3、重新生成dll



4、重新打开销售出库单列表,点按钮,先导出Excel,

4.1、修改表名为Sheet1,填写运单号、物流公司信息

5、点按钮,导入

这节比较复杂,很奇怪,提示   没有找到模板请重新选择,dtexcel总是null空值,待续......


        //判断是否上传Excel表格
        private bool IsNotNull()
        {
            ExcelOperation excelOperation = new ExcelOperation();
            DataSet dataSet = null;
            dataSet = excelOperation.ReadFromFile(this._filePath, 0, 0);
            dtexcel = dataSet.Tables["Sheet1"];
            if (dtexcel == null)
            {
                this.View.ShowMessage("没有找到模板请重新选择!");
                return false;
            }
            return true;
        }


如果提示上面报错,添加3行数据再试下;


不能只填写一行数据;
