byte[] byteArray = System.Text.Encoding.Default.GetBytes ( str );
反过来，byte[]转成string：
string str = System.Text.Encoding.Default.GetString ( byteArray );
其它编码方式的，如System.Text.UTF8Encoding，System.Text.UnicodeEncoding class等
有时候还有这样一些需求： byte[] 转成原16进制格式的string，例如0xae00cf, 转换成 "ae00cf"；
new byte[]{ 0x30, 0x31}转成"3031": 1 public static string ToHexString(byte[] bytes) // 0xae00cf => "AE00CF " ?
2 {
3 string HexString = string.Empty;
4 if (bytes != null)
5 {
6 StringBuilder builder = new StringBuilder();
7 for (int i = 0; i )
8 {
9 builder.Append(bytes[i].ToString("X2"));
10 }
11 HexString = builder.ToString();
12 }
13 return HexString;
14 }

16 // 把字节型转换成十六进制字符串
17 public static string ByteToString(byte[] InBytes)
18 {
19 string StringOut = "";
20 foreach (byte InByte in InBytes)
21 {
22 StringOut = StringOut + String.Format("{0:X2} ", InByte);
23 }
24 return StringOut;
25 }
26 public string ByteToString(byte[] InBytes, int len)
27 {
28 string StringOut = "";
29 for (int i = 0; i )
30 {
31 StringOut = StringOut + String.Format("{0:X2} ", InBytes[i]);
32 }
33 return StringOut;
34 }
35 // 把十六进制字符串转换成字节型
36 public static byte[] StringToByte(string InString)
37 {
38 string[] ByteStrings;
39 ByteStrings = InString.Split(" ".ToCharArray());
40 byte[] ByteOut;
41 ByteOut = new byte[ByteStrings.Length - 1];
42 for (int i = 0; i == ByteStrings.Length - 1; i++)
43 {
44 ByteOut[i] = Convert.ToByte(("0x" + ByteStrings[i]));
45 }
46 return ByteOut;
47 }

50 //得到十六进制的string数组
51 private static string[] HexToStringArray(byte[] bytes)
52 {
53 string[] strs = new string[bytes.Length];
54
55 for (int i = 0; i )
56 {
57 strs[i] = Convert.ToString(bytes[i], 16);
58 }
59 return strs;
