AutoMapper中ForMember方法编译错误。无效的重载。

8

我将尝试使用Automapper进行映射。

这是我当前的映射代码：

Mapper.CreateMap(Of NameAddress, PersonalDetails)() _
            .ForMember(Function(dest) dest.Forenames, Function(opt) opt.MapFrom(Function(src) src.Forename)) _
            .ForMember(Function(dest) dest.TelephoneNumber, Function(opt) opt.MapFrom(Function(src) src.TelephoneNo1)) _
            .ForMember(Function(dest) dest.MobileNumber, Function(opt) opt.MapFrom(Function(src) src.MobilePhoneNo)) _
            .ForMember(Function(dest) dest.NationalInsuranceNumber, Function(opt) opt.MapFrom(Function(src) src.NINo)) _
            .ForMember(Function(dest) dest.DateOfBirth, Function(opt) opt.MapFrom(Function(src) src.BirthDate))

我想从一个NameAddress源对象映射到PersonalDetails目标对象。源和目标的其余属性都相同，因此未显式定义映射。

然而，当我尝试使用这个映射编译时，我会得到以下编译时错误。

Overload resolution failed because no accessible 'ForMember' can be called with these arguments:
    'Public Function ForMember(name As String, memberOptions As System.Action(Of AutoMapper.IMemberConfigurationExpression(Of Infrastructure.NameAddress))) As AutoMapper.IMappingExpression(Of Infrastructure.NameAddress, Core.TaxiLicensing.PersonalDetails)': Lambda expression cannot be converted to 'String' because 'String' is not a delegate type.
    'Public Function ForMember(name As String, memberOptions As System.Action(Of AutoMapper.IMemberConfigurationExpression(Of Infrastructure.NameAddress))) As AutoMapper.IMappingExpression(Of Infrastructure.NameAddress, Core.TaxiLicensing.PersonalDetails)': Expression does not produce a value.
    'Public Function ForMember(destinationMember As System.Linq.Expressions.Expression(Of System.Func(Of Core.TaxiLicensing.PersonalDetails, Object)), memberOptions As System.Action(Of AutoMapper.IMemberConfigurationExpression(Of Infrastructure.NameAddress))) As AutoMapper.IMappingExpression(Of Infrastructure.NameAddress, Core.TaxiLicensing.PersonalDetails)': Expression does not produce a value.

我错过了什么？我的映射有误吗？它似乎试图使用我不想使用的函数重载。

 Mapper.CreateMap(Of Category, DTOCategory)() _
         .ForMember(Function(c) c.ID, Sub(opt) opt.Ignore()) _
         .ForMember(Function(c) c.NAME, Sub(opt) opt.Ignore())

我的错误...

本应该使用：

Mapper.CreateMap(Of NameAddress, PersonalDetails)() _
            .ForMember(Function(dest) dest.Forenames, Sub(opt) opt.MapFrom(function(src) src.Forename)) _
            .ForMember(Function(dest) dest.TelephoneNumber, sub(opt) opt.MapFrom(function(src) src.TelephoneNo1)) _
            .ForMember(Function(dest) dest.MobileNumber, Sub(opt) opt.MapFrom(function(src) src.MobilePhoneNo)) _
            .ForMember(Function(dest) dest.NationalInsuranceNumber, sub(opt) opt.MapFrom(function(src) src.NINo)) _
            .ForMember(Function(dest) dest.DateOfBirth, Sub(opt) opt.MapFrom(function(src) src.BirthDate))
