字符串string、内存流Memory、Stream 流 及比特数组byte[] 互转方法汇总

字符串string和内存流MemoryStream及比特数组byte[]互转比较
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);可以看出byte[]比较活跃在string和流转化时是个重要的桥梁
