.NET Core中的SDO_GEOMETRY

Question

在使用最新版本的Oracle.ManagedDataAccess.Core nuget时，如果查询中的列包含SDO_GEOMETRY列，则连接将冻结。

我正在连接到Oracle 11g。

namespace OracleTest { using Oracle.ManagedDataAccess.Client; using System;

    public static class Program
    {
        public static void Main(string[] args)
        {
            var connection = new OracleConnection("Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=xe)));User Id=system;Password=oracle");
            connection.Open();

            OracleCommand command = connection.CreateCommand();
            command.CommandText = "SELECT ID, sdo_geometry_notnull FROM GeometryTypesTestTable";

            //code freezes here
            OracleDataReader reader = command.ExecuteReader();

            Console.WriteLine("Done");
            Console.ReadLine();
        }
    }
}

public static class Program { public static void Main(string[] args) { var connection = new OracleConnection("Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=xe)));User Id=system;Password=oracle"); connection.Open(); OracleCommand command = connection.CreateCommand(); command.CommandText = "SELECT ID, sdo_geometry_notnull FROM GeometryTypesTestTable"; //code freezes here OracleDataReader reader = command.ExecuteReader(); Console.WriteLine("Done"); Console.ReadLine(); } } }

有什么方法或方法可以从SDO_GEOMETRY列中获取某种模型或数据吗？
