【问题描述】：

我注意到的是，在 Ncv 中，我引用的报告字段没有生成。以下是我收到的错误。

这是我的域的样子，我收到的错误是 Invalid index 1 for this SqlParameterCollection with Count=1。

public class NcvMap : SubclassMap<Ncv>
{
    public NcvMap()
    {
        HasManyToMany<Document>(x => x.Technician)
            .Cascade.All();

        HasManyToMany<Document>(x => x.Neurologist)
            .Cascade.All();

        HasManyToMany<Document>(x => x.Transcriber)
            .Cascade.All();

        References<Document>(x => x.Report).Nullable();
    }
}

public class Ncv : Report
{
    public virtual IList<Document> Technician { get; private set; }
    public virtual IList<Document> Neurologist { get; private set; }
    public virtual IList<Document> Transcriber { get; private set; }
    public virtual Document Report { get; set; }
    public virtual NcvType Type { get; set; }

    public Ncv()
    {
        this.Technician = new List<Document>();
        this.Neurologist = new List<Document>();
        this.Transcriber = new List<Document>();
    }
}

public class Report : BaseModel
{
    public virtual Patient Patient { get; set; }
    public virtual ReportStatus Status { get; set; }
    public virtual DateTime Appointment { get; set; }
    public virtual long Kareo_id { get; set; }
    public virtual IList<ReportLog> Logs { get; private set; }

    public Report() 
    {
        this.Status = ReportStatus.New;
        this.Logs = new List<ReportLog>();
    }

    public virtual void AddLog(ReportLog log)
    {
        log.Report = this;
        this.Logs.Add(log);
    }
}

public class ReportMap : ClassMap<Report>
{
    public ReportMap()
    {
        Id(x => x.Id);
        Map(x => x.CreateDate);
        Map(x => x.LastModified);
        Map(x => x.Appointment);
        Map(x => x.Status).CustomType<int>();
        Map(x => x.Kareo_id);

        HasMany<ReportLog>(x => x.Logs)
            .Cascade.All();

        References<Patient>(x => x.Patient);
    }
}

【问题讨论】：

你应该读取索引 0 因为 c# 数组以 0 开头
索引 0？我什至不确定索引 1 是什么。

标签： c# nhibernate fluent-nhibernate fluent-nhibernate-mapping

【解决方案1】：

好的，问题是在

public class Ncv : Report

我将映射引用命名为与“报告”类相同的名称

public virtual Document Report { get; set; }

因此，请勿使用与类相同的名称来命名您的属性。它破坏了 CreateSchema
