Base64 encode a Unicode string as a string
<source lang="csharp">using System; using System.IO; using System.Text; class MainClass {
public static void Main()
{
byte[] b = Encoding.Unicode.GetBytes("string");
// Return the Base64-encoded string.
string str = Convert.ToBase64String(b);
Console.WriteLine(str);
Convert.FromBase64String(str);
// Return the decoded Unicode string.
Console.WriteLine(Encoding.Unicode.GetString(b));
}
}</source>

Decode the Base64-encoded int to a byte array
<source lang="csharp">using System; using System.IO; using System.Text; class MainClass {

Encode int to the Base64-encoded byte array

// Return the Base64-encoded int.
string str = Convert.ToBase64String(b);
Console.WriteLine(str);
b = Convert.FromBase64String(str);
// Return the decoded int.
int i = BitConverter.ToInt32(b,0);
Console.WriteLine(i);
}
