如何使用mvc c#将jpg / png / txt或任何文件格式转换为pdf。 这是代码:
public ActionResult SaveProfileDocument(string code)
{
bool isSavedSuccessfully = true;
string fName = "";
string _documentname = String.Empty;
try
{
foreach (string fileName in Request.Files)
{
HttpPostedFileBase file = Request.Files[fileName];
//Save file content goes here
fName = file.FileName;
if (file != null && file.ContentLength > 0)
{
var originalDirectory = new DirectoryInfo(string.Format("{0}Documents\\Profile\\" + code, Server.MapPath(@"\")));
string pathString = System.IO.Path.Combine(originalDirectory.ToString());
var fileName1 = Path.GetFileName(file.FileName);
bool isExists = System.IO.Directory.Exists(pathString);
if (!isExists)
System.IO.Directory.CreateDirectory(pathString);
_documentname=fName;
var path = string.Format("{0}\\{1}", pathString, file.FileName);
if (System.IO.File.Exists(path)) {
_documentname=Guid.NewGuid()+"_"+file.FileName;
var path2 = string.Format("{0}\\{1}", pathString,_documentname );
file.SaveAs(path2);
}
else {
file.SaveAs(path);
}
}
}
}
catch (Exception ex)
{
isSavedSuccessfully = false;
}
if (isSavedSuccessfully)
{
return Json(new { Message = fName, documentname = _documentname });
}
else
{
return Json(new { Message = "Error in saving file", documentname=""});
}
}
在上面的代码中,我正在保存文件。但是 在这里我需要转换文件然后保存。
所以对于转换我需要一个单独的类或方法,这里只调用该方法。
事情是,在上传文件时,需要将pdf转换为任何文件以转换为pdf。并保存在文件夹或其他任何内容中。

无法将图片文件转换为PDF格式。您可以创建PDF文件并将图像文件添加到其中:
string pdfpath = Server.MapPath("PDFs");
string imagepath = Server.MapPath("Images");
Document doc = new Document();
try
{
PdfWriter.GetInstance(doc, new FileStream(pdfpath + "/Images.pdf", FileMode.Create));
doc.Open();
doc.Add(new Paragraph("GIF"));
Image gif = Image.GetInstance(imagepath + "/mikesdotnetting.gif");
doc.Add(gif);
}
catch (Exception ex)
{
//Log error;
}
finally
{
doc.Close();
}
