I'm trying to encode some strings back and forth from base-64 string and I'm having truble to get the right result.

string text = base64string.... //Here I have a base-64 string.
byte[] encodedByte = System.Text.ASCIIEncoding.ASCII.GetBytes(text);
string base64Encoded = Convert.ToBase64String(encodedByte);

if (text == base64Encoded) //If the new encoded string is equal to its original value
    return base64Encoded;

I have tried my ways to do this and I don't seem to get the right result. I have tried both with System.Text.Encoding.Unicode and System.Text.Encoding.UTF8

What could be the problem? Does anyone have a proper solution?
