Hi to all,

I have many PDF documents in binary format, which is in the SQL Server 2008 database.
I have a gridview in my ASP.Net page.
When a user clicks on any ID column of the record I need to open the pdf in the browser.

Are there any free online PDF viewer controls out there?
How can I convert the binary PDF file and display as PDF in the browser using c#?

推荐答案

您不需要将其转换为PDF，它已经是.您只需要发送二进制流.

You don''t need to convert it to a PDF, it already is. You just need to send the binary stream.

private void SendDocument(byte[] buf)
{
    HttpContext.Current.Response.Clear();
    HttpContext.Current.Response.ClearHeaders();
    HttpContext.Current.Response.ClearContent();
    HttpContext.Current.Response.ContentType = "Application/pdf";

    HttpContext.Current.Response.AppendHeader("Content-Length", buf.Length.ToString());
    HttpContext.Current.Response.BinaryWrite(buf);

    HttpContext.Current.Response.End();
}
