我具有ENCRYPT下面的功能。

Public Function Encrypt(ByVal plainText As String) As Byte()

Dim key() As Byte = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24}
Dim iv() As Byte = {65, 110, 68, 26, 69, 178, 200, 219}

    ' Declare a UTF8Encoding object so we may use the GetByte 
    ' method to transform the plainText into a Byte array. 
    Dim utf8encoder As UTF8Encoding = New UTF8Encoding()
    Dim inputInBytes() As Byte = utf8encoder.GetBytes(plainText)

    ' Create a new TripleDES service provider 
    Dim tdesProvider As TripleDESCryptoServiceProvider = New TripleDESCryptoServiceProvider()

    ' The ICryptTransform interface uses the TripleDES 
    ' crypt provider along with encryption key and init vector 
    ' information 
    Dim cryptoTransform As ICryptoTransform = tdesProvider.CreateEncryptor(Me.key, Me.iv)

    ' All cryptographic functions need a stream to output the 
    ' encrypted information. Here we declare a memory stream 
    ' for this purpose. 
    Dim encryptedStream As MemoryStream = New MemoryStream()
    Dim cryptStream As CryptoStream = New CryptoStream(encryptedStream, cryptoTransform, CryptoStreamMode.Write)

    ' Write the encrypted information to the stream. Flush the information 
    ' when done to ensure everything is out of the buffer. 
    cryptStream.Write(inputInBytes, 0, inputInBytes.Length)
    cryptStream.FlushFinalBlock()
    encryptedStream.Position = 0

    ' Read the stream back into a Byte array and return it to the calling 
    ' method. 
    Dim result(encryptedStream.Length - 1) As Byte
    encryptedStream.Read(result, 0, encryptedStream.Length)
    cryptStream.Close()
    Return result
End Function

我如何查看文本的字节值？

解决方案

我们可以使用Encoding类。

要将字节数组转换为字符串，可以使用Encoding.GetString方法

UTF8有一个特殊版本：UTF8Encoding.GetString

如果我们想将加密的字节数组显示为字符串，则不能100％确定要求，那么我会说，不要那样做，因为字符串将不会是"字符串"数据，而是加密的字节并赢得了无法显示(通常)

如果我们问我如何才能将字节值视为字符串...即129,45,24,67等(假设.net 3.5)

string.Join(",", byteArray.Select(b => b.ToString()).ToArray());

并且，如果我们要转换回解密的字节数组，则需要使用与创建原始字节数组相同的编码类，在这种情况下，使用的是UTF8编码类。
