如何判断文件已被完全下载

Question

如题，我想做个积分功能，在文件完全被下载后会扣除积分，请问怎么判断文件已经被完全下载了

Answer 1

开始下载了就要扣分，没下完，下次再下不扣分就是了 就像csdn的下载一样

Answer 2

Response.BufferOutput = False
                Response.Clear()
                Response.AppendHeader("Content-Disposition", "attachment; filename=" & System.IO.Path.GetFileName(fullFileName))
                Response.ContentType = "application/octstream"
                Response.CacheControl = "Private"
                Dim stm As Stream = New FileStream(fullFileName, FileMode.Open, FileAccess.Read, FileShare.Read)                'Stream   stm=new   FileStream(文件路径,FileMode.Open ,FileAccess.Read,FileShare.Read);   
                Response.AppendHeader("Content-length", stm.Length.ToString())
                Dim br As BinaryReader = New BinaryReader(stm)                'BinaryReader   br = new   BinaryReader(stm);  
                Dim bytes As Byte()
                Dim x As Int64
                For x = 0 To (br.BaseStream.Length / 4096)
                    bytes = br.ReadBytes(4096)
                    Response.BinaryWrite(bytes)
                    System.Threading.Thread.Sleep(5)                Next                stm.Close()
有上面的代码后面加扣除积分的代码C#的代码你自己转吧
