Convert form elements to entity objects or collections-asp.net C #

Brief introduction:

Do webfrom development of the students know the background receive parameters very troublesome

Although the form can be converted directly to set in MVC, it does not support the collection of forms to list<t>

The use of a single object:

Form:

<input name= ' id '  value= ' 1 ' ><input name= ' sex '  value= ' man ' >

Background:

            // previous wording            New dlc_category ();             = request["sex"];             = Convert.ToInt32 (request["ID"]);             // now the wording            var category = Requesttomodel.getsingleform<dlc_category> ();

Use of Collection objects:

Form:

<input name= ' id '  value= ' 1 ' ><input name= ' sex '  value= ' male ' ><input name= ' id '  value= ' 2 ' > <input name= ' sex '  value= ' female ' ><input name= ' id '  value= ' 3 ' ><input name= ' sex '  value= ' women ' >

　　

Background:

  list<dlc_category> categorylists = requesttomodel.getlistbyform<dlc_category> ();
