【问题描述】:
我在 VIEW 中有模型数据,还有“其他”数据,它们不是模型的一部分。
当用户从 VIEW 中点击提交时,我希望模型数据也能通过?
我在控制器中的 HttpPost 如下所示:
[HttpPost]
public ActionResult RegisterSP(RegisterModel model, FormCollection collection)
{
System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
// Create Bytes using userName and Email to calculate CRC32
String s_user_id = SessionBag.Current.UserName + SessionBag.Current.Email;
Byte[] bytes_user_id = encoding.GetBytes(s_user_id);
UInt32 user_Id = Crc32.Compute(bytes_user_id);
但是,我在 VIEW 中还有其他数据,我也想将其发布到控制器,因此我添加了 FormCollection。
在调试时,我看到 RegisterModel 为空,但 FormCollection 包含来自模型和“其他”数据的所有数据。我可以只使用 FormCollection,但是我需要获取很多“其他”数据,并循环(使用 for 语句)formCollection,并获取特定类型字段的记录数。基本上,我有复选框,我需要循环遍历它们,它们都被称为,code1,code2,code3 ... code24 ...我需要获取所有带有“code*”的复选框并将它们插入数据库。如果我只有带有复选框的 FormCollection,我会很好,但我不能。有没有办法让我获得 FormCollection["code*"] 例如,所以使用通配符来获得我需要的所有(复选框)?还是我做错了所有这些事情
这是我的 VIEW(),
@model mvc1.Models.RegisterModel
@{
ViewBag.Title = "RegisterSP";
}

这是我的控制器,HTTPPOST 部分,我需要访问用户单击的 CheckBox 值
public ActionResult RegisterSP(RegisterModel model, FormCollection collection)
{
System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
// Create Bytes using userName and Email to calculate CRC32
String s_user_id = SessionBag.Current.UserName + SessionBag.Current.Email;
Byte[] bytes_user_id = encoding.GetBytes(s_user_id);
UInt32 user_Id = Crc32.Compute(bytes_user_id);
DBController dbcontroller = new DBController();
【问题讨论】:
-
您的原始控制器方法是什么样的,以及您的观点。您能否提供问题的简化版本?
-
好吧,现在,我只需要访问 FormCollection。目前,FormCollection 包含大约 50 个不同的字段,在这 50 个字段中,我需要访问 (24) 以下字段:code1、code2、code3 ..code24。我需要遍历这个列表并获取值。我可以使用通配符从 FormCollection 访问数据吗?最好的方法是什么?
-
我认为您需要阅读模型绑定。如果您提供当前视图和原始控制器操作,则更容易提供帮助
