C# Asp Net Problem with download in Chrome 12

I have a problem in my project. I have some code for downloading content as: .doc, .zip etc

It was working fine until chrome update for version 12, after that the browser shows an error message: "Download Interrupted".

I already tested in other browsers (Chrome 11, FF and IE8) and everything works fine.

An code sample is:

HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AppendHeader("Content-Type", "application/msword");
HttpContext.Current.Response.AppendHeader("Content-disposition", "attachment; filename=" + filename + ".doc");
HttpContext.Current.Response.AppendHeader("Content-Transfer-Encoding", "binary");
HttpContext.Current.Response.Write(strBody);
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.Close();

Someone know what can be happening or how I can fix that?

Ps. Sorry my english, I'm brazilian :)

Try this:

Response.Buffer = true;
Response.Clear();
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("Content-Disposition", "attachment; filename=yourExcelFileName.xlsx;");
Response.BinaryWrite(yourByteArray);
Response.End();

string applicationName = Session["ApplicationName_UtilityDetail"].ToString();

    HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(Session["DownloadLink_UtilityDetail"].ToString());
    HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
    int bufferSize = 1;
    Response.Clear();
    Response.ClearHeaders();
    Response.ClearContent();
    Response.AppendHeader("Content-Disposition:", "attachment; filename=" + applicationName + ".zip");
    Response.AppendHeader("Content-Length", objResponse.ContentLength.ToString());
    Response.ContentType = "application/download";
    byte[] byteBuffer = new byte[bufferSize + 1];
    MemoryStream memStrm = new MemoryStream(byteBuffer, true);
    Stream strm = objRequest.GetResponse().GetResponseStream();
    byte[] bytes = new byte[bufferSize + 1];
    while (strm.Read(byteBuffer, 0, byteBuffer.Length) > 0)
    {
        Response.BinaryWrite(memStrm.ToArray());
        Response.Flush();
    }
    Response.Close();
    Response.End();
    memStrm.Close();
    memStrm.Dispose();
    strm.Dispose();

I am getting my binary data from sql server database with this code and it is working in all browser;

        DataTable table = SiteFileAccess.GetDataByFileID(fileId);
        byte[] b = (byte[])table.Rows[0]["FileData"];
        Response.Clear();
        Response.AddHeader("Content-Disposition", "attachment; filename=" + table.Rows[0]["FileName"].ToString());
        Response.AddHeader("Content-Length", b.Length.ToString());
        Response.ContentType = "application/octet-stream";
        Response.BinaryWrite(b);
        Response.Flush();
        Response.End();

See the above code and fix it according to your need. Let me know If you need further information

According to an answer in this forum adding Response.End() solved the issue.

In your case, it would be

HttpContext.Current.Response.Write(strBody);
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
HttpContext.Current.Response.Close();
