Examples

This example shows how to explicitly convert one value to another. C#

[TestFixture]
public class MapMemberTests
{
  private class Class1
  {
    public int Prop1 { get; set; }
    public string Field1;
  }

  private class Class2
  {
    public string Prop1 { get; set; }
    public DateTime? Field1;
  }

  private static readonly Mapper<Class1, Class2> _class1ToClass2Mapper =
    Map.GetMapper<Class1, Class2>(
      m =>
        m.MapMember(c2 => c2.Field1, c1 => DateTime.Parse(c1.Field1).AddDays(1)));

  [Test]
  public void Test1()
  {
    var c2 = _class1ToClass2Mapper.Map(
      new Class1
      {
        Prop1 = 41,
        Field1 = "2016-01-01"
      });

    Assert.That(c2.Prop1, Is.EqualTo("41"));
    Assert.That(c2.Field1?.Year, Is.EqualTo(2016));
    Assert.That(c2.Field1?.Day, Is.EqualTo(2));
  }
