The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[DB_Payment.Models.GetInvoice]', but this dictionary requires a model item of type 'DB_Payment.Models.GetInvoice'. C# MVC

Question

Hi,
Getting an error in C# MVC application:

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[DB_Payment.Models.GetInvoice]', but this dictionary requires a model item of type 'DB_Payment.Models.GetInvoice'.

Controller:
List<DB_Payment.Models.GetInvoice> Items = new List<DB_Payment.Models.GetInvoice>();
DataSet ds = new DataSet();
ds = GetItems(customer_code);
if (ds.Tables[0].Rows.Count > 0)
{
foreach (DataRow dr in ds.Tables[0].Rows)
{
var chk = new GetInvoice();
chk.customer_code = dr["customer_code"].ToString();
chk.Date_Due = dr["Date_Due"].ToString();
chk.amount = dr["amount"].ToString();
chk.amt_paid = dr["amt_paid"].ToString();
Items.Add(chk);

            }  
        }  

        return View(Items);  

View Code:
@默 IEnumerable<DB_Payment.Models.GetInvoice>
@using GridMvc.Html
@using System.Web.Mvc.Ajax

@{

ViewBag.Title = "grid";  
WebGrid grid = new WebGrid(Model, rowsPerPage: 100);  
Layout = "~/Views/Shared/_Layout.cshtml";  

}

<div class="row">
<div class="col-lg-12">
<div class="card">
<div class="card-body">
<div class="row">
<div class="col-sm-6">
<h4 class="card-title mb-4">Inventory</h4>
</div>

            </div>  
            <div id="webgrid">  
                @Html.Grid(Model).Columns(columns =>  
                {  

                    columns.Add(m => m.customer_code).Titled("customer_code");                         
                    columns.Add(m => m.Date_Due).Titled("Date_Due");  
                    columns.Add(m => m.amount).Titled("Amount");  
                    columns.Add(m => m.amt_paid).Titled("Amt_Paid");  

                }  
                )  

            </div>  
        </div>  
    </div>  
</div>  

</div>

can somebody please help?

Hi @Vinisha ,
I have tested your codes and I can't reproduce your problems.
I think your codes you posted to us shouldn't have this error. This error means the value's type don't match. However, In the controller, you post the value type is a list. And in the view page, you used IEnumerable. It's right. So,which lines causes the error? Could you post other codes to us?
Best regards,
Yijing Sun

I am getting the same error with the following code

public ActionResult SpecificationOptions(string referenceNo,string requestID)
{
FDEDownload.Models.FDEDownloadIndividualContact specification;
FDEDownload.Models.FDEDownloadFireRatings fireRatings;
FDEDownload.Models.FDEDownloadBSENISO bSENISO;
FDEDownloadSiteLocations location;

        try  
        {  
            specification = new FDEDownload.Models.FDEDownloadIndividualContact();  
            fireRatings = new Models.FDEDownloadFireRatings();  
            bSENISO = new Models.FDEDownloadBSENISO();  
            location = new FDEDownloadSiteLocations();  

            ViewData["ReferenceNo"] = referenceNo;  
            ViewData["FDEDownloadRequestID"] = Convert.ToInt32(requestID);  
            string site = location.GetFDEDownloadSiteLocation();  
            ViewData["SiteLocation"] = site;  
            Session["FireRating"] = fireRatings.GetFDEDownloadFireRating();  
            Session["BSENISO"] = bSENISO.GetFDEDownloadBSENISO();  

            specification.FDEDownloadFireRatingList = fireRatings.GetFDEDownloadFireRating();  
            return View("~/Views/FDEDownload/SpecificationOptions.cshtml", specification);  
        }  
        catch (Exception ex)  
        {  
            ErrorLog.GetDefault(null).Log(new Error(ex));  
            throw;  
        }  
    }  

Then the specification view

@默 FDEDownload.Models.FDEDownloadIndividualContact
