一段java的代码改写成c#代码？

Question

现在有如下一段java代码
String content="xxxff";
String str=DigestUtils.md5Hex(content.getBytes("utf-8"));改写成c#代码。

Answer 1

String content = "xxxff";
            MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
            String str = System.Text.Encoding.Default.GetString(md5.ComputeHash(System.Text.Encoding.UTF8.GetBytes(content)));

Answer 2

楼上这是加密的java方法吧
以下是C#中加密的方法。 直接将要加密的字符串传进入就可以了。
public static string Encrypt(string text)
        {
            Rijndael crypt = Rijndael.Create();
            byte[] key = new byte[32]{0XA6,0X7D,0XE1,0X3F,0X35,0X0E,0XE1,0XA9,0X83,0XA5,0X62,0XAA,0X7A,0XAE,0X79,0X98,
            0XA7,0X33,0X49,0XFF,0XE6,0XAE,0XBF,0X8D,0X8D,0X20,0X8A,0X49,0X31,0X3A,0X12,0X40};
            byte[] iv = new byte[16] { 0XF8, 0X8B, 0X01, 0XFB, 0X08, 0X85, 0X9A, 0XA4, 0XBE, 0X45, 0X28, 0X56, 0X03, 0X42, 0XF6, 0X19 };            crypt.Key = key;
            crypt.IV = iv;
            MemoryStream ms = new MemoryStream();
            ICryptoTransform transformEncode = new ToBase64Transform();
            //Base64编码
            CryptoStream csEncode = new CryptoStream(ms, transformEncode, CryptoStreamMode.Write);            CryptoStream csEncrypt = new CryptoStream(csEncode, crypt.CreateEncryptor(), CryptoStreamMode.Write);            System.Text.UTF8Encoding enc = new System.Text.UTF8Encoding();
            byte[] rawData = enc.GetBytes(text);            csEncrypt.Write(rawData, 0, rawData.Length);
            csEncrypt.FlushFinalBlock();            byte[] encryptedData = new byte[ms.Length];
            ms.Position = 0;
            ms.Read(encryptedData, 0, (int)ms.Length);
            return enc.GetString(encryptedData);
        }

以下是解密的方法。希望对你有用
public static string Decrypt(string text)
        {
            Rijndael crypt = Rijndael.Create();
            byte[] key = new byte[32]{0XA6,0X7D,0XE1,0X3F,0X35,0X0E,0XE1,0XA9,0X83,0XA5,0X62,0XAA,0X7A,0XAE,0X79,0X98,
            0XA7,0X33,0X49,0XFF,0XE6,0XAE,0XBF,0X8D,0X8D,0X20,0X8A,0X49,0X31,0X3A,0X12,0X40};
            byte[] iv = new byte[16] { 0XF8, 0X8B, 0X01, 0XFB, 0X08, 0X85, 0X9A, 0XA4, 0XBE, 0X45, 0X28, 0X56, 0X03, 0X42, 0XF6, 0X19 };            crypt.Key = key;
            crypt.IV = iv;            MemoryStream ms = new MemoryStream();            CryptoStream csDecrypt = new CryptoStream(ms, crypt.CreateDecryptor(), CryptoStreamMode.Write);            ICryptoTransform transformDecode = new FromBase64Transform();
            CryptoStream csDecode = new CryptoStream(csDecrypt, transformDecode, CryptoStreamMode.Write);            System.Text.UTF8Encoding enc = new System.Text.UTF8Encoding();
            byte[] rawData = enc.GetBytes(text);
            csDecode.Write(rawData, 0, rawData.Length);
            csDecode.FlushFinalBlock();            byte[] decryptedData = new byte[ms.Length];
            ms.Position = 0;
            ms.Read(decryptedData, 0, (int)ms.Length);
            return (enc.GetString(decryptedData));
        }
