ASP.NET MVC前台动态添加文本框并在后台使用FormCollection接收值_实用技巧_

 public class HomeController : Controller { public ActionResult Index() { return View(); } [HttpPost] public ActionResult Index(FormCollection collection) { var inputCount = 0; //前端文本框的数量 var inputValues = new List();//前端文本款的值放到这个集合 if (int.TryParse(collection["TextBoxCount"], out inputCount)) { for (int i = 1; i <= inputCount; i++) { if (!string.IsNullOrEmpty(collection["textbox" + i])) { inputValues.Add(collection["textbox" + i]); } } } TempData["InputResult"] = inputValues; return View(); } }

@{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml"; } 
 @if (TempData["InputResult"] != null) { 
 @foreach (var item in (List) TempData["InputResult"]) { 
@item
 } 
 } 
 @using (Html.BeginForm("Index", "Home", FormMethod.Post)) { 
 @Html.Hidden("TextBoxCount", 1) 
 } @section scripts {  }
