What about instead of writing whole file content in a single go as
in :
reqStream.Write(inData, 0, rdr.Length)
write chunk data and calculate the amount of data to send per sec :
int totlen = rdr.Length;
'let X be the transfer rate in kb/sec
'then single block size will be :
int chunklen = 1024 * x ;
int pos = 0;
'then send the chunked data :
'Call the following function from a timer event with interval set to
1000 ms , say timer1
void SendChunk(chunklen)
{
int isend = reqStream.Write(_bGetBytesRange(inData, pos, chunklen),
0,chunklen) ;
pos += isend;
if (pos >= totlen ) //verify the logic :)
{
timer1.Stop();
}
}
/* Remember the above code may not be accurate 100% but atleast give u
90% accuracy */.
