How to convert byte array to string

I created a byte array with two strings. How do I convert a byte array to string?

var binWriter = new BinaryWriter(new MemoryStream());
binWriter.Write("value1");
binWriter.Write("value2");
binWriter.Seek(0, SeekOrigin.Begin);

byte[] result = reader.ReadBytes((int)binWriter.BaseStream.Length);

I want to convert result to a string. I could do it using BinaryReader, but I cannot use BinaryReader (it is not supported).
