Question

我正在尝试评估程序的执行时间，但是却得到了错误的答案。完成> 20s的操作将注册为3s

这是我的代码：

   Public Function Encrypt(ByVal strValue As String) As String
    'Create instance of a Rijndael Managed object
    Dim aes As New RijndaelManaged
    'Set appropriate values of object
    aes.Padding = PaddingMode.PKCS7
    aes.KeySize = 256
    aes.Mode = CipherMode.CBC

    'Create streams to work with encryption process
    Dim msEncrypt As New MemoryStream()
    'SharedKey = "64 byte string"
    'IV = "32 byte string"
    Dim SharedKey As Byte() = Encoding.GetEncoding(1252).GetBytes(strSharedKey)
    Dim IV As Byte() = Encoding.GetEncoding(1252).GetBytes(strIV)
    Dim csEncrypt As New CryptoStream(msEncrypt, aes.CreateEncryptor(SharedKey, IV), CryptoStreamMode.Write)
    'Convert string value to byte array
    Dim toEncrypt As Byte() = Encoding.GetEncoding(1252).GetBytes(strValue)
    toEncrypt = Encoding.Convert(Encoding.GetEncoding(1252), Encoding.UTF8, toEncrypt)
    'Perform encryption

    csEncrypt.Write(toEncrypt, 0, toEncrypt.Length)
    csEncrypt.FlushFinalBlock()
    'Return Base64 string
    Return Convert.ToBase64String(msEncrypt.ToArray())

    'Dim u As System.Text.UnicodeEncoding = System.Text.Encoding.Unicode
    'Dim a As System.Text.ASCIIEncoding = System.Text.Encoding.ASCII
    'Return a.GetByteCount(SharedKey)  '64 bytes

End Function

我在start_time的初始声明周围加上了星号。抱歉，所有代码都转储了，但是我真的不知道time（）有什么问题。

Python time.time（）提供不正确的结果
