我有这两个表“ User”和“ Project”。他们分享一对多的关系。 我得到的响应是一个列表，我想用我创建的GetProjectManager的dto映射此响应，但是我不确定如何在自动映射器配置文件中定义CreateMap。 我从ProjectManager类型的API得到以下响应：
ProjectManager：
'Insert Shape into Footer
'behaves differently for doc/docx
Sub CATMain()
Dim strPathImg As String
strPathImg = "C:\Test\avatar.jpg"
Dim wrdApp
Set wrdApp = CreateObject("Word.Application")
wrdApp.Visible = True
Dim myWrdDoc
Set myWrdDoc = 'wrdApp.Documents.Open("C:\Test\Document.doc") 'change path for .docx to: "C:\Test\Document.docx"
Dim wrdFootShape
Set wrdFootShape = myWrdDoc.Sections.Last.Footers(1).Shapes
Dim objPic As Object
Dim posPic As Double
'Convert position in centimeters to points for the AddPicture method
posPic = CentimetersToPoints(2)
If myWrdDoc.SaveFormat = 0 Then
'correction for doc file
posPic = posPic - myWrdDoc.PageSetup.PageHeight + myWrdDoc.PageSetup.TopMargin
ElseIf myWrdDoc.SaveFormat = 12 Then
'docx file
posPic = posPic
End If
Set objPic = wrdFootShape.AddPicture(fileName:=strPathImg, _
LinkToFile:=False, SaveWithDocument:=True, Left:=120, Top:=posPic)
End Sub
我想将此响应与我创建的Dto（GetProjectManager）映射。

首先，您需要将响应json映射为类型
namespace Response
{
public class ProjectManager
{
public int id { get; set; }
public int projectId { get; set; }
public int userId { get; set; }
public Project project { get; set; }
public User user { get; set; }
}
public class Project
{
public int id { get; set; }
public string projectName { get; set; }
public DateTime plannedStartDate { get; set; }
public DateTime plannedEndDate { get; set; }
public object actualStartDate { get; set; }
public object actualEndDate { get; set; }
public string projectDescription { get; set; }
public object[] onProjects { get; set; }
public object[] projectManagers { get; set; }
}
public class User
{
public string firstName { get; set; }
public string lastName { get; set; }
public bool isProjectManager { get; set; }
public DateTime registrationTime { get; set; }
public object employees { get; set; }
public int id { get; set; }
public string userName { get; set; }
}
}
这是你的dto
namespace Dto
{
public class GetProjectManager
{
public string ProjectManagerId { get; set; }
public string Email { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public IList<GetProjectDto> GetProjects { get; set; }
}
public class GetProjectDto
{
public int ProjectId { get; set; }
public string ProjectName { get; set; }
public DateTime PlannedStartDate { get; set; }
public DateTime PlannedEndDate { get; set; }
public DateTime? ActualStartDate { get; set; }
public DateTime? ActualEndDate { get; set; }
public string ProjectDescription { get; set; }
}
}
然后，创建自动映射器配置文件以响应dto映射
public class ResponseToDtoProfile : AutoMapper.Profile
{
public ResponseToDtoProfile()
{
CreateMap<Response.Project, Dto.GetProjectDto>()
.ForMember(dst => dst.ProjectId, opt => opt.MapFrom(src => src.id))
.ForMember(dst => dst.ProjectName, opt => opt.MapFrom(src => src.projectName))
.ForMember(dst => dst.PlannedStartDate, opt => opt.MapFrom(src => src.plannedStartDate))
.ForMember(dst => dst.PlannedEndDate, opt => opt.MapFrom(src => src.plannedEndDate))
.ForMember(dst => dst.ActualStartDate, opt => opt.MapFrom(src => src.actualStartDate))
.ForMember(dst => dst.ActualEndDate, opt => opt.MapFrom(src => src.actualEndDate))
.ForMember(dst => dst.ProjectDescription, opt => opt.MapFrom(src => src.projectDescription));
CreateMap<Response.ProjectManager, Dto.GetProjectManager>()
.ForMember(dst => dst.ProjectManagerId, opt => opt.MapFrom(src => src.id))
.ForMember(dst => dst.FirstName, opt => opt.MapFrom(src => src.user.firstName))
.ForMember(dst => dst.LastName, opt => opt.MapFrom(src => src.user.lastName))
