I have a large project that is using AutoMapper (currently version 9)
I tried to update to V10 but my code falls over and I don't understand what I need to change to resolve it
I have multiple objects that use a base class , the objects inherit this base class for the common functions.
There are 3 main reason for this,
- All objects have a .ReadRecord method that allows me to instantiate the record and read the data from SQL,
- All objects have CreatedBy, CreateDate, AmendedBy, AmendedDate, and of course the ID properties
- All objects have an OriginalRecord property which is the same as the main record so I can compare what in the main record has changed so I only save those properties to the DB and update an Audit log
The process fails on the initial read where I populate the main object and the OriginalRecord property with itself
This works perfectly fine with V9 but not with v10
// Return the record for the specified ID
internal bool _ReadRecord<TENTITY>(int ID) where TENTITY : class, new()
{
_OriginalRecord = new TENTITY();
if (ID > 0)
{
TENTITY tmpRecord = BTPUtility.sqlDbAccessObject.ReadRecord<TENTITY>(ID);
if (tmpRecord != null)
{
var config = new AutoMapper.MapperConfiguration(cfg =>
{
cfg.AllowNullCollections = true;
cfg.CreateMap<TENTITY, TENTITY>();
});
var mapper = config.CreateMapper();
mapper.Map(tmpRecord, this);
_OriginalRecord = new TENTITY();
mapper.Map(tmpRecord, _OriginalRecord);
this.isRead = true;
return true;
}
}
return false;
}
The failure happens with mapper.Map(tmpRecord, _OriginalRecord);
yet the code used prior to the read is
vwQuoteHeader gridRecord = gvQuotes.GetRow(selectedRows[0]) as BTP.Business.Model.Quotes.vwQuoteHeader;
// Ensure the record type is the base record not the view
var config = new AutoMapper.MapperConfiguration(cfg =>
{
cfg.AllowNullCollections = true;
cfg.CreateMap<vwQuoteHeader, QuoteHeader>();
});
var mapper = config.CreateMapper();
mapper.Map(gridRecord, SelectedRecord);
SelectedRecord.ReadRecord();
Which works fine until it then actions the SelectedRecord.ReadRecord()
The error I get is
Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'The type arguments for method 'AutoMapper.IMapper.Map<TSource,TDestination>(TSource, System.Action<AutoMapper.IMappingOperationOptions<TSource,TDestination>>)' cannot be inferred from the usage. Try specifying the type arguments explicitly.'
I tried following the docs but couldn't understand what was wrong!
Any pointers would be appreciated
