C# 如何使用dapper将多对多关系映射到列表

我有一个课堂规则

public class AnalysisRule
{
    public long Id { get; set; }
    public Analysis Analysis { get; set; }
    public AnalysisCategory AnalysisCategory { get; set; }
    public Gender Gender { get; set; }
    public bool FatherHerdBookRequired { get; set; }
    public bool MotherHerdBookRequired { get; set; }
    public List<Breed> AllowedBreeds { get; set; }
}

这是一个多对多关系，我用DB表绑定在一起 分析规则种子

繁殖

和分析规则

我已经试过了

    var sql = @"select *
                from ""AnalysisRules"" 
                join ""AnalysisCategory"" on ""AnalysisRules"".""AnalysisCategoryId"" = ""AnalysisCategory"".""Id""  
                join ""Analysis"" on ""AnalysisRules"".""AnalysisId"" = ""Analysis"".""Id""
                left join ""AnalysisRulesBreeds"" on ""AnalysisRulesBreeds"".""AnalysisRuleId"" = ""AnalysisRules"".""Id""
                left join ""Breed"" on ""AnalysisRulesBreeds"".""BreedId"" = ""Breed"".""BreedId""
                where ""AnalysisId"" = :AnalysisId";
    rules = sqlConnection.QueryAsync<AnalysisRule, AnalysisCategory, Analysis, Breed, AnalysisRule>(
        sql,
        (ar, c, a, b) =>
        {
            ar.AnalysisCategory = c;
            ar.Analysis = a;
            ar.Breeds.Add(b);
            return ar;
        },
        new
        {
            AnalysisId = analysisId
        },
        splitOn:"BreedId");

var sql=@“选择*
来自“分析规则”
在“AnalysisRules”“AnalysisCategoryId”“AnalysisCategory”“Id”“上加入“AnalysisCategory”
在“分析规则”上加入“分析”。“分析Id”=“分析”。“Id”
在“AnalysisRulesReeds”上左联接“AnalysisRulesReeds”。“AnalysisRuleId”=“AnalysisRules”。“Id”
在“AnalysisRulesReeds”“BreedId”“=”“BreedId”“”“BreedId”“上左键联接”“BreedId”“。”
其中“AnalysisId=：AnalysisId”；
rules=sqlConnection.QueryAsync
通过选择*可以获得每个联接表的列。您还将
splitOn
设置为
BreedId
。现在Dapper希望将一个联接表的行列与下一个联接表的行列分开，它应该查找名为
BreedId
的列

这不起作用，因为除
AnalysisRulesBreeds
之外的所有表都使用
Id
作为Id列名

尝试删除
splitOn
参数，然后它将默认为
Id
。然后调整select子句，只从结果中实际需要的表中进行选择，例如

选择分析规则。*，分析类别。*，分析。*，品种。*

（假设您的分析表和AnalysisCategory表遵循将Id列命名为“Id”的约定）。
已尝试根据您的建议进行编辑，但我仍然收到相同的错误，即使我仅在所有表中使用Id作为PK，请参阅编辑部分，以获取我在SQLDevice中获得的数据的屏幕截图。如果Dapper接收的结果包含屏幕转储中显示的id列名（id、id_1、id_2），则它将不起作用。神谕的事？SQL Server中的同一查询会将id列命名为id、id和id…然后我是否可以将每个列显式命名为“AnalysisCategoryId”并以某种方式进行拆分？是的，应该可以向拆分添加逗号分隔的列表，例如“AnalysisCategoryId，BreedId，…”。
