Question

我在默认端口1433上运行。当我对数据库执行简单查询时，一切正常。但是当我尝试运行存储过程时..像这样：

DataTable result = null;

SqlCommand command = new SqlCommand();
command.CommandType = System.Data.CommandType.StoredProcedure;
command.CommandText = procedureNameWithDbVersionPrefix;
command.CommandTimeout = m_nTimeout;
foreach (string item in m_Parameters.Keys)
{
    command.Parameters.Add(new SqlParameter(item, m_Parameters[item]));
}
string sConn = GetConnectionString();
using (SqlConnection con = new SqlConnection(sConn))
{
    try
    {
        con.Open();
        command.Connection = con;

        SqlQueryInfo queryInfo = Utils.GetSqlDataMonitor(command);
        using (KMonitor km = new KMonitor(KLogMonitor.Events.eEvent.EVENT_DATABASE, null, null, null, null) { Database = queryInfo.Database, QueryType = queryInfo.QueryType, Table = queryInfo.Table, IsWritable = (m_bIsWritable || Utils.UseWritable).ToString() })
        {
            using (SqlDataReader reader = command.ExecuteReader())
            {
                if (reader.HasRows)
                {
                    result = new DataTable();
                    result.Load(reader);
                }
            }
        }

        con.Close();
    }
    catch (Exception ex)
    {
        string sMes = "While running : '" + procedureNameWithDbVersionPrefix + "'\r\n Exception occurred: " + ex.Message;
        log.Error(sMes, ex);
        return null;
    }
}

我仅在Linux系统上遇到此异常。在Windows上运行都正常。实际上，在Windows上的基于Linux的docker中运行的事件均正常运行.. ::
