Question

What is wrong with the following code?

        Stream inputstream = File.Open("e:\\read.txt", FileMode.Open);
        Stream writestream = File.Open("e:\\write.txt", FileMode.OpenOrCreate);

        do
        {
            writestream.WriteByte((byte)inputstream.ReadByte());
        }
        while (inputstream.ReadByte() != -1);

read.txt has “the quick brown fox jumped over the lazy dog.”

Whereas the write.txt file contains few contents skimmed “teqikbonfxjme vrtelz o.”

Answer 1

You’re only writing every other byte because you’re consuming one in the while check.
