File streaming in .NET

Hello All

Today i will focus on simple file steaming in .NET which I have to implement it in one of my project.Though it’s not optimize but its OK for serve small purpose.

In the project I have to read a PDF file from the server and with FileStream and Flash it with Response to the client side.

the code is as bellow.

private void generateRequestedPDF()
{
    try
    {
        string file = Path.GetFileName(Request.QueryString["RefID"]);// get file name from query string.use your custom method." 

        FileStream fileStream = new FileStream(Server.MapPath(@"~\uploadedFiles\" + file), FileMode.Open);
        long fileSize = fileStream.Length;

        byte[] buffer = new byte[(int)fileSize];
        fileStream.Read(buffer, 0, (int)fileSize);
        fileStream.Close();

        Response.Clear();

        Response.ContentType = "Application/pdf";// use your custom type"
        Response.AddHeader("Content-Disposition", "inline; filename=" + file);

        Response.OutputStream.Write(buffer, 0, (int)fileSize);
        Response.Flush();
        Response.Close();
    }
    catch (Exception exc)
    {
    //  throw exc;
        this.writeLogWarn(exc);
        Response.Redirect("~/Pages/Content/TechCorner.aspx");
    }
   
}

thats all for today.
