定义string变量为str,内存流变量为ms,比特数组为bt 
1.字符串转比特数组 
(1)byte[] bt=System.Text.Encoding.Default.GetBytes("字符串"); 
(2)byte[] bt=Convert.FromBase64String("字符串"); 
2.字符串转流 
(1)MemoryStream ms=new MemoryStream(System.Text.Encoding.Default.GetBytes("字符串")); 
(2)MemoryStream ms=new MemoryStream(Convert.FromBase64String("字符串")); 
3.流转比特数组 
(1)byte[] bt=ms.ToArray(); 
(2)MemoryStream ms=new MemoryStream();ms.Write(bt,0,ms.Length); 
4.流转字符串 
(1)string str=Convert.ToBase64String(ms.ToArray()); 
(2)string str=System.Text.Encoding.Default.GetString(ms.ToArray()); 
5.比特数组转字符串 
(1)string str=System.Text.Encoding.Default.GetString(bt); 
(2)string str=Convert.ToBase64String(bt); 
6.比特数组转流 
(1)MemoryStream ms=new MemoryStream(bt); 
(2)MemoryStream ms=new MemoryStream();ms.Read(bt,0,bt.Lenght);
