Convert a Microsoft Word doc file to HTML file using ASP.NET & C#

Question

How do I convert a Microsoft Word doc file to HTML file using ASP.NET & C#?

Answer 1

Use Microsoft Word's built-in functionality - "File > Save as Web Page..."

Or, to do this programmatically, use the _Document.SaveAs method in the Microsoft.Office.Interop.Word namespace.

 protected void Button1_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile)
{
// When we click Button1, the file we specify is uploaded to a temporary
// folder, then converted into an html document...
string folder_to_save_in = @"c:\temp\documents\";
string filePath = folder_to_save_in + FileUpload1.FileName;
// This bit does the actual file upload:
FileUpload1.SaveAs(filePath);

// Here we set up a WOrd Application...
Word.ApplicationClass wordApplication = new Word.ApplicationClass();

// Opening a Word doc requires many parameters, but we leave most of them blank...
object o_nullobject = System.Reflection.Missing.Value;
object o_filePath = filePath;
Word.Document doc = wordApplication.Documents.Open(ref o_filePath,
ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject,
ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject,
ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject);

// Here we save it in html format...
// This assumes it was called "something.doc"
string newfilename = folder_to_save_in + FileUpload1.FileName.Replace(".doc", ".html");
object o_newfilename = newfilename;
object o_format = Word.WdSaveFormat.wdFormatHTML;
object o_encoding = Microsoft.Office.Core.MsoEncoding.msoEncodingUTF8;
object o_endings = Word.WdLineEndingType.wdCRLF;
// Once again, we leave many of the parameters blank.
// See http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbawd11/html/womthSaveAs1_HV05213080.asp
// for full list of parameters.
wordApplication.ActiveDocument.SaveAs(ref o_newfilename, ref o_format, ref o_nullobject,
ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject,
ref o_nullobject, ref o_nullobject, ref o_encoding, ref o_nullobject,
ref o_nullobject, ref o_endings, ref o_nullobject);

// Report success...
Label1.Text = "Uploaded successfully!";
// Finally, close original...
doc.Close(ref o_nullobject, ref o_nullobject, ref o_nullobject);
}
}
