Project is also used in the usual three-tier architecture, and then the web side is MVC. All right, that's easy.

First, display the data list

Take the data, turn the DataTable into a list class, and put it in the viewbag.

         PublicActionResult Index () {List<Package.Model.Message> lists =NewList<package.model.message>(); Messagedal message=NewMessagedal (); DataSet DS= message. GetList ("1=1");  for(inti =0; I < DS. tables[0]. Rows.Count; i++) {lists. ADD (NewPackage.Model.Message () {gname= ds. tables[0]. rows[i]["Gname"]. ToString (), Gcontent= ds. tables[0]. rows[i]["gcontent"].            ToString ()}); }            //returns the data that needs to be boundViewbag.guestbooklist =lists; returnView (); }

The display on the index.cshtml page

    < Div >         @foreach (Package.Model.Message item in viewbag.guestbooklist)        {            <span >:</span>  @item. gcontent.tostring ()             <  />        }    </div>

Second, add data

1. First make a form on the index.cshtml page, prompt the action address, point to the Controller a class name

    <formID= "Formguestbook"Method= "POST"Action= "/index/add"><!--class name/method name -Name:<inputtype= "text"ID= "Txtname"name= "Txtname" /><BR/>content:<inputtype= "text"ID= "Txtcontent"name= "Txtcontent" /><BR/>        <inputtype= "Submit"name= "Btnsubmitguestbook"value= "Submit Message" />    </form>

2. Finally, after the request in the Controller page, add to the database, and then use the JS statement to return to the submission page

         PublicActionResult Add () {//Get form submission Data            stringGname = request.form["txtname"]; stringGcontent = request.form["txtcontent"]; //Insert DatabaseMessagedal message =NewMessagedal (); Message. ADD (NewPackage.Model.Message () {gname=Gname, Gcontent=gcontent}); //Back to List pageResponse.Write ("<script>alert (' message success! '); location.href= '/index ' </script>"); return NULL; }
