Export data from an asp.net page to an Excel file and I’m basically just outputting HTML to the XLS file where I want to embed an image. The image file has to be in binary form in the content.

I have to get images in StringWriter and use System.Text.Encoding.ASCII.GetBytes(stringwriter string) in an array of bytes. then write these as outputStream.Write(byte_array, 0, byte_array.Length); where outputstream is HttpContext Response outputstream.


string filePath = Server.MapPath(lblReportLogo.Text);
System.Drawing.Image imgPhoto = System.Drawing.Image.FromFile(filePath);
string imagepath = string.Format("<img src='{0}' width='{1}' height='{2}'/>", filePath, 100, 40);
String headerTable = @"<div style='text-align:center'>"+  imagepath +"</div>";
Response.Write(headerTable);
imgPhoto.Dispose();
