.net (vb or c#) file transfer problems

Here is the paste bin of my code: http://pastebin.com/m5b4d4d85

Here is the problem:
1 - im trying to make it so I can transfer large files. I have it now to the point it "thinks" its sending the large file but its always corrupt do to sending to many bytes. It seems when I change the "Dim blocksize As Int16 = 1000" to a different number such as 8000 it either gets it closer to the right file size or farther away if that makes sense. So have to figure out why its doing that.

2 - testing on a small file 1kb zip file. When it transfers it, I can open it up and view my text file inside the zip and everything works fine except that the transfered zip is now 3kb not 1kb like the original. So have to figure this out as well dont make sense to me.

Im new to this networking stuff so bare with me as this code is probably "gross" but any help would be greatly appreciated.

Thank You!

Here is your problem:

thisread = fileStream.Read(dataByte, 0, blocksize)
networkStream.Write(dataByte, 0, dataByte.Length)

The Read method returns the number of bytes read. You ignore this value and just write the entire content of the buffer regardless of how much of the buffer was actually used.

Change if to only write the actual data that you got:

thisread = fileStream.Read(dataByte, 0, blocksize)
If thisread > 0 Then
   networkStream.Write(dataByte, 0, thisread)
End If
