Fluent Nhibernate List <string>映射

Question

我有一个带有IList<string>属性的简单类.如何在Fluent Nhibernate中映射此房源？

[Serializable]
public class ExportTask
{
    private IList<string> _csvExportList = new List<string>();

    public ExportTask()
    {}

    public virtual IList<string> CsvExportList
    {
        get { return _csvExportList; }
        set { _csvExportList = value; }
    }
}

public class ExportTaskMap : SubclassMap<ExportTask>
{
    public ExportTaskMap()
    {           
        HasMany(x => x.CsvExportList)
               .Element("CsvExportList")
               .Cascade
               .AllDeleteOrphan();
    }
}

发生以下错误:

Initializing -failed to lazily initialize a collection of role: MyApp.Tasks.ExportTask.CsvExportList, no session or session was closed

在集合上调用addrange时:

var exportList = new List<string>()
                     {
                        {"item1"},
                        {"item2"}
                      };

CsvExportList.AddRange(exportList);

事实证明,我们可以使用AsList列的列表索引和allworks的映射.我想知道为什么这个简单的用例没有答案.希望它有助于某人.

public class ExportTaskMap : SubclassMap<ExportTask>
{
  public ExportTaskMap()
  {           
     HasMany(x => x.CsvExportList)
           .Element(@"CsvProperty")
           .KeyColumn(@"ExportTask_id")
           .Table(@"CsvExportProperties")
           .AsList(x => x.Column(@"CsvPropertyListIndex"))
           .Not.LazyLoad();
  }
}

映射表在数据库中看起来如下所示.
