捕获插入的行并返回到客户端应用程序

Question

我基本上需要捕获插入行的 id 并将其返回给 angular 应用程序。 下面的代码来自asp.net web api 应用程序。 我已经声明了一个整数数组

int[] documentIds = null 。

mgrDocument 包含执行后的 id

mgrDocument = mgrDocumentService.Create(mgrDocument);

如何将该值添加到整数数组并通过 webapi 返回它。 我有一个 foreach 循环，因此没有索引，否则我会做

documentIds[index] = mgrDocument.ID;

检索到所有 id 后，我需要将其发送给客户端以查询这些 id。 然后我如何返回这些 ID。

网络接口

  [HttpPost]
        [SkipTokenAuthorization]
        [Route("api/documentupload/create")]
        public HttpResponseMessage Create(DocumentUploadCreateViewModel model)
        {
            HttpResponseMessage response;

            var mgrStrategyDocument = new MANAGERSTRATEGY_DOCUMENT();
            var mgrDocumentService = GetService<DOCUMENT>();
            var mgrStrategyDocumentService = GetService<MANAGERSTRATEGY_DOCUMENT>();
            int[] documentIds = null;

            if (model != null)
            {
                foreach (var obj in model.DocumentDetails)
                {
                    var mgrDocument = new DOCUMENT
                    {
                        DOCUMENT_TYPE_ID = obj.DocumentTypeId,
                        DOCUMENT_DATE = obj.DocumentDate,
                        NAME = obj.Name,
                        DOCUMENT_CONTENT = convertByteArray(obj.file),
                        EXTENSION = GetFileExtension(obj.Name)
                };
                    mgrDocument = mgrDocumentService.Create(mgrDocument);
                    documentIds[obj] = mgrDocument.ID;

                    var mangerStrategyDocumentService = GetService<MANAGERSTRATEGY_DOCUMENT>();
                    var mgrStrategyDocument1 = new MANAGERSTRATEGY_DOCUMENT()
                    {
                        DOCUMENT_ID = mgrDocument.ID,
                        MANAGERSTRATEGY_ID = model.ManagerStrategyId

                    };
                    mgrStrategyDocument = mgrStrategyDocumentService.Create(mgrStrategyDocument1);

                }
               return  response = Request.CreateResponse(HttpStatusCode.OK, mgrStrategyDocument);
            }
           return null;

        }

这就是 MANAGERSTRATEGY_DOCUMENT 的样子

{Permal.BSG.Manager.Core.Model.MANAGERSTRATEGY_DOCUMENT}
    CREATED_BY_ID: 0
    DATE_CREATED: {07/07/2019 08:01:17}
    DOCUMENT: {Permal.BSG.Manager.Core.Model.DOCUMENT}
    DOCUMENT_ID: 590834
    ID: 186423
    LAST_MODIFIED: {07/07/2019 08:01:17}
    LAST_MODIFIED_BY_ID: 0
    MANAGERSTRATEGY_ID: 7079
    ManagerStrategy: null

我已经通过implementint return type of List解决了

 [HttpPost]
        [SkipTokenAuthorization]
        [Route("api/documentupload/create")]
        public List<int> Create(DocumentUploadCreateViewModel model)
        {
            HttpResponseMessage response;

            var mgrStrategyDocument = new MANAGERSTRATEGY_DOCUMENT();
            var mgrDocumentService = GetService<DOCUMENT>();
            var mgrStrategyDocumentService = GetService<MANAGERSTRATEGY_DOCUMENT>();
            List<int> documentIds = new List<int>();


            if (model != null)
            {
                foreach (var obj in model.DocumentDetails)
                {
                    var mgrDocument = new DOCUMENT
                    {
                        DOCUMENT_TYPE_ID = obj.DocumentTypeId,
                        DOCUMENT_DATE = obj.DocumentDate,
                        NAME = obj.Name,
                        DOCUMENT_CONTENT = convertByteArray(obj.file),
                        EXTENSION = GetFileExtension(obj.Name)
                };
                    mgrDocument = mgrDocumentService.Create(mgrDocument);
                    documentIds.Add(mgrDocument.ID);
                    var mangerStrategyDocumentService = GetService<MANAGERSTRATEGY_DOCUMENT>();
                    var mgrStrategyDocument1 = new MANAGERSTRATEGY_DOCUMENT()
                    {
                        DOCUMENT_ID = mgrDocument.ID,
                        MANAGERSTRATEGY_ID = model.ManagerStrategyId

                    };
                    mgrStrategyDocument = mgrStrategyDocumentService.Create(mgrStrategyDocument1);

                }

                return documentIds;
                //return  response = Request.CreateResponse(HttpStatusCode.OK, mgrStrategyDocument);
            }
           return null;

        }
