9.集合和数组映射
在项目中,集合和数组使用的很多的,继续下来就讲讲他们的映射,很简单。
/// <summary>
/// 源对象
/// </summary>
public class Source
{
public int Value { get; set; }
public string Text { get; set; }
}
/// <summary>
/// 目标对象
/// </summary>
public class Destination
{
public int Value { get; set; }
public string Text { get; set; }
}
/// <summary>
/// 集合和数组映射测试类
/// </summary>
[TestClass]
public class ListAndArrayMaping
{
[TestMethod]
public void ListMapingTest()
{
//初始化映射 和单个对象的映射一样
Mapper.Initialize(cfg => cfg.CreateMap<Source, Destination>());
var srcList = new List<Source> {
new Source { Value = 5,Text="Five" }
};
//在这里指定类型参数,拿第一个为例;源类型:List<Source>;目标类型:IEnumerable<Destination>;
// List映射到IEnumerable;
IEnumerable<Destination> ienumerableDest1 = Mapper.Map<List<Source>, IEnumerable<Destination>>(srcList);
// List映射到ICollection;
ICollection<Destination> icollectionDest1 = Mapper.Map<List<Source>, ICollection<Destination>>(srcList);
// List映射到IList;
IList<Destination> ilistDest1 = Mapper.Map<List<Source>, IList<Destination>>(srcList);
// List映射到List;
List<Destination> listDest1 = Mapper.Map<List<Source>, List<Destination>>(srcList);
// List映射到Array;
Destination[] arrayDest1 = Mapper.Map<List<Source>, Destination[]>(srcList);
//验证List映射到IEnumerable的结果
foreach (var m in ienumerableDest1)
{
Assert.AreEqual("Five", m.Text);//通过
Assert.AreEqual(5, m.Value); //通过
}
//验证List映射到List结果
foreach (var m in listDest1)
{
Assert.AreEqual("Five", m.Text); //通过
Assert.AreEqual(5, m.Value); //通过
}
}
}
AutoMapper还支持以下集合类型的映射:
- IEnumerable
- IEnumerable
- ICollection
- ICollection
- IList
- IList
- List
- Arrays
以后在项目中使用起来就更加方便了!!!
