } /// <summary> /// 响应Js的“Add”ajax请求，执行添加用户操作 /// </summary> public ActionResult Add() { StringBuilder sb = new StringBuilder(); string paramsdata=Request["data"]; string[] ss=paramsdata.Split(‘&‘); string name = ss[0]; name=name.Split(‘=‘)[1]; string age = ss[1]; age = age.Split(‘=‘)[1]; Document doc = new Document(); doc["Name"] = name; doc["Age"] = age; try { userModel.Add(doc); return Content("添加成功"); } catch { return Content("添加失败"); } } /// <summary> /// 响应Js的“Update”ajax请求，执行更新用户操作 /// </summary> public ContentResult Update() { //修改年龄 StringBuilder sb = new StringBuilder(); string paramsdata = Request["data"]; string[] ss = paramsdata.Split(‘&‘); string name = ss[0]; name = name.Split(‘=‘)[1]; string age = ss[1]; age = age.Split(‘=‘)[1]; Document doc = new Document(); doc["Name"] = name; doc["Age"] = age; try { userModel.Update(doc); return Content("修改成功"); } catch { return Content("修改失败"); } } /// <summary> /// 响应Js的“Delete”ajax请求，执行删除用户操作 /// </summary> public ContentResult Delete() { string name=Request["id"]; string[] names=name.Split(‘,‘); for (int i = 0; i < names.Length; i++) { try { userModel.Delete(names[i]); } catch { return Content("删除失败"); } } return Content("删除成功"); } } }

// easyui datagrid dateFormatter function formatterdate(val, row) { if (val != null) { var date = new Date(val); return date.getFullYear() + ‘-‘ + (date.getMonth() + 1) + ‘-‘ + date.getDate(); } } function delete_dg() { var selected = $("#tab").datagrid(‘getSelected‘); if (selected != null) { $.messager.confirm(‘提示‘, ‘是否确定要删除？‘, function (yes) { if (yes) { var ids = ""; var checked = $("#tab").datagrid(‘getChecked‘); $.each(checked, function (i, row) { ids += row.Name + ","; }) ids = ids.substring(0, ids.length - 1); $.post("/Index/Delete", { "action": "del", id: ids }, function (data) { $.messager.alert(‘提示‘, data); $("#tab").datagrid(‘reload‘); }); } }) } else { $.messager.alert(‘提示‘, ‘您还没有选中一行数，请选中在删除！‘); } } function add_dg() { //表单清空 $("#fm_dg")[0].reset(); //显示 $("#dd_dg").show(); //以窗体的形式展示 $("#dd_dg").dialog({ title: "添加EMP信息",//标题 iconCls: "icon-add",//图标 width: 600,//窗体的宽度 height: 400,//窗体的高度 modal: true, //遮罩层 //按钮集合 buttons: [ { text: "添加",//添加按钮的文本值 iconCls: "icon-ok", //添加按钮的图标 handler: function () { //将数据序列化 var parm = $("#fm_dg").serialize(); //中文格式转换 var pp = decodeURIComponent(parm, true); //post异步提交 $.post("/Index/Add", { "action": "add", data: pp }, function (data) { $.messager.alert(‘提示‘, data); //重新加载datagrid $("#tab").datagrid(‘reload‘); //关闭 $("#dd_dg").window(‘close‘); }); } }, { text: "取消", iconCls: "icon-cancel", handler: function () { $("#dd_dg").window("close"); } } ] }); } function edit_dg() { //选中一行，获取这一行的属性的值 var selected = $("#tab").datagrid(‘getSelected‘); //判断是否选中 if (selected != null) { //$("#id").val(selected.JSON_id); $("#id").val(selected.id); $("#Name").val(selected.Name); $("#Age").val(selected.Age); //取值显示性别 //if (selected.JSON_sex == "男") { // $("#sex option").eq(0).attr("selected", "selected"); //} else { // $("#sex option").eq(1).attr("selected", "selected"); //} $("#dd_dg").show(); //显示修改窗体 $("#dd_dg").dialog({ title: "编辑信息", iconCls: "icon-edit", modal: true,//遮罩层 width: 600, height: 400, buttons: [ { text: "编辑", iconCls: "icon-edit", handler: function () { var parm = $("#fm_dg").serialize(); var pp = decodeURIComponent(parm, true); $.post("/Index/Update", { "action": "edit", data: pp }, function (data) { $.messager.show({ title: "提示", msg: data }); $("#tab").datagrid("reload"); $("#dd_dg").window("close"); }); } }, { text: "取消", iconCls: "icon-cancel", handler: function () { $("#dd_dg").window(‘close‘); } } ] }); } else { $.messager.alert(‘提示‘, ‘请选中一行在进行编辑‘); } }
