在这里,我在 MVC 中使用 WCf 服务并从该服务中检索值并尝试在视图中显示它。得到错误:
传递到字典中的模型项的类型为“System.Collections.Generic.List”,但此字典需要“System.Collections.Generic.IEnumerable”类型的模型项
服务代码:
public IList<AddressDetails> GetAddressDetails(string addressid)
{
List<AddressDetails> addressdetails = new List<AddressDetails>();
{
con.Open();
SqlCommand cmd = new SqlCommand("select Name,EmailAddress,Line1,City from Address where addressid ='6742596A-F413-4C71-8BAB-0016F96B56A0'", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
if (dt.Rows.Count > 0)
{
for (int i = 0; i < dt.Rows.Count; i++)
{
AddressDetails addressInfo = new AddressDetails();
//addressInfo.Addressid = dt.Rows[i]["Addressid"].ToString();
addressInfo.Name = dt.Rows[i]["Name"].ToString();
addressInfo.EmailAddress = dt.Rows[i]["EmailAddress"].ToString();
addressInfo.Line1 = dt.Rows[i]["Line1"].ToString();
addressInfo.City = dt.Rows[i]["City"].ToString();
addressdetails.Add(addressInfo);
}
}
con.Close();
}
return addressdetails;
}
控制器代码:
ServiceReference1.Service1Client objService = new ServiceReference1.Service1Client();
public ActionResult sample()
{
IList<AddressDetails> objAddressDetails = new List<AddressDetails>();
objAddressDetails = objService.GetAddressDetails("");
return View(objAddressDetails.ToList());
}
查看代码:
@model IEnumerable<Magelia.WebStore.StarterSite.Web.Models.Sample.SampleViewModel>
@{
ViewBag.Title = "sample";
}
<h2>sample</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<table>
<tr>
<th>
AddressId
</th>
<th>
Name
</th>
<th>
EmailAddress
</th>
<th>
Line1
</th>
<th>
City
</th>
<th></th>
</tr>
@foreach (var item in Model) {
<tr>
<td>
@Html.DisplayFor(modelItem => item.AddressId)
</td>
<td>
@Html.DisplayFor(modelItem => item.Name)
</td>
<td>
@Html.DisplayFor(modelItem => item.EmailAddress)
</td>
<td>
@Html.DisplayFor(modelItem => item.Line1)
</td>
<td>
@Html.DisplayFor(modelItem => item.City)
</td>
<td>
@Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
@Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
@Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
</td>
</tr>
}
</table>
有什么建议吗?
