I have a File (xfdl) that is encoded base64 and compressed using gzip. When I open the File with Notepad I can read the first line.
application/vnd.xfdl;content-encoding="base64-gzip"
Is there a Lib (free if possible) that I can Use from VB.NET to gzip/gunzip Files? and Encode/Decode Base64?

To gzip/gunzip (a free library):
http://www.icsharpcode.net/OpenSource/SharpZipLib/

To Encode/Decode Base64 (code below):


        public string Encode(string str)
        {
            byte[] encbuff = System.Text.Encoding.UTF8.GetBytes(str);
            return Convert.ToBase64String(encbuff);
        }
        public string Decode(string str)
        {
            byte[] decbuff = Convert.FromBase64String(str);
            return System.Text.Encoding.UTF8.GetString(decbuff);
        }

Sorry thought I was in the C# section..
Here is the code to Encode/Decode Base64 in VB.NET:

    Public Function Encode(ByVal str As String) As String
        Dim encbuff As Byte() = System.Text.Encoding.UTF8.GetBytes(str)
        Return (Convert.ToBase64String(encbuff))
    End Function
 
    Public Function Decode(ByVal str As String) As String
        Dim decbuff As Byte() = Convert.FromBase64String(str)
        Return (System.Text.Encoding.UTF8.GetString(decbuff))
    End Function
