I'm using sendgrid to send mails with attachments. But seems like excel file is corrupted in the mail. This is the code I'm using
byte[] byteData = System.Text.Encoding.ASCII.GetBytes(File.ReadAllText(#"fullpath\test.xlsx"));
msg.Attachments = new List<SendGrid.Helpers.Mail.Attachment>
{
new SendGrid.Helpers.Mail.Attachment
{
Content = Convert.ToBase64String(byteData),
Filename = "test.xlsx",
Type = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
Disposition = "attachment"
}
};
On opening of excel file, I'm getting a popup "We found a problem with content...If you trust click "Yes". On Yes, Excel cannot open this file. Can anyone please help me on this

I think the issue may be that you are getting the byte data by reading the file as text and then converting that text to bytes through the lens of ASCII encoding. It may work better to just read the file as bytes initially.
Try:
byte[] byteData = File.ReadAllBytes(#"fullpath\test.xlsx");
msg.Attachments = new List<SendGrid.Helpers.Mail.Attachment>
{
new SendGrid.Helpers.Mail.Attachment
{
Content = Convert.ToBase64String(byteData),
Filename = "test.xlsx",
Type = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
Disposition = "attachment"
}
};
Try below
msg.AddAttachment("test.xlsx"); // Physical file path
Make assure file path is relevant
or You try with Bytes as well,
var bytes = File.ReadAllBytes(filePath);
var file = Convert.ToBase64String(bytes);
msg.AddAttachment("Name.xls", file);
I already have the path of the Excel file, but whenever I call save method, the program writes new content to UTC.xlsx file.
string pathString = "C:\Users\ADMIN-PC\Documents\SUMMER 2018\PRN192\CreateFile\SubFolder\UTC.xlsx";
ef.Save(pathString);
var path = #"C:\Users\ADMIN-PC\Documents\SUMMER 2018\PRN192\CreateFile\SubFolder\UTC.xlsx";
// Load the workbook:
var workbook = ExcelFile.Load(path);
// Manipulate the workbook …
// … and save it over the original
workbook.Save(path);
I try to create a PDF/A-3b file which contains an embedded XML-File to be ZUGFeRD conform. I use Perl and PDFLib for this purpose. The PDFLib Documentation out there is just for Java and PHP. Creating the PDF works fine, but the XML part is my problem.
So how can i create a pvf from xml and join this to my pdf?
This is what PDFLib recommends in Java:
// Place XML stream in a virtual PVF file
String pvf_name = "/pvf/ZUGFeRD-invoice.xml";
byte[] xml_bytes = xml_string.getBytes("UTF-8");
p.create_pvf(pvf_name, xml_bytes, "");
// Create file attachment (asset) from PVF file
int xml_asset = p.load_asset("Attachment", pvf_name,
"mimetype=text/xml description={ZUGFeRD invoice in XML format} "
+ "relationship=Alternative documentattachment=true");
// Associate file attachment with the document
p.end_document("associatedfiles={" + xml_asset + "}");
So I thought, take the example and fit it to perl:
my $xmldata = read_file($xmlfile, binmode => ':utf8'); #I use example xml at the moment
my $pvf_xml = "/pvf/ZUGFeRD-invoice.xml";
PDF_create_pvf($pdf, $pvf_xml, $xmldata, ""); #because no OOP i need to call it this way (works with all other PDF Functions)
my $xml_invoice = PDF_load_asset("Attachment", $pvf_xml, "mimetype=text/xml "
."description={Rechnungsdaten im Zugferd-Xml-Format} "
."relationship=Alternative documentattachment=true");
PDF_end_document($pdf, "associatedfiles={".$xml_invoice."}");
In PHP examples it's also not needed to convert to ByteArray after reading xml. Further tried it with unpack but don't seem to be the problem.
If I call my script I'm just getting:
Usage: load_asset(type, filename, optlist); at signatur_test.pl line
41.
I think the problem is that pvf_xml isn't created the line before.
Anyone did this before and no how to solve this?
Arg, i was just missing the PDF-Handle in the load_asset method:
my $xml_invoice = PDF_load_asset($pdf, "Attachment", $pvf_xml, "mimetype=text/xml "
."description={Rechnungsdaten im Zugferd-Xml-Format} "
."relationship=Alternative documentattachment=true");
This way it works.
