我的观点陈述显示错误＆＃34;对于每个语句，不能对“公共定义”类型的变量进行操作“get enumerator＆＃39; ＆＃34; 我在模型和视图模型中定义了所有对象。我仍然得到这个错误。对此有何解决方案？
我的观点：
@using Edi.ViewModel
@model viewmodel
@{
<link rel="stylesheet" type="text/css" href="~/Content/style.css" />
Layout = null;
}

<table id="myTable">

-------------------@foreach (var items in Model)------------------------------
{
<tr onclick="javascript:showRow1(this);">

}
</table>
</div>
</form>
</body>
</html>
我的控制者：
namespace Edi.Controllers
{
public class HomeController :Controller
{
// GET: Home
public ActionResult Index()
{
mbill mt = new mbill();
billing db = new billing();
viewmodel vm = new viewmodel();
vm.Facility = db.Add1();
vm.EdiSendTo = db.Add2();
vm.InsQueue = db.Add3();
List<mbill> itemlist = new List<mbill>();
itemlist = db.Index();
return View("Index",vm);
}
}
}
我的模特：
public List<mbill> Index()
{
List<mbill> itemList = new List<mbill>();
connection();
SqlCommand cmd = new SqlCommand("procGetEDIBills", con);
cmd.CommandType = CommandType.StoredProcedure;
con.Open();
SqlDataAdapter sd = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
sd.Fill(dt);
mbill item = new mbill();
using (SqlDataReader sdr = cmd.ExecuteReader())
{
mbill io = new mbill();
while (sdr.Read())
{
io = new mbill();
io.visit = sdr["VisitDate"].ToString();
io.billno = sdr["Billno"].ToString();
io.Patient = sdr["PatientName"].ToString();
io.ProviderName = sdr["ProviderName"].ToString();
io.InsName = sdr["InsuranceName"].ToString();
io.PayBy = sdr["BillPayBy"].ToString();
io.InsCode = sdr["InsuranceId"].ToString();
io.User = sdr["QueueByUser"].ToString();
io.ClaimType = sdr["ClaimType"].ToString();
itemList.Add(io);
}
}
con.Close();
return itemList;
}
}
如果我在视图上删除@using Edi.ViewModel，@ model viewmodel，则foreach错误消失，dropdownlistfor shows不包含dropdownlistfor error的定义。
