How to convert a byte array to a string?

Question

Using the function from: http://msdn.microsoft.com/en-us/library/system.security.cryptography.rijndaelmanaged.aspx

public static byte[] encryptStringToBytes_AES(string plainText, byte[] Key, byte[] IV)

As you can see it returns a byte array, I want to convert the byte array to a string.

How can I convert it from a byte array to string and visa versa?

Answer 1

If you don't care how it's stored, an easy way is to use:

Convert byte array into string: Convert.ToBase64String(YourByteArray) and
Convert string into byte array: Convert.FromBase64String(YourString).
This will give a concise, printable ASCII representation of the byte array.

Answer 2

While using Rijndael Encryption i faced this problem, it returns encrypted byte[] (array), Convert byte[] to string;

 myStringVariable= Convert.ToBase64String(myEncryptedByteArray);  

Convert string to byte[];

byte[] bytes = Convert.FromBase64String(myStringVariable);
