Answer 1

protected void Upload(object sender, EventArgs e)
{
object missingType = Type.Missing;
object readOnly = true;
object isVisible = false;
object documentFormat = 8;
string randomName = DateTime.Now.Ticks.ToString();
object htmlFilePath = Server.MapPath("~/Temp/") + randomName + ".htm";
string directoryPath = Server.MapPath("~/Temp/") + randomName + "_files";

//Upload the word document and save to Temp folder
FileUpload1.SaveAs(Server.MapPath("~/Temp/") + Path.GetFileName(FileUpload1.PostedFile.FileName));
object fileName = FileUpload1.PostedFile.FileName;

//Open the word document in background
ApplicationClass applicationclass = new ApplicationClass();
applicationclass.Documents.Open(ref fileName,
ref readOnly,
ref missingType, ref missingType, ref missingType,
ref missingType, ref missingType, ref missingType,
ref missingType, ref missingType, ref isVisible,
ref missingType, ref missingType, ref missingType,
ref missingType, ref missingType);
applicationclass.Visible = false;
Document document = applicationclass.ActiveDocument;

//Save the word document as HTML file
document.SaveAs(ref htmlFilePath, ref documentFormat, ref missingType,
ref missingType, ref missingType, ref missingType,
ref missingType, ref missingType, ref missingType,
ref missingType, ref missingType, ref missingType,
ref missingType, ref missingType, ref missingType,
ref missingType);

//Close the word document
document.Close(ref missingType, ref missingType, ref missingType);

//Delete the Uploaded Word File
File.Delete(Server.MapPath("~/Temp/") + Path.GetFileName(FileUpload1.PostedFile.FileName));

//Read the Html File as Byte Array and Display it on browser
byte[] bytes;
using (FileStream fs = new FileStream(htmlFilePath.ToString(), FileMode.Open, FileAccess.Read))
{
BinaryReader reader = new BinaryReader(fs);
bytes = reader.ReadBytes((int)fs.Length);
fs.Close();
}
Response.BinaryWrite(bytes);
Response.Flush();

//Delete the Html File
File.Delete(htmlFilePath.ToString());
foreach (string file in Directory.GetFiles(directoryPath))
{
File.Delete(file);
}
Directory.Delete(directoryPath);
Response.End();
}
