C# 在linq to sql中插入子记录后刷新实体

我正在插入与现有父记录关联的子记录。如何刷新父记录以显示所有记录，包括新插入的子记录

context.Refresh（RefreshMode.OverwriteCurrentValues，entity）

不起作用

我尝试的一个更完整的例子：

Location newLocation = Json.deserialize<Location>(json);
if (newLocation != null) {
    IEnumerable<string> zipCodes = Regex.Split(newLocation.zipCodes, @"[\s,;]+");

    // this verifies the new zipcodes against a table of all US zipcodes and returns matches 
    var newLocationZipCodes = _zipCodeRepository.match(zipCodes).Select(item => new LocationZipCode { idLocation = newLocation.id, state = item.state, zipcode = item.zipcode });

    // get the parent entity
    var domainLocation = _unitOfWork.locationRepository.getFirst(l => l.id == newLocation.id);

    // insert child entities
    if (newLocationZipCodes.Any()) {
        _unitOfWork.locationZipCodeRepository.insertAll(newLocationZipCodes);
        _unitOfWork.saveChanges(ConflictMode.ContinueOnConflict);
    }

    // this isn't working
    _unitOfWork.refresh(RefreshMode.OverwriteCurrentValues, domainLocation);
    return domainLocation;
}

---

我没有刷新上下文，而是改变了将子记录插入数据库的方式。所以不是

_unitOfWork.locationZipCodeRepository.insertAll(newLocationZipCodes);

我在做这个

domainLocation.LocationZipCodes.AddRange(newLocationZipCodes);

所以更新后的代码看起来是这样的

Location newLocation = Json.deserialize<Location>(json);
if (newLocation != null) {
    IEnumerable<string> zipCodes = Regex.Split(newLocation.zipCodes, @"[\s,;]+");

    var newLocationZipCodes = _zipCodeRepository.match(zipCodes).Select(item => new LocationZipCode { idLocation = newLocation.id, state = item.state, zipcode = item.zipcode });
    var domainLocation = _unitOfWork..locationRepository.getFirst(l => l.id == newLocation.id);

    if (newLocationZipCodes.Any()) {
        domainLocation.LocationZipCodes.AddRange(newLocationZipCodes);
        _unitOfWork.saveChanges(ConflictMode.ContinueOnConflict);
    }

    return new Mapper<DomainLocation, Location>(new LocationMapTemplate()).map(domainLocation);
}

Location newLocation=Json.反序列化（Json）；
if（newLocation！=null）{
IEnumerable zipCodes=Regex.Split（newLocation.zipCodes，@“[\s，；]+”；
var newLocationZipCodes=_zipCodeRepository.match（zipCodes）.Select（item=>newlocationzipcode{idLocation=newLocation.id，state=item.state，zipcode=item.zipcode}）；
var domainLocation=\u unitOfWork..locationRepository.getFirst（l=>l.id==newLocation.id）；
if（newLocationZipCodes.Any（））{
domainLocation.LocationZipCodes.AddRange（newLocationZipCodes）；
_unitOfWork.saveChanges（ConflictMode.ContinueOnConflict）；
}
返回新映射器（new LocationMapTemplate（））.map（domainLocation）；
}

domainLocation.LocationZipCodes.AddRange(newLocationZipCodes);

Location newLocation = Json.deserialize<Location>(json);
if (newLocation != null) {
    IEnumerable<string> zipCodes = Regex.Split(newLocation.zipCodes, @"[\s,;]+");

    var newLocationZipCodes = _zipCodeRepository.match(zipCodes).Select(item => new LocationZipCode { idLocation = newLocation.id, state = item.state, zipcode = item.zipcode });
    var domainLocation = _unitOfWork..locationRepository.getFirst(l => l.id == newLocation.id);

    if (newLocationZipCodes.Any()) {
        domainLocation.LocationZipCodes.AddRange(newLocationZipCodes);
        _unitOfWork.saveChanges(ConflictMode.ContinueOnConflict);
    }

    return new Mapper<DomainLocation, Location>(new LocationMapTemplate()).map(domainLocation);
}
