bootstrap adminlte教程11：打造内部邮件系统 -收件箱管理

收件箱是相当复杂的。功能多，就不一一介绍了，全用代码说明一切。

1.index 的方法

// GET: Emails
		public  ActionResult  Index(string emailState, string SearchString, int? page)
        {			
			///初始化分页
			if (!string.IsNullOrEmpty(emailState) && !string.IsNullOrEmpty(SearchString))
			{
				page = 1;
			}
			//赋值回传
			ViewBag.emailState = emailState;
			ViewBag.SearchString = SearchString;
			//默认情况下是只显示未阅读的。同时按creattime降序
			var emalilist = db.Emails.Where(c => c.EmailState == "0").OrderByDescending(z => z.CreatTime);
			//开始if进行分析
			if (!string.IsNullOrEmpty(emailState))     //这是不为空，表示点了已阅，需在搜索已阅
			{
				emalilist = db.Emails.Where(c => c.EmailState == "1").OrderByDescending(z => z.CreatTime);
				
			}
			 
				if (!string.IsNullOrEmpty(SearchString))  //表示有字段
				{
				 
				emalilist = db.Emails.Where(c => c.Title.Contains(SearchString)).OrderByDescending(z => z.CreatTime);
		     	}


			int pageNumber = page ?? 1;
			int pageSize =10;
			//通过ToPagedList扩展方法进行分页
			//IPagedList<CmsContent> pagedList = seachindex.ToPagedList(pageNumber, pageSize);


			return View(emalilist.ToPagedList(pageNumber, pageSize));



		}

　同时有一个批量删除的方法

 

//	批量删除文件功能

		public ActionResult DelEmails(FormCollection form)
		{
			//var cmscontents = db.CmsContents;
			//db.MenuRoles.RemoveRange(menuroles);
			var winnars = from x in form.AllKeys
						  where form[x] != "false"
						  select x;
			foreach (var id2 in winnars)

			{
				if (id2 != "selectAll")   //全选的那个不算数。那个checkbox值要去掉
				{
					var emailContents = db.Emails.Find(id2);
					if (emailContents != null)
					{
						db.Emails.Remove(emailContents);
					}
				}

			}

			db.SaveChanges();
			return RedirectToAction("index", "Emails");
		}

　　

　

2.视图

视图中加了分页。

 @model PagedList.IPagedList<jsdhh2.Models.Email>
@using PagedList.Mvc;
<link href="~/Content/PagedList.css" rel="stylesheet" />

@{
    ViewBag.Title = "Index";
} 
<div class="dhhheight1 col-md-12 col-xs-12"></div>
	<!--start 左 -->
<div class="col-md-3 hidden-xs">
	<div class="box box-solid">

</div>
