还有一个类UnicodeEncoding，使用起来非常简单:

ByteConverter = new UnicodeEncoding();
string stringDataForEncoding = "My Secret Data!";
byte[] dataEncoded = ByteConverter.GetBytes(stringDataForEncoding);

Console.WriteLine("Data after decoding: {0}", ByteConverter.GetString(dataEncoded));

string result = ASCIIEncoding.UTF8.GetString(byteArray);

还有一个类UnicodeEncoding，使用起来非常简单:

ByteConverter = new UnicodeEncoding();
string stringDataForEncoding = "My Secret Data!";
byte[] dataEncoded = ByteConverter.GetBytes(stringDataForEncoding);

Console.WriteLine("Data after decoding: {0}", ByteConverter.GetString(dataEncoded));

至少有四种不同的转换方式。

Encoding's GetString, but you won't be able to get the original bytes back if those bytes have non-ASCII characters. BitConverter.ToString The output is a "-" delimited string, but there's no .NET built-in method to convert the string back to byte array. Convert.ToBase64String You can easily convert the output string back to byte array by using Convert.FromBase64String. Note: The output string could contain '+', '/' and '='. If you want to use the string in a URL, you need to explicitly encode it. HttpServerUtility.UrlTokenEncodeYou can easily convert the output string back to byte array by using HttpServerUtility.UrlTokenDecode. The output string is already URL friendly! The downside is it needs System.Web assembly if your project is not a web project.

完整的例子:

byte[] bytes = { 130, 200, 234, 23 }; // A byte array contains non-ASCII (or non-readable) characters

string s1 = Encoding.UTF8.GetString(bytes); // ���
byte[] decBytes1 = Encoding.UTF8.GetBytes(s1);  // decBytes1.Length == 10 !!
// decBytes1 not same as bytes
// Using UTF-8 or other Encoding object will get similar results

string s2 = BitConverter.ToString(bytes);   // 82-C8-EA-17
String[] tempAry = s2.Split('-');
byte[] decBytes2 = new byte[tempAry.Length];
for (int i = 0; i < tempAry.Length; i++)
    decBytes2[i] = Convert.ToByte(tempAry[i], 16);
// decBytes2 same as bytes

string s3 = Convert.ToBase64String(bytes);  // gsjqFw==
byte[] decByte3 = Convert.FromBase64String(s3);
// decByte3 same as bytes

string s4 = HttpServerUtility.UrlTokenEncode(bytes);    // gsjqFw2
byte[] decBytes4 = HttpServerUtility.UrlTokenDecode(s4);
// decBytes4 same as bytes

BitConverter类可用于将字节[]转换为字符串。

var convertedString = BitConverter.ToString(byteAttay);

BitConverter类的文档可以在MSDN上打印。

string result = System.Text.Encoding.UTF8.GetString(byteArray);
