C#字符串string和内存流MemoryStream及比特数组byte[]

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
