c# byte[] 到string
例子
byte[] b=new byte[]{0x1f,0x1e,0xcc};
用了一个函数 函数.toString(b);
最后输出的是:1f-1e-cc
这个函数是什么函数
但 好像不是 Convert.ToString(b) Convert.ToString(b)输出的是System.Byte[] 展开
其实可以自己写
0x表示是16进制，后面的就是16进制的数字
1f=31；1e=30；cc=204；

将一个包含ASCII编码字符的Byte数组转化为一个完整的String
public static string FromASCIIByteArray(byte[] characters)
{
ASCIIEncoding encoding = new ASCIIEncoding( );
string constructedString = encoding.GetString(characters);
return (constructedString);
}
将一个包含Unicode编码字符的Byte数组转化为一个完整的String：
public static string FromUnicodeByteArray(byte[] characters)
{
UnicodeEncoding encoding = new UnicodeEncoding( );
string constructedString = encoding.GetString(characters);
return (constructedString);
}

char[] c = new char[l * 2];
