i am trying to pdf generate using html template in mvc4 and i have adding xmlworker packages and write a following code. i will build my solution then show in following error. XMLWorkerHelper does not contain a constructor that takes 0 arguments Please suggest me... Controller:-
public void abcd()
{
try
{
string UniqueNumber = Request.QueryString["UniqueNumber"];
string strFileName = UniqueNumber;
string strFileExtension = ".pdf";
string strContentType = FileManager.FileContentType_application_pdf;
string strExportData = string.Empty;
Document pdfDoc = new Document(PageSize.A4, 43f, 50f, 5f, 50f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
var output = new MemoryStream();
StringWriter sw = new StringWriter();
XMLWorkerHelper htw = new XMLWorkerHelper();
StringReader sr;
sr = new StringReader(Convert.ToString(ExportData.UserDetails(UniqueNumber)));
PdfWriter.GetInstance(pdfDoc, output);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
strFileName = strFileName.Replace(" - ", "-").Replace(" ", "-").Replace("--", "-");
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", string.Format("attachment; filename={0}{1}", strFileName, strFileExtension));
Response.ContentType = strContentType;
Response.Charset = "";
Response.BinaryWrite(output.ToArray());
Response.Flush();
Response.End();
}
catch (Exception ex)
{
//
}
}
It looks like the Singleton pattern is used within this assembly Dip.
Please replace your current code, XMLWorkerHelper htw = new XMLWorkerHelper();
with this XMLWorkerHelper htw = XMLWorkerHelper.GetInstance();
and give it a shot.
As a side note, you may want to look into the IDisposable interface. Check if any of the objects your are "newing" up implement it and dispose of them.
