C金沙官网线上# 字符串和字节数组转换

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

金沙官网线上,(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);

 

对应

string s = "base64字符串与普通字符串互转";
byte[] bb = System.Text.Encoding.Default.GetBytes(s);
//转成 Base64 形式的 System.String
string sss = Convert.ToBase64String(bb);
byte[] c = Convert.FromBase64String(sss);
string d = System.Text.Encoding.Default.GetString(c);

 

总结:

字符串、字节数组、内存流的转换关系如下图:

下图增加了Base64String的转换:

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

(2)MemoryStream ms=new MemoryStream(Convert.FromBase64String("字符串"));

(1)byte[] bt=ms.ToArray();

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

1.字符串转比特数组

(2)string str=Convert.ToBase64String(bt);
