Question

我有一个纯文本的自定义设置文件，读取该文件，然后每行代表变量设置。以下是文件包含的内容

在线 19X.13X.XX.1XX 地点规范关口存储路径

我可以加密文件并将其放在用户计算机上，我不希望他们对此进行任何更改或阅读文件上的内容

我可以将文件解密回光盘，但我不想这样，我需要的是仅在内存中使用这些值。

这是我必须回写解密文件（我在网上找到的东西）

    Public Function Decrypt(ByVal B() As Byte, ByVal PSW As String) As Byte()

    ' generates a key from the password
    Dim pdb As System.Security.Cryptography.PasswordDeriveBytes = New System.Security.Cryptography.PasswordDeriveBytes(PSW, New Byte() {1, 2, 3, 4, 5, 6, 7, 8, 9, 10})

    ' this holds the encrypted 
    Dim ms As System.IO.MemoryStream = New System.IO.MemoryStream()

    ' this object holds the information about the AES encryption
    Dim AESE As System.Security.Cryptography.Aes = New System.Security.Cryptography.AesManaged()
    AESE.Key = pdb.GetBytes(AESE.KeySize / 8)
    AESE.IV = pdb.GetBytes(AESE.BlockSize / 8)

    ' decrypt the data
    Dim cs As System.Security.Cryptography.CryptoStream = New System.Security.Cryptography.CryptoStream(ms, AESE.CreateDecryptor(), System.Security.Cryptography.CryptoStreamMode.Write)
    cs.Write(B, 0, B.Length)
    cs.Close()
    Return ms.ToArray()
End Function

我需要帮助来阅读每一行并将其分配给变量。提前谢谢