.ForMember(dst => dst.GetProjects, opt => opt.MapFrom(src => src.project));
}
}
要投影json数组，让我们在集合上添加扩展方法
public static class ExtensionsHelper
{
public static List<TProjection> ProjectAsCollection<TProjection>(this IEnumerable<object> items) where TProjection : class
{
//var adapter = <Create Type Adapter>
return adapter.Adapt<List<TProjection>>(items);
}
}
最后，您可以将json数组投影到dto。
static void Main(string[] args)
{
string jsonString = "[ { \"id\": 1, \"projectId\": 1, \"userId\": 1, \"project\": { \"id\": 1, \"projectName\": \"iDocument-FBAG\", \"plannedStartDate\": \"2019-07-03T00:00:00\", \"plannedEndDate\": \"2019-07-10T00:00:00\", \"actualStartDate\": null, \"actualEndDate\": null, \"projectDescription\": \"The client wants to enhance their existing .Net application. They have a WebForms application that uses DevExpress controls. They would like to start by implementing a chart type and creating a reusable report, also use that reusable report to implement some new reports.\", \"onProjects\": [], \"projectManagers\": [] }, \"user\": { \"firstName\": \"Abc\", \"lastName\": \"Efg\", \"isProjectManager\": true, \"registrationTime\": \"2019-06-28T19:28:55.8386138\", \"employees\": null, \"id\": 1, \"userName\": \"xyz@abc.com\" } }, { \"id\": 3, \"projectId\": 8, \"userId\": 1, \"project\": { \"id\": 8, \"projectName\": \"Aquatrols-FBAG\", \"plannedStartDate\": \"2019-07-03T00:00:00\", \"plannedEndDate\": \"2019-07-10T00:00:00\", \"actualStartDate\": null, \"actualEndDate\": null, \"projectDescription\": \"The client wants to enhance their existing .Net application. They have a WebForms application that uses DevExpress controls. They would like to start by implementing a chart type and creating a reusable report, also use that reusable report to implement some new reports.\", \"onProjects\": [], \"projectManagers\": [] }, \"user\": { \"firstName\": \"Abc\", \"lastName\": \"Efg\", \"isProjectManager\": true, \"registrationTime\": \"2019-06-28T19:28:55.8386138\", \"employees\": null, \"id\": 1, \"userName\": \"xyz@abc.com\" } } ]";
var rootObject = Newtonsoft.Json.JsonConvert.DeserializeObject<Response.ProjectManager[]>(jsonString).ToList().ProjectAsCollection<Dto.GetProjectManager>();
}
我希望能回答这个问题。

I had to play around with the CreateMap in the AutoMapper profile and it solved my problem.
这就是我定义映射的方式。
CreateMap<ProjectManager, GetProjectDto>()
.ForMember(dst => dst.ProjectId, opt => opt.MapFrom(src => src.Project.Id))
.ForMember(dst => dst.ProjectName, opt => opt.MapFrom(src => src.Project.ProjectName))
.ForMember(dst => dst.PlannedStartDate, opt => opt.MapFrom(src => src.Project.PlannedStartDate))
.ForMember(dst => dst.PlannedEndDate, opt => opt.MapFrom(src => src.Project.PlannedEndDate))
.ForMember(dst => dst.ActualStartDate, opt => opt.MapFrom(src => src.Project.ActualStartDate))
.ForMember(dst => dst.ActualEndDate, opt => opt.MapFrom(src => src.Project.ActualEndDate))
.ForMember(dst => dst.ProjectDescription, opt => opt.MapFrom(src => src.Project.ProjectDescription));
CreateMap<List<ProjectManager>, GetProjectManager>()
.ForMember(dst => dst.ProjectManagerId,
opt => opt.MapFrom(src =>
src.FirstOrDefault().UserId))
.ForMember(dst => dst.FirstName,
opt => opt.MapFrom(src =>
src.FirstOrDefault().User.FirstName))
.ForMember(dst => dst.LastName,
opt => opt.MapFrom(src =>
src.FirstOrDefault().User.LastName))
.ForMember(dst => dst.Email,
opt => opt.MapFrom(src =>
src.FirstOrDefault().User.Email))
.ForMember(dst => dst.GetProjects,
opt => opt.MapFrom(src =>
src.Select(x => new ProjectManager
{
Project = x.Project
})));
