here is code

 HttpWebRequest req = (HttpWebRequest)WebRequest.Create(uploadUrl);

        req.Method = "PUT";
        req.AllowWriteStreamBuffering = true;

        // Retrieve request stream and wrap in StreamWriter
        Stream reqStream = req.GetRequestStream();
        StreamWriter wrtr = new StreamWriter(reqStream);

        // Open the local file
        StreamReader rdr = new StreamReader(localFile);

        // loop through the local file reading each line 

        char[] buff = new char[1024];
        int inLine = rdr.Read(buff, 0, 1024);
        //int inLine = rdr.ReadBlock (buff,0,1024);
        while (inLine > 0)
        {
            wrtr.WriteLine (buff);

           inLine = rdr.Read (buff, 0, 1024);
        }

        rdr.Close();
        wrtr.Close();

        try
        {
      开发者_运维问答      req.GetResponse();
        }
        catch
        {

        }
        reqStream.Close();

Thanks

The first problem I see is that you're always writing the entire contents of 'buff', not just the number of bytes read. Unless you file size is evenly divisible by 1024 that's a problem. It's also a problem in the even the read doesn't bring back a full 1024 bytes.

THe second thing I question here is why are you using a char[] for holding binary data? That's just a bad practice all around. char is for string data (and char in CE is 2 bytes anyway). Use a byte[] for binary data - that's what it's for. It's quite possible that the current encoding is doing something like stripping the MSB off of data bytes because you're stuffing it into a char. It could also have to do with the size issue.
