Question

我创建一些.csv文件并填写导出数据。这是我的代码：



public void ExportGoodList(int id)
        {
            List<LineItem> lineItems = _lineItemService.FindAllByApplicationId(id).ToList();
            Response.Clear();
            Response.AddHeader("Content-Disposition", "attachment; filename=Carnet" + id + ".csv");
            Response.Flush();
            Response.Write("Item Description");
            Response.Write(",");
            Response.Write("No. of Pieces (numbers only are allowed)");
            Response.Write(",");
            Response.Write("Weight/Volume (numbers only are allowed)");
            Response.Write(",");
            Response.Write("\"Unit of Measure (the following values are allowed only: g, kg, t, l)\"");
            Response.Write(",");
            Response.Write("Value (in GBP) (numbers only are allowed)");
            Response.Write(",");
            Response.Write("Country of Origin (the codes of the countries are allowed only)");
            Response.Write(",");
            Response.Write(" Goods Type ID (numbers only are allowed)");
            Response.Write(",");
            Response.Write("\n");
            foreach (var item in lineItems)
            {
                Response.Write(SanitizeData(item.Description));
                Response.Write(",");
                Response.Write(SanitizeData(item.NumberOfPieces));
                Response.Write(",");
                Response.Write(SanitizeData(item.Quantity));
                Response.Write(",");
                Response.Write(SanitizeData(item.QuantityUnits));
                Response.Write(",");
                Response.Write(SanitizeData(item.ItemValue));
                Response.Write(",");
                Response.Write(SanitizeData(item.CountryOfOrigin));
                Response.Write(",");
                Response.Write(SanitizeData(_goodsTypeService.GoodsTypeIdToUserDefinedId(item.GoodsType)));
                Response.Write("\n");
            }
        }

public void ExportGoodList(int id) { List<LineItem> lineItems = _lineItemService.FindAllByApplicationId(id).ToList(); Response.Clear(); Response.AddHeader("Content-Disposition", "attachment; filename=Carnet" + id + ".csv"); Response.Flush(); Response.Write("Item Description"); Response.Write(","); Response.Write("No. of Pieces (numbers only are allowed)"); Response.Write(","); Response.Write("Weight/Volume (numbers only are allowed)"); Response.Write(","); Response.Write("\"Unit of Measure (the following values are allowed only: g, kg, t, l)\""); Response.Write(","); Response.Write("Value (in GBP) (numbers only are allowed)"); Response.Write(","); Response.Write("Country of Origin (the codes of the countries are allowed only)"); Response.Write(","); Response.Write(" Goods Type ID (numbers only are allowed)"); Response.Write(","); Response.Write("\n"); foreach (var item in lineItems) { Response.Write(SanitizeData(item.Description)); Response.Write(","); Response.Write(SanitizeData(item.NumberOfPieces)); Response.Write(","); Response.Write(SanitizeData(item.Quantity)); Response.Write(","); Response.Write(SanitizeData(item.QuantityUnits)); Response.Write(","); Response.Write(SanitizeData(item.ItemValue)); Response.Write(","); Response.Write(SanitizeData(item.CountryOfOrigin)); Response.Write(","); Response.Write(SanitizeData(_goodsTypeService.GoodsTypeIdToUserDefinedId(item.GoodsType))); Response.Write("\n"); } }

然后下载了这个文件，我看到了所有导出数据。此.csv文件只有一个包含数据的工作表。我的目标是在此.csv文件中使用另一个数据创建另一个附加工作表。我不知道怎么做！

谢谢！

没有办法做到这一点。 CSV（以逗号分隔的值）是一种文本格式，它与Sheet和MVC都没有关系。

如果您需要将工作表添加到Excel文件，请参阅f.e。：C# how to add Excel Worksheet programmatically Office XP / 2003

使用.csv文件中的数据创建新工作表
