只是演示反射的用法，使用反射的方式性能不好，可以使用表达式树的方式做对象映射。查看Linq分类里有相关文章
Mapper：
public class Mapper
{
private static ConcurrentDictionary<Type, PropertyInfo[]> PROPTY_CACHE = new ConcurrentDictionary<Type, PropertyInfo[]>();
public static outT Map<inT, outT>(inT inObj) where outT : class
{
var inType = typeof(inT);
var outType = typeof(outT);
outT outObj = Activator.CreateInstance<outT>(); PropertyInfo[] outProperties = PROPTY_CACHE.GetOrAdd(outType, (k) =>
{
return outType.GetProperties();
});
PropertyInfo[] inProperties = PROPTY_CACHE.GetOrAdd(inType, (k) =>
{
return inType.GetProperties();
});
PropertyInfo inProp = null;
foreach (var outProp in outProperties)
{
if (inProperties.Select(p=>p.Name.Equals(outProp.Name,StringComparison.CurrentCultureIgnoreCase)).Any())
{
inProp = inProperties.FirstOrDefault(p => p.Name.Equals(outProp.Name, StringComparison.CurrentCultureIgnoreCase));
outProp.SetValue(outObj, inProp.GetValue(inObj));
}
}
return outObj; }
}
客户端：
People p = new People() { ID=,Name="fan", Xingbie = true,Birthday=DateTime.Now,Dog=new Pet() { Name="阿黄"} };
PeopleDTO pDTO = Mapper.Map<People, PeopleDTO>(p);
public class People
{
public int ID { get; set; }
public string Name { get; set; }
public bool Xingbie { get; set; }
public DateTime Birthday { get; set; }
public Pet Dog { get; set; }
}
public class PeopleDTO
{
public int ID { get; set; }
public string name { get; set; }
public DateTime Birthday { get; set; }
public Pet dog { get; set; }
}
public class Pet {
public string Name { get; set; }
}
