使用MySqlBulkLoader报“don't support load data without local field”

在使用MySqlBulkLoader进行批量插入时用出现下面错误：
MySql.Data.MySqlClient.MySqlException:“Load Data: don't support load data without local field”

目前是否支持MySqlBulkLoader？如果不支持，批量插入时是否有类似的方法？

实现代码如下：
try
{
conn.Open();
tran = conn.BeginTransaction();
MySqlBulkLoader bulk = new MySqlBulkLoader(conn)
{
FieldTerminator = ",",
FieldQuotationCharacter = '"',
EscapeCharacter = '"',
LineTerminator = "\r\n",
FileName = tmpPath,
NumberOfLinesToSkip = 0,
TableName = table.TableName,
};

                bulk.Columns.AddRange(table.Columns.Cast<DataColumn>().Select(colum => colum.ColumnName).ToList());
                insertCount = bulk.Load();
                tran.Commit();
            }
            catch (MySqlException ex)
            {
                if (tran != null) tran.Rollback();
                throw ex;
            }
            finally
            {
                conn.Close();
                conn.Dispose();
            }

Start by checking the documentation for MySqlBulkLoader and the reported “don't support load data without local field” error against the provided C# example. Confirm whether the operation is supported and identify the documented bulk-insert alternative, then update the relevant Chinese documentation so the support status and recommended method are clear.
