i have entity class, pinjaman_DataEntities
, that has 4 properties.
public string appl_no { get; set; }
public string reff_number { get; set; }
public string cust_name { get; set; }
public string merchant_id { get; set; }
and i have a database context gt_applikasi_pinjaman
that has more properties than pinjaman_DataEntities
, but still have same name of 4 properties above.
and i want to map from pinjaman_DataEntities
to gt_appllikasi_pinjaman
and this codes below :
public bool updateFilter(pinjaman_DataEntities filterPinjaman)
{
bool valid = true;
filterPinjaman = (pinjaman_DataEntities)ConvertDataEmpetyStringToNull(filterPinjaman);
gt_applikasi_pinjaman pinjaman = dbContext.gt_applikasi_pinjaman.Find(filterPinjaman.appl_no);
Mapper.CreateMap<pinjaman_DataEntities, gt_applikasi_pinjaman>()
.ForAllMembers(opt => opt.Condition(srs => !srs.IsSourceValueNull));
Mapper.Map(filterPinjaman, pinjaman);
dbContext.Entry(pinjaman).State = EntityState.Modified;
dbContext.SaveChanges();
return valid;
}
after i run the code, i have error when the code was on
Mapper.Map(filterPinjaman, pinjaman);
And the error message is :
An exception of type 'System.Exception' occurred in WebApplicationServiceAPIA.dll but was not handled in user code
Additional information:
Mapping types:
pinjaman_DataEntities -> Nullable`1
ServiceAPIA.DataEntities.pinjaman_DataEntities -> System.Nullable`1[[System.DateTime, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]
Destination path: gt_applikasi_pinjaman.appl_date.appl_date
Source value: ServiceAPIA.DataEntities.pinjaman_DataEntities
What's that mean, and how to fix it? Lot of thanks.
I am using auto mapper 6.2.2.0 latest release. and in this version to skip the null you need to use -
.ForAllMembers(opt => opt.Condition(src => src != null))
check the below code if it works for you.. Fiddle
using System;
using AutoMapper;
public class Program
{
public static void Main(string[] args)
{
var sVm = new SourceVM
{
cust_name = "Gaurav",
appl_no = "HR99TEMP5253"
};
var r = MyConvert(sVm);
Console.WriteLine(r.cust_name);
Console.WriteLine(r.appl_no);
Console.WriteLine(r.appl_date);
r = MyConvert(null);
Console.WriteLine(r.cust_name);
Console.WriteLine(r.appl_no);
Console.WriteLine(r.appl_date);
}
private static DestinationVM GetDest()
{
return new DestinationVM
{
cust_name = "Deepak",
appl_no = "HR26DK6149",
appl_date = DateTime.Now
};
}
public static DestinationVM MyConvert(SourceVM vm)
{
DestinationVM destVm = GetDest();
var config = new MapperConfiguration(cfg =>
{
cfg.CreateMap<SourceVM, DestinationVM>()
.ForAllMembers(opt => opt.Condition(src => src != null));
});
config.CreateMapper().Map(vm, destVm);
return destVm;
}
}
public class SourceVM
{
public string appl_no { get; set; }
public string reff_number { get; set; }
public string cust_name { get; set; }
public string merchant_id { get; set; }
}
public class DestinationVM
{
public string appl_no { get; set; }
public string reff_number { get; set; }
public string cust_name { get; set; }
public string merchant_id { get; set; }
public Nullable<System.DateTime> appl_date { get; set; }
}
