c#之字符串与字节数组互转

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);
