How to decode a string of text from a Base64 to a byte array, and the get the string property of this byte array without data corruption

Question

Ok so I have a string of text, encoded in Base 64 like below:

string myText = \"abcBASE64TEXTGOESHEREdef==\";  // actual string is 381 characters long with t         


        

Answer 1

public static string base64Decode(string data)
{
     byte[] toDecodeByte = Convert.FromBase64String(data);

     System.Text.UTF8Encoding encoder = new System.Text.UTF8Encoding();
     System.Text.Decoder utf8Decode = encoder.GetDecoder();

     int charCount = utf8Decode.GetCharCount(toDecodeByte, 0, toDecodeByte.Length);

     char[] decodedChar = new char[charCount];
     utf8Decode.GetChars(toDecodeByte, 0, toDecodeByte.Length, decodedChar, 0);
     string result = new String(decodedChar);
     return result;
}
