使用ServiceStack ORMLite将DataTable传递给SP

Question

我必须调用存储过程,但传递一个数据表(一个iEnumerable)作为参数.

SQL服务器上的我的SP将此参数视为:

@LIST_USERS dbo.LIST_USERINFO_TYPE READONLY

并且类型定义为:

CREATE TYPE [dbo].[LIST_USERINFO_TYPE] AS TABLE(
   [ID_USER] [int] NOT NULL,
   [ID_DATA] [int] NOT NULL,
   [HEADER_TXT] [varchar](100) NULL)

然后,在调用者方面,我以这种方式创建参数:

list.Add(new UserInfoItem { IdUser = 401, IdData = 3, HeaderTxt = "" });
list.Add(new UserInfoItem { IdUser= 402, IdData= 2, HeaderTxt= "gotcha" });
list.Add(new UserInfoItem { IdUser= 403, IdData= 1, HeaderTxt= "pacific rim" });

dbConn.StoredProcedure(sp,
  new
    {
      LISTA_QUESTIONARIO = DomandeRisposteList
    });

当我启动项目实际上它停止KeyNotFoundException尝试

name.DbType = OrmLiteConfig.DialectProvider.GetColumnDbType(propertyInfo.PropertyType);

在 ServiceStackExtension.cs

我怎样才能做到这一点？

我已经使用简单的数据表找到了我自己的答案:

        DataTable dataTableTmp = new DataTable();
        dataTableTmp.Columns.Add("ID_USER", typeof(Int32));
        dataTableTmp.Columns.Add("ID_DATA", typeof(Int32));
        dataTableTmp.Columns.Add("HEADER_TXT", typeof(string));


        foreach (var r in DomandeRisposteList)
        {
            DataRow ro = dataTableTmp.NewRow();
            ro[0] = r.IdUser;
            ro[1] = r.IdData ;
            ro[2] = r.HeaderTxt ;

            dataTableTmp.Rows.Add(ro);
        }

        var dbConn = dbFactory.OpenDbConnection();

        var res = dbConn.Exec(dbCmd =>
        {
            dbCmd.CommandType = CommandType.StoredProcedure;
            dbCmd.Parameters.Add(new SqlParameter("@LISTA_QUESTIONARIO", dataTableTmp));
            dbCmd.CommandText = "IF_SP_QUESTIONARIO_INSERT_TEST";
            return dbCmd.ExecuteReader().ConvertToList<DomandeRisposteItem>(); 
        });

        return res;
