{
byte [] Content = FileToByteArray（filename）;
Response.ContentType =application / pdf;
Response.AddHeader（Content -Disposition，inline; filename = mssql2005-feature-comparison.pdf＃toolbar = 0）;
Response.BinaryWrite（Content）;
Response.End（ ）;

尝试
{
//打开文件阅读
System.IO.FileStream _FileStream = new System.IO.FileStream（_FileName，System.IO.FileMode.Open，System.IO。的FileAccess 。读取）;
//将文件流附加到二进制阅读器
System.IO.BinaryReader _BinaryReader = new System.IO.BinaryReader（_FileStream ）;
//获取文件的总字节长度
long _TotalBytes = new System.IO.FileInfo（_FileName）.Length;
//将整个文件读入缓冲区
_Buffer = _BinaryReader.ReadBytes（（Int32）_TotalBytes）;
//System.IO.BinaryWriter _BinaryWriter = new System.IO.BinaryWriter（_FileStream）;
//关闭文件阅读器
_FileStream.Close（）;
_FileStream.Dispose（）;
_BinaryReader.Close（）;
}
catch（异常_Exception）
{
//错误
Console.WriteLine（异常陷入过程中：{0} ，_ Exception.ToString（））;
}
返回_Buffer;

试试这个很好的工作
try this it's woring perfectly
Response.ContentType = "application/pdf";
Context.Response.AppendHeader("Content-Disposition","inline; filename=foo.pdf");
