我正在使用FileResult作为MVC中返回PDF文件的函数的返回值.
我应该在Web窗体中使用什么返回类型？
谢谢
public FileResult PrintPDFVoucher(object sender,EventArgs e)
{
PdfDocument outputDoc = new PdfDocument();
PdfDocument pdfDoc = PdfReader.Open(
Server.MapPath(ConfigurationManager.AppSettings["Template"]),PdfDocumentOpenMode.Import
);
MemoryStream memory = new MemoryStream();
try
{
//Add pages to the import document
int pageCount = pdfDoc.PageCount;
for (int i = 0; i < pageCount; i++)
{
PdfPage page = pdfDoc.Pages[i];
outputDoc.AddPage(page);
}
//Target specifix page
PdfPage pdfPage = outputDoc.Pages[0];
XGraphics gfxs = XGraphics.FromPdfPage(pdfPage);
XFont bodyFont = new XFont("Arial",10,XFontStyle.Regular);
//Save
outputDoc.Save(memory,true);
gfxs.Dispose();
pdfPage.Close();
}
finally
{
outputDoc.Close();
outputDoc.Dispose();
}
var result = new FileContentResult(memory.GetBuffer(),"text/pdf");
result.FileDownloadName = "file.pdf";
return result;
}
解决方法
在ASP.NET Webforms中,您需要手动将文件写入Response流. webforms中没有结果抽象.
Response.ContentType = "Application/pdf"; //Write the generated file directly to the response stream Response.BinaryWrite(memory);//Response.WriteFile(FilePath); if you have a physical file you want them to download Response.End();
此代码未经过测试,但这应该可以帮助您完成大方向.
