1.Add Mapster packages from NuGet
<package id="Mapster" version="7.3.0" targetFramework="net48" />
<package id="Mapster.Core" version="1.2.0" targetFramework="net48" />
2.Create Source class
//Source or DTO
public class TempCacheDto
{
public int Id { get; set; }
public string SerialNumber { get; set; }
}
3.Create Destination class
//Destination or Entity Db object
public class TempCache
{
public int Id { get; set; }
public string SerialNumber { get; set; }
}
4.Create Service or repository class where mapping required to convert Dto to Enity object.
Simple Save and Retrieve example below for using mapster and entity framework.
using Mapster;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace TempCache.Repositories
{
public class TempCacheRepository
{
//save data from dto model to entity using mapster
public bool Save(TempCacheModel bcTempCache)
{
using (var context = new DbContext())
{
if (bcTempCache.Id == 0)
{
TempCache entity = bcTempCache.Adapt<TempCache>();
context.TempCaches.Add(entity);
}
else
{
TempCache exist = context.TempCaches
.FirstOrDefault(x => x.Id == bcTempCache.Id);
if (exist != null)
{
exist = bcTempCache.Adapt<TempCacheModel, TempCache>(exist);
}
else
{
return false;
}
}
context.SaveChanges();
return true;
}
}
//get list from Db and retun as dto list using mapster
public List<TempCacheModel> TempCaches()
{
using (var context = new DbContext())
{
return context.TempCaches.ToList().Adapt<List<TempCacheModel>>();
}
}
//get list from Db and retun as dto list using mapster
public TempCacheModel GetById(int id)
{
using (var context = new DbContext())
{
return context.TempCaches.FirstOrDefault(x=>x.Id==slNo)?
.Adapt<TempCacheModel>();
}
}
}
}
