AutoMapper.Mapper 不包含 CreateMap 的定义

使用AutoMapper.Mapper进行对象映射是在.NET开发中常用的技术之一。AutoMapper.Mapper是一个强大且灵活的库，它可以帮助我们简化对象之间的转换过程，提高开发效率。在本文中，我们将通过几个例子来介绍AutoMapper.Mapper的基本用法。

csharp
using AutoMapper;
// 定义源对象
public class SourceObject
{
    public string Name { get; set; }
    public int Age { get; set; }
}
// 定义目标对象
public class DestinationObject
{
    public string Name { get; set; }
    public int Age { get; set; }
}
// 创建映射关系
Mapper.CreateMap();
// 使用映射关系进行对象转换
SourceObject source = new SourceObject { Name = "John", Age = 25 };
DestinationObject destination = Mapper.Map(source);
// 输出转换结果
Console.WriteLine(destination.Name);  // 输出：John
Console.WriteLine(destination.Age);   // 输出：25

csharp
using AutoMapper;
public class SourceObject
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}
public class DestinationObject
{
    public string FullName { get; set; }
}
Mapper.CreateMap()
    .ForMember(dest => dest.FullName, opt => opt.MapFrom(src => src.FirstName + " " + src.LastName));
SourceObject source = new SourceObject { FirstName = "John", LastName = "Doe" };
DestinationObject destination = Mapper.Map(source);
Console.WriteLine(destination.FullName);  // 输出：John Doe

csharp
using AutoMapper;
public class SourceObject
{
    public string Name { get; set; }
    public int Age { get; set; }
}
public class DestinationObject
{
    public string Name { get; set; }
    public int Age { get; set; }
}
Mapper.CreateMap();
List sourceList = new List
{
    new SourceObject { Name = "John", Age = 25 },
    new SourceObject { Name = "Jane", Age = 30 }
};
List destinationList = Mapper.Map, List>(sourceList);
foreach (var item in destinationList)
{
    Console.WriteLine(item.Name);  // 输出：John, Jane
    Console.WriteLine(item.Age);   // 输出：25, 30
}
