如果我要添加两个或更多实体，我必须在单个类中声明所有属性，以便从Ajax调用中的View中正确地将它们映射到JS。
只是检查我是否遗漏了AutoMapper可以做的事情，我没有使用......
例如，如果只使用一个实体（Customer），则AutoMapper中的以下内容可以正常工作：
Mapper.CreateMap<CustomerDTO, Customer>();
var customer = Mapper.Map<CustomerDTO, Customer>(custDTO);
如果使用两个或更多实体，我必须执行以下操作：
using (var dbcxtTrans = DbContext.Database.BeginTransaction(System.Data.IsolationLevel.RepeatableRead))
{
Customer cust = new Customer();
cust.Address1 = custProjDTO.customer_Address1;
cust.Address2 = custProjDTO.customer_Address2;
cust.CellPhone = custProjDTO.customer_CellPhone;
cust.City = custProjDTO.customer_City;
cust.Company = custProjDTO.customer_Company;
cust.CreatedDate = custProjDTO.customer_CreatedDate;
cust.Email = custProjDTO.customer_Email;
cust.FirstName = custProjDTO.customer_FirstName;
cust.HomePhone = custProjDTO.customer_HomePhone;
cust.IMAddress = custProjDTO.customer_IMAddress;
cust.LastName = custProjDTO.customer_LastName;
cust.State = custProjDTO.customer_State;
cust.UpdatedDate = custProjDTO.customer_UpdatedDate;
cust.UserName = custProjDTO.customer_UserName;
cust.Website = custProjDTO.customer_Website;
cust.Zip = custProjDTO.customer_Zip;
DbContext.Customers.Add(cust);
await DbContext.SaveChangesAsync();
Project proj = new Project();
proj.CustomerID = cust.CustomerID;
proj.CategoryID = custProjDTO.project_CategoryID;
proj.CreatedDate = custProjDTO.project_CreatedDate;
proj.Description = custProjDTO.project_Description;
proj.Name = custProjDTO.project_Name;
proj.Notes = custProjDTO.project_Notes;
proj.PriorityID = custProjDTO.project_PriorityID;
proj.Quote = custProjDTO.project_Quote;
proj.StatusID = custProjDTO.project_StatusID;
proj.UpdatedDate = custProjDTO.project_UpdatedDate;
DbContext.Projects.Add(proj);
await DbContext.SaveChangesAsync();
dbcxtTrans.Commit();
}
这是因为我的属性名称必须与视图中的名称一致（见下文）

@section Scripts {
<script>
$(document).ready(function ()
{
if (typeof contentCreateCustomerProject == "function")
contentCreateCustomerProject();
});
</script>
}
反过来，必须与我的JS属性对齐：
var customerProject_Input = {
customer_UserName: $('#customer_UserName').val(),
customer_Email: $('#customer_Email').val(),
customer_Company: $('#customer_Company').val(),
customer_FirstName: $('#customer_FirstName').val(),
customer_LastName: $('#customer_LastName').val(),
customer_Address1: $('#customer_Address1').val(),
customer_Address2: $('#customer_Address2').val(),
customer_City: $('#customer_City').val(),
customer_State: $('#customer_State').val(),
customer_Zip: $('#customer_Zip').val(),
customer_HomePhone: $('#customer_HomePhone').val(),
customer_CellPhone: $('#customer_CellPhone').val(),
customer_Website: $('#customer_Website').val(),
customer_IMAddress: $('#customer_IMAddress').val(),
customer_CreatedDate: currdate,
customer_UpdatedDate: null,
project_Name: $('#project_Name').val(),
project_Description: $('#project_Description').val(),
project_CategoryID: $('#project_CategoryID').val(),
project_PriorityID: $('#project_PriorityID').val(),
project_StatusID: $('#project_StatusID').val(),
project_Quote: $('#project_Quote').val(),
project_Notes: $('#project_Notes').val(),
project_CreatedDate: currdate,
project_UpdatedDate: null
};
反过来，只能在一个类中定义（见下文）：

答案 0 :(得分：1)
两个类中的属性名称不同，请尝试创建详细的映射配置，如：
Mapper.CreateMap<Customer, CustomerDTO>()
.ForMember(dest => dest.Address1,
opts => opts.MapFrom(src => src.customer_Address1))
.ForMember(dest => dest.Address2,
opts => opts.MapFrom(src => src.customer_Address2))
.ForMember(dest => dest.CellPhone,
opts => opts.MapFrom(src => src.customer_CellPhone))
.ForMember(dest => dest.City,
opts => opts.MapFrom(src => src.customer_City))
.ForMember(dest => dest.Company,
opts => opts.MapFrom(src => src.customer_Company))
.ForMember(dest => dest.CreatedDate,
opts => opts.MapFrom(src => src.customer_CreatedDate))
.ForMember(dest => dest.Email,
opts => opts.MapFrom(src => src.customer_Email))
.ForMember(dest => dest.FirstName,
opts => opts.MapFrom(src => src.customer_FirstName))
.ForMember(dest => dest.HomePhone,
opts => opts.MapFrom(src => src.customer_HomePhone))
.ForMember(dest => dest.IMAddress,
opts => opts.MapFrom(src => src.customer_IMAddress))
.ForMember(dest => dest.LastName,
opts => opts.MapFrom(src => src.customer_LastName))
.ForMember(dest => dest.State,
opts => opts.MapFrom(src => src.customer_State))
.ForMember(dest => dest.UpdatedDate,
opts => opts.MapFrom(src => src.customer_UpdatedDate))
.ForMember(dest => dest.UserName,
opts => opts.MapFrom(src => src.customer_UserName))
.ForMember(dest => dest.Website,
opts => opts.MapFrom(src => src.customer_Website))
.ForMember(dest => dest.Zip,
opts => opts.MapFrom(src => src.customer_Zip));
另外，对于保存对象，您不需要两次调用：
await DbContext.SaveChangesAsync();
只做一次：
DbContext.Projects.Add(proj);
DbContext.Customers.Add(cust);
await DbContext.SaveChangesAsync();
