You can write excel file to response HttpResponse.WriteFile Method

string CurrentDate;
DateTime saveNow = DateTime.Now;
CurrentDate = saveNow.Date.ToShortDateString();
string reportContent = prepareHTM();

string pathFile = Environment.GetFolderPath(Environment.SpecialFolder.CommonDesktopDirectory) + "\\As_Build_Report_ "+ CurrentDate + ".html";

using (StreamWriter outfile = new StreamWriter(pathFile, true))
{
    outfile.WriteLine(reportContent);
}

System.IO.FileInfo file = new System.IO.FileInfo(pathFile); 
Response.Clear(); 
Response.Charset="UTF-8"; 
Response.ContentEncoding=System.Text.Encoding.UTF8; 
Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name); 
Response.AddHeader("Content-Length", file.Length.ToString());    
Response.ContentType = "application/ms-excel";  
Response.WriteFile(file.FullName); 
Response.End();
