Answer 1

Step 1 is converting from your base64 string to a byte array:

byte[] bytes = Convert.FromBase64String(base64BinaryStr);

Step 2 is saving the byte array to disk:

System.IO.FileStream stream = 
    new FileStream(@"C:\file.pdf", FileMode.CreateNew);
System.IO.BinaryWriter writer = 
    new BinaryWriter(stream);
writer.Write(bytes, 0, bytes.Length);
writer.Close();

Answer 2

using (System.IO.FileStream stream = System.IO.File.Create("c:\\temp\\file.pdf"))
{
    System.Byte[] byteArray = System.Convert.FromBase64String(base64BinaryStr);
    stream.Write(byteArray, 0, byteArray.Length);
}
