Question

我创建了一个将Excel文件导出到gridView并将其导入到word的项目。现在，我通过单击发送到ExportData（）方法的每一行的ID来实现这一点。

现在我要实现的是，单击名为ImportALL的按钮，为gridView中的每一行创建单独的word文档。

例如，对于gridview中的每一行，我都想要类似

doc1.docx（包括gridview的第一行数据）

doc2.docx（包括gridview的第二行数据）

doc3.docx（包括gridview的第三行数据）

例如：

这是我的模特。cs

 public class Doc
{
    public int Id { get; set; }
    public string Name { get; set; }
    public decimal Price { get; set; }
    public string Quantity { get; set; }
    public string PriceWord { get; set; }

}

这是我的导出Excel数据控制台的内容

if (excelFile.FileName.EndsWith("xls") || excelFile.FileName.EndsWith("xlsx"))
            {
                string path = Server.MapPath("~/Content/" + excelFile.FileName);
                if (System.IO.File.Exists(path))
                {
                    System.IO.File.Delete(path);
                }
                excelFile.SaveAs(path);
                ExcelDoc.Application application = new ExcelDoc.Application();
                ExcelDoc.Workbook workbook = application.Workbooks.Open(path);
                ExcelDoc.Worksheet worksheet = workbook.ActiveSheet;
                ExcelDoc.Range range = worksheet.UsedRange;
                List<Doc> docs = new List<Doc>();
                for (int row = 2; row < range.Rows.Count; row++)
                {
                    Doc d = new Doc();
                    d.Id = Int32.Parse(((ExcelDoc.Range)range.Cells[row, 1]).Text);
                    d.Name = ((ExcelDoc.Range)range.Cells[row, 2]).Text;
                    d.Price = Decimal.Parse((((ExcelDoc.Range)range.Cells[row, 3]).Text));
                    d.PriceWord = numberToWordConverter(s.Price.ToString());
                    d.Quantity = ((ExcelDoc.Range)range.Cells[row, 4]).Text;
                    docs.Add(d);
                }

                ViewBag.Docs = docs;
                TempData["docs"] = docs;
                return View("Success");

            }

            else
            {

                ViewBag.Error = "File type is incorrect";
                return View("Index");
            }

这是单词导出方法。

      public ActionResult ExportData(int? id)
    {
        var docs = TempData["Docs"] as List<Doc>;
        GridView gv = new GridView();
        gv.DataSource = docs.Where(x=> x.Id == id);
        gv.DataBind();

            Response.ClearContent();
            Response.Buffer = true;
            Response.AddHeader("content-disposition", "attachment; filename=dosya.doc");
            Response.ContentType = "application/vnd.ms-word ";
            Response.Charset = string.Empty;

            StringWriter sw = new StringWriter();
            HtmlTextWriter htw = new HtmlTextWriter(sw);
            gv.RenderControl(htw);
            Response.Output.Write(sw.ToString());
            Response.Flush();
            Response.End();

        return RedirectToAction("Index");
    }

此外，我对下面的部分有疑问。除非我在任务管理器中停止了Excel文件的执行，否则我将收到类似“由于其他进程正在使用它而无法访问”之类的错误消息

   if (System.IO.File.Exists(path))
            {
                System.IO.File.Delete(path);
            }

Answer 1

如果在操作结束时没有关闭文件，则

文件读写操作将不允许其他进程使用。

    workbook.Close(false, Type.Missing, Type.Missing);
    application.Quit();
    ViewBag.Docs = docs;
    TempData["docs"] = docs;
    return View("Success");

替换您的代码

Response.ClearContent();
Response.ContentType = "application/ms-word";
Response.AddHeader("content-disposition", string.Format("attachment;filename={0}.doc", "WordFileName"));
Response.Charset = "";
System.IO.StringWriter stringwriter = new System.IO.StringWriter();
HtmlTextWriter htmlwriter = new HtmlTextWriter(stringwriter);
gv.RenderControl(htmlwriter);
Response.Write(stringwriter.ToString());
Response.End();
