Code sample for: Update<T>(sourceObject, targetObject, string[] exceptions)

I want a generic update method which copies all properties of sourceObject to targ开发者_运维问答etObject but not methods mentioned in exceptions.

Have you tried using AutoMapper? It allows you to define custom mapping as well as auto mapping.

Example:

Given following types:

public class Type1
{
    public int MyProperty1 { get; set; }
    public int MyProperty2 { get; set; }
    public int MyProperty3 { get; set; }
    public int MyProperty4 { get; set; }
    public int MyProperty5 { get; set; }
}

public class Type2
{
    public int MyProperty1 { get; set; }
    public int MyProperty2 { get; set; }
    public int MyProperty3 { get; set; }
    public int MyProperty7 { get; set; }
    public int MyProperty8 { get; set; }
}

To create a map which ignores 2 properties (MyProperty7 & MyProperty8):

var map = Mapper.CreateMap<Type1, Type2>().
            ForMember(dest => dest.MyProperty7, opt => opt.Ignore()).
            ForMember(dest => dest.MyProperty8, opt => opt.Ignore());

Finally copy:

Type2 type2Variable = Mapper.Map<Type1, Type2>(type1Variable);

Mapping same types example:

var map = Mapper.CreateMap<Type1, Type1>().
            ForMember(dest => dest.MyProperty4, opt => opt.Ignore()).
            ForMember(dest => dest.MyProperty5, opt => opt.Ignore());

use:

Type1 anotherType1Variable = Mapper.Map<Type1, Type1>(type1Variable);
