FromBase64Trans form truncating string

[Cole Shelton]

Hi all,

I am simply trying to do a transform to a base 64 string and back, but for
some reason, the FromBase64Trans form is return less bytes than it should. I
have verified that the base64 string is the same length as the one that was
output from ToBase64Transfo rm. I also turned on DoNotIgnoreWhit espaces.
Any ideas?? Here is the code:

// ToBase64
ASCIIEncoding enc = new ASCIIEncoding() ;
byte[] valBytes = enc.GetBytes(va l);
MemoryStream mstr = new MemoryStream();

CryptoStream str = new CryptoStream(ms tr,new
ToBase64Transfo rm(),CryptoStre amMode.Write);
str.Write(valBy tes,0,valBytes. Length);

byte[] buf = mstr.ToArray();
return Convert.ToBase6 4String(buf);

// From Base64
byte[] valBytes = Convert.FromBas e64String(val);
MemoryStream mstr = new MemoryStream();

CryptoStream str = new CryptoStream(ms tr,new
FromBase64Trans form(FromBase64 TransformMode.D oNotIgnoreWhite Spaces),CryptoS t
reamMode.Write) ;
str.Write(valBy tes,0,valBytes. Length);

byte[] buf = mstr.ToArray();
ASCIIEncoding enc = new ASCIIEncoding() ;
return enc.GetString(b uf);

If all you want to do is switch back and forth between strings, might
something like this work for you?

public static string ToBase64(string asciiText) {
byte[] buffer = ASCIIEncoding.A SCII.GetBytes(a sciiText);
return Convert.ToBase6 4String(buffer) ;
}

public static string FromBase64(stri ng base64Text) {
byte[] buffer = Convert.FromBas e64String(base6 4Text);
return ASCIIEncoding.A SCII.GetString( buffer);
}

HTH,

Thanks Tim, that worked. I had tried something similar, but got an error.
Must've been doing something wrong.
