Question

这是角度http呼叫：

$http({
        url: "SingleSNP30second.aspx/GetSummary",
        method: "POST",
        data: { summaryId: $scope.summaryId },
        headers: { 'Content-Type': 'application/json; charset=utf-8' }
    });

这是asp web方法：

[WebMethod]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public static List<SummaryInfoJson> GetSummary(int summaryId)
    {
        DeveloprodDataClassDataContext masterDb = new DeveloprodDataClassDataContext();
        List<SummaryInfoJson> Summaries = (from t in masterDb.tbl_thirty_second_summaries_single_snps
                            join g in masterDb.tbl_custom_SNP_Genotypes on t.GenotypeId equals g.GenotypeId_this
                            join v in masterDb.tbl_custom_SNP_Variants on t.VariantId equals v.SnpsVariantId_this
                            join s in masterDb.tbl_thirty_second_summaries_stop_light_colors on t.StopLightColorId equals s.StopLightColorId_this
                            join l in masterDb.tbl_thirty_second_summaries_levels_of_evidences on t.LevelOfEvidenceId equals l.LevelOfEvidenceId_this
                            join d in masterDb.tbl_custom_SNP_Drugs_Apelon_NUIs on t.DrugId equals d.SnpsDrugId_this
                            join m in masterDb.tbl_thiry_second_summaries_summary_states on t.SummaryStateId equals m.SummaryStateId_this
                            join u in masterDb.tbl_users on t.EntrantUserId equals u.userId_this
                            where t.OriginalSummaryId == summaryId
                            select new SummaryInfoJson
                                (
                                t.ThirtySecondSummaryId_this,
                                d.Drug,
                                v.Variant,
                                g.Genotype,
                                t.ThirtySecondSummary,
                                s.StopLightColor,
                                l.LevelOfEvidence,
                                u.userName,
                                m.SummaryState
                                )
                        ).ToList();
        return Summaries;
    }

以下是SummaryInfoJson类的定义：

[Serializable]
    public class SummaryInfoJson
    {
        int ThirtySecondSummaryId;
        string Drug {get; set;}
        string Variant {get; set;}
        string Genotype {get; set;}
        string ThirtySecondSummary { get; set; }
        string StopLightColor { get; set; }
        string LevelOfEvidence { get; set; }
        string UserName { get; set; }
        string SummaryState { get; set; }

        public SummaryInfoJson(int thirtySecondSummaryId, string drug, string variant, string genotype, string thirtySecondSummary, string stopLightColor,
            string levelOfEvidence, string userName, string summaryState)
        {
            this.ThirtySecondSummaryId = thirtySecondSummaryId;
            this.Drug = drug;
            this.Variant = variant;
            this.Genotype = genotype;
            this.ThirtySecondSummary = thirtySecondSummary;
            this.StopLightColor = stopLightColor;
            this.LevelOfEvidence = levelOfEvidence;
            this.UserName = userName;
            this.SummaryState = summaryState;
        }
    }

在调试时，我可以看到数据库调用正常工作，Summaries初始化为SummaryInfoJson对象的List。不知怎的，http响应不包含对象，它只是一个空数组......

我没有包含SummaryInfoJson的定义以及数据库调用以保持代码简短。如果你愿意，我绝对可以提供。

编辑：好的，我在网络方法中添加了以下内容：

string returnVar =  new JavaScriptSerializer().Serialize(Summaries);
            return returnVar;

returnVar为空。错误发生在序列化中。为什么我的列表没有被序列化？我将serializable属性添加到该类定义..

Answer 1

尝试制作SummaryInfoJson public的属性，例如

public class SummaryInfoJson
{
    public string Drug {get; set;}
    public string Variant {get; set;}
    ....
}

json数据没有使用angular和asp webmethod回到客户端
