Adding a list of objects to SQL Server - ASP.NET Web API - asp.net

Question

I'm trying to add a list of objects to a SQL Server database via Entity Framework but I get an error with Add
[HttpPost]
public void Post(List<Row> rows)
{
try
{
using (DbModel dbModel = new DbModel())
{
foreach (var el in rows)
{
dbModel.Provider_Status.Add(el);
}
dbModel.SaveChanges();
}
}
catch { }
}
Row class:
public class Row
{
public string FileName { get; set; }
public string FileTitle { get; set; }
public string ProviderID { get; set; }
public string ServiceID { get; set; }
public string PublishDate { get; set; }
public string ExpiryDate { get; set; }
}
Database Model DbModel:
public partial class Provider_Status
{
public int Id { get; set; }
public string FileName { get; set; }
public string FileTitle { get; set; }
public string ProviderID { get; set; }
public string ServiceID { get; set; }
public string PublishDate { get; set; }
public string ExpiryDate { get; set; }
}
Error Message:
CS1503 Argument 1: cannot convert from 'File_Upload.Models.Row' to 'File_Upload.Models.Provider_Status

Answer 1

Your DbModel defines a data set of type Provider_Status - so if you want to add data to this data set, you need to provide Provider_Status objects - not Row objects (as you do now).
You need to convert those Row object to Provider_Status - try something like this:
[HttpPost]
public void Post(List<Row> rows)
{
try
{
using (DbModel dbModel = new DbModel())
{
foreach (var el in rows)
{
// create a new "Provider_Status" object, based on the
// "Row" values being passed in
Provider_Status status = new Provider_Status
{
FileName = el.FileName
FileTitle = el.FileTitle
ProviderID = el.ProviderID
ServiceID = el.ServiceID
PublishDate = el.PublishDate
ExpiryDate = el.ExpiryDate
};
// add that new Provider_Status object to your dbModel
dbModel.Provider_Status.Add(status);
}
dbModel.SaveChanges();
}
}
catch { }
}
