SqlBulkCopy 来自数据源的 String 类型的给定值不能转换为指定目标列的类型 bit

DataTable与要插入的数据表要字段名，位置，数据类型都一至才可

示例，使用使用SqlBulkCopy插入多个表

        public bool BatchInsertUniqeCode(DataTable uniqueCodeProduceContrastDt,DataTable uniqueCodeGenerateDt)
        {
            using(SqlConnection conn= (SqlConnection)(base.DbContext.Database.Connection))
            {
                if (conn.State == ConnectionState.Closed) { conn.Open(); }
                SqlTransaction tran = conn.BeginTransaction();
                SqlBulkCopy upBlock = new SqlBulkCopy(conn, SqlBulkCopyOptions.Default, tran);
                SqlBulkCopy ugBlock = new SqlBulkCopy(conn, SqlBulkCopyOptions.Default, tran);
                try
                {
                    ugBlock.DestinationTableName = "UniqueCodeGenerate";
                    ugBlock.BatchSize = uniqueCodeGenerateDt.Rows.Count;
                    if (uniqueCodeGenerateDt != null && uniqueCodeGenerateDt.Rows.Count > 0)
                    {
                        ugBlock.WriteToServer(uniqueCodeGenerateDt);
                    }
                    ugBlock.Close();


                    upBlock.DestinationTableName = "UniqueCodeProduceContrast";
                    upBlock.BatchSize = uniqueCodeProduceContrastDt.Rows.Count;
                    if (uniqueCodeProduceContrastDt != null && uniqueCodeProduceContrastDt.Rows.Count > 0)
                    {
                        upBlock.WriteToServer(uniqueCodeProduceContrastDt);
                    }
                    upBlock.Close();

                    tran.Commit();
                    return true;
                }
                catch(Exception ex)
                {
                    tran.Rollback();
                    throw ex;
                }
                finally
                {
                    upBlock.Close();
                    ugBlock.Close();
                    conn.Close();
                }

            }

        }