I need to sort some Russian text file and when I try to read the strings and print them out, they all appear garbled and like boxes. Looks like there is no Russian support for my eclipse. I downloaded Language packs plug in but I can't figure out how to install it.
Help required please.
FileInputStream fstream = new FileInputStream("c:\\textfile.txt");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
ArrayList<String> allLines = new ArrayList<String>();
//Read File Line By Line
while ((strLine = br.readLine()) != null) {
allLines.add(strLine);
System.out.println(strLine);
}
How can you be sure it's an eclipse problem? It could be:
The encoding of the text file
The method you used to read the text file (eg: InputStreamReader uses default charset unless you explicitly specify it on the constructor)
The method you used to store the text file in memory
The method you used to print the text
The method you used to view the printed text
I've got an Excel file that's built using OpenXML 2 and I want to send it as an email attachment. e.g.
System.IO.MemoryStream stream = new System.IO.MemoryStream();
SpreadsheetDocument package = SpreadsheetDocument.Create(stream, SpreadsheetDocumentType.Workbook))
AddParts(package); //created using document reflector
Saving the spreadsheet to a temp file using
stream.WriteTo(new System.IO.FileStream(#"c:\test.xlsx", System.IO.FileMode.Create));
works fine. But trying to send the stream directly as an email attachment fails - just get an empty file attached to the email when I do
System.Net.Mail.Attachment file = new System.Net.Mail.Attachment(stream, "MobileBill.xlsx", "application/vnd.ms-excel");
Anbody know how to do this?
Ok, I got this working, though through some effort. To create the stream:
MemoryStream stream = new MemoryStream();
using (SpreadsheetDocument package = SpreadsheetDocument.Create(stream, SpreadsheetDocumentType.Workbook))
{
Excel.CreateSpreadsheet(package, Excel_Methods.CreateSpotQuoteOut(), true);
}
stream.Seek(0, SeekOrigin.Begin);
System.Net.Mail.Attachment attach = new System.Net.Mail.Attachment(stream, "spreadsheet.xlsx");
attach.ContentDisposition.CreationDate = DateTime.Now;
attach.ContentDisposition.ModificationDate = DateTime.Now;
attach.ContentDisposition.Inline = false;
attach.ContentDisposition.Size = stream.Length;
attach.ContentType.MediaType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Also, I found that mine were not being sent right after I created them, and the reason for that is "standalone=yes" was not being added to the xml declaration of all the pages, so in my AddParts function, after adding the parts, I passed them into this function:
private static void AddXMLStandalone(OpenXmlPart part)
{
System.IO.StreamWriter writer = new System.IO.StreamWriter(part.GetStream());
XmlDocument doc = new XmlDocument();
doc.Load(part.GetStream());
doc.InnerXml = doc.InnerXml.Substring(doc.InnerXml.IndexOf("?>") + 2);
doc.InnerXml = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>" + doc.InnerXml;
part.GetStream().SetLength(doc.InnerXml.Length);
doc.Save(writer);
writer.Flush();
writer.Close();
}
Good luck!
do this:
System.Net.Mail.Attachment file = new System.Net.Mail.Attachment(new MemoryStream(stream.ToArray()), "MobileBill.xlsx", "application/vnd.ms-excel");
Apparently the memory stream doesn't get flushed or something
For your "content unreadable" problem, make sure to Save() your Workbooks and Worksheets and enclose your SpreadsheetDocument in a using statement to ensure all packages and zipped streams are flushed, closed and so on.
System.IO.MemoryStream stream = new System.IO.MemoryStream();
using (SpreadsheetDocument package = SpreadsheetDocument.Create(stream, SpreadsheetDocumentType.Workbook)))
{
AddParts(package);
//Save if AddParts hasn't done it
}
System.Net.Mail.Attachment file = ...
Thinking out load: could it be, that the Attachment class expects to read from the current possition in the provided stream? If this is the case, you would probably have to "seek" back to the beginning of the stream, before feeding it to the Attachment constructor:
AddParts(package); //created using document reflector
stream.Seek(0, SeekOrigin.Begin);
System.Net.Mail.Attachment file = new System.Net.Mail.Attachment(stream, "MobileBill.xlsx", "application/vnd.ms-excel");
