class Program
{
static void Main(string[] args)
{
var emp1 = new Soure.Employee();
emp1.TestEnum = Soure.MyEnum1.red;
var emp2 = new Soure.Employee();
emp2.TestEnum = Soure.MyEnum1.yellow;
var empList = new List<Soure.Employee>() { emp1, emp2 }.AsQueryable();
var mapExpr = Mapper.CreateMap<Soure.Employee, destination.Employee>();
Mapper.CreateMap<Soure.Department, destination.Department>();
Mapper.CreateMap<Soure.MyEnum1, destination.MyEnum2>();
Mapper.AssertConfigurationIsValid();
var mappedEmp = empList.Project().To<destination.Employee>();
}
}
我正在将Source.Employee映射到Destination.Employee。 所有属性都可以映射。 但是在枚举映射时,它会给我一个异常,无法将TestEnum映射到Int32。 如果使用override,则可以解决问题。
var mapExpr = Mapper.CreateMap<Soure.Employee, destination.Employee>()
.ForMember(x => x.TestEnum, opt => opt.MapFrom(s => (destination.MyEnum2)s.TestEnum));
那么它就可以工作了。
映射类如下所示:
namespace Soure
{
public class Employee
{
public int Id { get; set; }
public string Name { get; set; }
public Department dept { get; set; }
public int age { get; set; }
public MyEnum1 TestEnum { get; set; }
public Employee()
{
this.Id = 1;
this.Name = "Test Employee Name";
this.age = 10;
this.dept = new Department();
}
}
public class Department
{
public int Id { get; set; }
public string DeptName { get; set; }
Employee emp { get; set; }
public Department()
{
Id = 2;
DeptName = "Test Dept";
}
}
public enum MyEnum1
{
red,
yellow
}
}
namespace destination
{
public class Employee
{
public int Id { get; set; }
public string Name { get; set; }
public int age { get; set; }
public MyEnum2 TestEnum { get; set; }
public Department dept { get; set; }
}
public class Department
{
public int Id { get; set; }
public string DeptName { get; set; }
Employee emp { get; set; }
}
public enum MyEnum2
{
red,
yellow
}
}
