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窗体中使用哪种返回类型?
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;
}
最佳答案
在ASP.NET Webforms中,您需要手动将文件写入Response流。 Web表单中没有结果抽象。
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();
此代码未经测试,但这应该可以帮助您大致了解。
