Strongly typed HTML template method and direct display model

Model:

public class article
{

[Display (name= "article")]
public string ArticleID {get; set;}

[Display (name= "category")]
public string CategoryID {get; set;}

[Display (name= "title")]
[Required]
[Stringlength (50)]
public string Title {get; set;}

[Display (name= "body")]
[DataType (Datatype.multilinetext)]
public string Content {get; set;}

[Display (Name = "Author")]
[Stringlength (20)]
public string AuthorName {get; set;}

[Display (Name = "date published")]
[DataType (Datatype.date)]
[DisplayFormat (dataformatstring= "{0:yyyy-mm-dd}", Applyformatineditmode=true)] only fit in view Html.dipspalyfor (a =>a.posttime) @Html. Edittorfor (a =>a.posttime)

Or the model uses @Html when traversing the ienumrable model for ienumrable<articles>. Dipspalyfor (ModelItem =>a.posttime) to truly reference the countless model,  appears as a date format. If you only use article in the view. Posttime does not reference data annotations, or displays time
[DisplayFormat (dataformatstring = "{0:yyyy-mm-dd HH:mm:ss}", Applyformatineditmode = True)]
[DataType (Datatype.datetime)]
[DisplayFormat (dataformatstring = "{0:yyyy-mm-dd HH:mm:ss}", Applyformatineditmode = True)]
Public DateTime posttime {get; set;}

[Display (name= "priority")]
[Range (1,100,errormessage= "{0} must be between {1} to {2}")]
public int Priororder {get; set;}

[Display (name= "traffic")]
public int Clickcount {get; set;}

Public virtual category category {get; set;}

Public article ()
{
This. ArticleID = Guid.NewGuid (). ToString ();
}

Controller:

Public ActionResult List (string categoryid,int? page)
{
if (string. IsNullOrEmpty (CategoryID))
return new Httpnotfoundresult ();

Viewbag.categoryname = _categoryservice.find (c =>c.categoryid = = CategoryID). CategoryName;
Viewbag.categoryid = CategoryID;

int pagenumber = page?? 1;
Viewbag.page = pagenumber;
int recordperpage = 20; Sets the number of records per page.
Viewbag.recordperpage = Recordperpage;

int totalrecord = 0; Defines an output parameter. In fact, the output parameter is assigned a value of 0, is not much significance. Just to be able to access this variable name. The output parameter, like the reference parameter, occupies the same memory space as the parameters, and the parameter values change, and the values of the output parameters are changed. The output parameter is to solve a problem where a function in C # can only return a single value, and use it to return multiple values.

var articlelist = _articleservice.findpagelisttwoorder<int,datetime> (PageNumber, RecordPerPage, out Totalrecord, a = A.categoryid = = Categoryid,ordertype.asc,a =>a.priororder,ordertype.desc, a = A.PostTime);
var artilelist = _articleservice.findall (). Where (A = = A.categoryid = = CategoryID). (a =>a.priororder). OrderByDescending (a =>a.posttime);

Viewbag.totalrecord = Totalrecord;
Viewbag.totalpage = (int) math.ceiling (double) Totalrecord/(double) recordperpage); Math.celling () takes the whole function up. Similarly, Math.floor () takes the entire function down.


Return View (Articlelist.tolist ());
}
