vb.net | convert base64Binary to pdf

First convert from your base64 string to a byte array:

 Dim bytes As Byte() = Convert.FromBase64String(base64_string)

Next save the byte array to disk:

Dim stream As System.IO.FileStream = New FileStream("C:\mypdf.pdf", FileMode.CreateNew)
Dim writer As System.IO.BinaryWriter = New BinaryWriter(stream)
writer.Write(bytes, 0, bytes.Length)
