字节数组和字符之间互换

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 

   byte[] bt=System.Text.Encoding.Default.GetBytes("字符串");
   
   byte[] bt=Convert.FromBase64String("字符串");

2. 字符串转流

   MemoryStream ms = new MemoryStream(System.Text.Encoding.Default.GetBytes("字符串"));
   
   MemoryStream ms = new MemoryStream(Convert.FromBase64String("字符串"));

3. 流转比特数组

   byte[] bt = ms.ToArray();
   MemoryStream ms = new MemoryStream();
   ms.Write(bt,0,ms.Length);

4. 流转字符串

   string str = Convert.ToBase64String(ms.ToArray());
   
   string str = System.Text.Encoding.Default.GetString(ms.ToArray());

5. 比特数组转字符串

   string str = System.Text.Encoding.Default.GetString(bt);
   string str = Convert.ToBase64String(bt);

6. 比特数组转流

   MemoryStream ms = new MemoryStream(bt);
   MemoryStream ms = new MemoryStream();
   ms.Read(bt,0,bt.Lenght);
