上一篇 介绍了OO Mapper的作用以及支持的功能。这一篇将以上一篇为提纲进行实践。
准备工作:
实践:
1. Any -> String
Assert.AreEqual("5", Mapper.Map<int, string>(5));
2. primitive->Enum,Enum->primitive
[TestFixture] public class EnumTests { public enum En1 : byte { a = 1, b = 2, c = 3 } public enum En2 : long { a = 1, b = 2, c = 3 } public enum En3 : int { b = 2, c = 3, a = 1 } public class A { public En1 en1 { get; set; } public En2 en2; public En3 en3 { get; set; } public decimal en4; public string en5; public En1? en6; public En3 en7; public En3? en8; public En3? en9 = En3.c; } public class B { public decimal en1 = 3; public En1 en2 { get; set; } public string en3 = "c"; public En2 en4 = En2.b; public En3 en5 = En3.a; public En2 en6 = En2.c; public En1? en7 = En1.c; public En1? en8 = En1.c; public En2? en9 = null; public B() { en2 = En1.c; } } [Test] public void EnumTests1() { Mapper.CreateMapper<B, A>(); var a = Mapper.Map<B,A>(new B()); Assert.IsTrue(a.en1 == En1.c); Assert.IsTrue(a.en2 == En2.c); Assert.IsTrue(a.en3 == En3.c); Assert.IsTrue(a.en4 == 2); Assert.IsTrue(a.en6 == En1.c); Assert.IsTrue(a.en7 == En3.c); Assert.IsTrue(a.en8 == En3.c); Assert.IsNull(a.en9); } }
3. Nullable -> Primitive,
Assert.AreEqual(true, Mapper.Map<bool?, bool>(true)); Assert.AreEqual(false, Mapper.Map<bool?, bool>(false)); Assert.AreEqual(false, Mapper.Map<bool?, bool>(null));
4. Primitive -> Nullable
Assert.AreEqual(true, Mapper.Map<bool, bool?>(true)); Assert.AreEqual(false, Mapper.Map<bool, bool?>(false));
5. Nullable -> Nullable
Assert.IsFalse(Mapper.Map<sbyte?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<Char?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<Byte?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<Int16?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<UInt16?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<Int32?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<UInt32?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<Int64?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<UInt64?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<Single?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<Double?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<Decimal?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<DateTime?, Boolean?>(null).HasValue); Assert.IsFalse(Mapper.Map<Boolean?, Char?>(null).HasValue); Assert.IsFalse(Mapper.Map<sbyte?, Char?>(null).HasValue); Assert.IsFalse(Mapper.Map<Byte?, Char?>(null).HasValue); Assert.IsFalse(Mapper.Map<Int16?, Char?>(null).HasValue); Assert.IsFalse(Mapper.Map<UInt16?, Char?>(null).HasValue); Assert.IsFalse(Mapper.Map<Int32?, Char?>(null).HasValue); Assert.IsFalse(Mapper.Map<UInt32?, Char?>(null).HasValue); Assert.IsFalse(Mapper.Map<Int64?, Char?>(null).HasValue); Assert.IsFalse(Mapper.Map<UInt64?, Char?>(null).HasValue); Assert.IsFalse(Mapper.Map<Single?, Char?>(null).HasValue); Assert.IsFalse(Mapper.Map<Double?, Char?>(null).HasValue); Assert.IsFalse(Mapper.Map<Decimal?, Char?>(null).HasValue); Assert.IsFalse(Mapper.Map<DateTime?, Char?>(null).HasValue); 。。。
6. Null -> Primitive
object d = null; object t = Mapper.Map(d, null, typeof(Int32)); Assert.IsInstanceOf<int>(t);
