编辑项目C＃的列表

Question

I wanna update a list of item in edit page, a user pass to edit page and update request for a list of question, a model for request is ready to use, edit.cshtml is like

@using (Html.BeginForm()){
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)
<fieldset>
    @foreach (var item in Model.Requesttables)
    {
        <div class="editor-label">
            @Html.LabelFor(modelItem => item.request)
        </div>
        <div class="editor-field">
            @Html.EditorFor(modelItem => item.request)
            @Html.ValidationMessageFor(modelItem => item.request)
        </div>
        <p>
            <input type="submit" value="Save" />
        </p>
    }
</fieldset>
}

how the controler will be??

public ActionResult Edit(List <Requesttable> requestlist)
    {//some logic here!}

Answer 1

If I understand it right, you want to see the controller. First I think that there is something wrong with your controller signature. It should be like this:

public ActionResult Edit(int id)
{
//search the object, no matter what it is - as long as it is form database by id
var db = new DbContext();
var yourRequestedList=db.Find(id); //or something like that, see linq for the correct sintax

yourRequestedList = objectThatWasEdited; 
}

I hope this helps you out, and don't forget to refactor. My cod is not a good practice, you do not instatiate the db inside of a controller method.
