convert string[] to base64

I am opening a file encoded in base64 and I need to decode it

string[] lines = File.ReadAllLines(open1.FileName);

is there anyway to do this? I have tried doing this.

string[] lines = File.ReadAllLines(Convert.ToBase64String(open1.FileName));

you question is not clear

if you want to convert string[] to array of base64 you can do this :

public static string[] ToBase64(string[] text)
{
    var encodedArray = new string[text.Length];

    for (var index = 0; index < text.Length; index++)
    {
        var line = text[index];
        var encoded = Convert.ToBase64String(Encoding.UTF8.GetBytes(line));
        encodedArray[index] = encoded;
    }
    return encodedArray;
}

this returns your array with each line encoded in base64. and to reverse it :

public static string[] ToString(string[] encodedString)
{
    var decodedArray = new string[encodedString.Length];
    for (var i = 0; i < encodedString.Length; i++)
    {
        var line = encodedString[i];
        var decoded = Convert.FromBase64String(line);
        decodedArray[i] = Encoding.UTF8.GetString(decoded);
    }

    return decodedArray;
}
