I am working on WCF service to create a pad file and want to set image on created pdf. Below is my code. it gives me error "object reference not set to an object instance"
string str = System.Web.HttpContext.Current.Request.MapPath("App_Data/suc.png");
Image imgCheckBoxChecked = Image.GetInstance(str);
The other thing I try and it gives me error :Could not find file 'C:\\Program Files\\Common Files\\Microsoft Shared\\DevServer\\10.0\\suc.png: Below is my other code
Image imgCheckBoxChecked = Image.GetInstance("App_Data/suc.png");
cell.AddElement(imgCheckBoxChecked);
cell.Colspan = 4;
table.AddCell(cell);
Any idea on how to solve this error and set image on pdf. Thanks
您可以使用AppDomain.BaseDirectory
来获取主dll的目录,此后,您可以使用它来获取映像dll的路径,例如Path.Combine(AppDomain.BaseDirectory, "App_Data\\\\suc.png")
,如果您ASP.NET中的主机服务,并且dll在Bin
目录中,您可以使用相对路径,例如Path.Combine(AppDomain.BaseDirectory, "..\\\\App_Data\\\\suc.png")
string pdfPath = "~/PDF/File_1.pdf";
iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(Server.MapPath("~/image.JPG"));
img.ScalePercent(100f);
Document doc = new Document();
PdfWriter.GetInstance(doc, new FileStream(Server.MapPath(pdfPath), FileMode.Create));
doc.Open();
doc.Add(new Paragraph(sb.ToString()));
doc.Add(img);
doc.Close();
