帮帮看看是啥引起的，我怀疑是SqlBulkCopy类引起的。这是截图

using (SqlConnection sqlConnection = new SqlConnection(connectionString))
                {
                    sqlConnection.Open();
                    SqlTransaction sqlTransaction = sqlConnection.BeginTransaction();
                    try
                    {
                        using (SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(sqlConnection, SqlBulkCopyOptions.TableLock, sqlTransaction))
                        {
                            sqlBulkCopy.BatchSize = batchSize;
                            sqlBulkCopy.BulkCopyTimeout = 3000;
                            sqlBulkCopy.DestinationTableName = tableName;
                            for (int i = 0; i < table.Columns.Count; i++)
                            {
                                sqlBulkCopy.ColumnMappings.Add(table.Columns[i].ColumnName, table.Columns[i].ColumnName);
                            }
                            sqlBulkCopy.WriteToServer(table);
                            sqlTransaction.Commit();
                        }
                        return true;
                    }
                    catch (Exception ex)
                    {
                        myex = ex;
                        sqlTransaction.Rollback();
                        f = true;
                    }
                }
