求大侠将此段JAVA翻译为C#

求哪位大侠将此段JAVA翻译为C#，代码如下：

public class DigestUtil {
	private static String encodingCharset = "UTF-8";
	public static String hmacSign(String aValue, String aKey) {
		byte k_ipad[] = new byte[64];
		byte k_opad[] = new byte[64];
		byte keyb[];
		byte value[];
		try {
			keyb = aKey.getBytes(encodingCharset);
			value = aValue.getBytes(encodingCharset);
		} catch (UnsupportedEncodingException e) {
			keyb = aKey.getBytes();
			value = aValue.getBytes();
		}

		Arrays.fill(k_ipad, keyb.length, 64, (byte) 54);
		Arrays.fill(k_opad, keyb.length, 64, (byte) 92);
		for (int i = 0; i < keyb.length; i++) {
			k_ipad[i] = (byte) (keyb[i] ^ 0x36);
			k_opad[i] = (byte) (keyb[i] ^ 0x5c);
		}

		MessageDigest md = null;
		try {
			md = MessageDigest.getInstance("MD5");
		} catch (NoSuchAlgorithmException e) {

			return null;
		}
		md.update(k_ipad);
		md.update(value);
		byte dg[] = md.digest();
		md.reset();
		md.update(k_opad);
		md.update(dg, 0, 16);
		dg = md.digest();
		return toHex(dg);
	}

	public static String toHex(byte input[]) {
		if (input == null)
			return null;
		StringBuffer output = new StringBuffer(input.length * 2);
		for (int i = 0; i < input.length; i++) {
			int current = input[i] & 0xff;
			if (current < 16)
				output.append("0");
			output.append(Integer.toString(current, 16));
		}

		return output.toString();
	}

	public static String getHmac(String[] args, String key) {
		if (args == null || args.length == 0) {
			return (null);
		}
		StringBuffer str = new StringBuffer();
		for (int i = 0; i < args.length; i++) {
			str.append(args[i]);
		}
		return (hmacSign(str.toString(), key));
	}

	public static String digest(String aValue) {
		aValue = aValue.trim();
		byte value[];
		try {
			value = aValue.getBytes(encodingCharset);
		} catch (UnsupportedEncodingException e) {
			value = aValue.getBytes();
		}
		MessageDigest md = null;
		try {
			md = MessageDigest.getInstance("SHA");
		} catch (NoSuchAlgorithmException e) {
			e.printStackTrace();
			return null;
		}
		return toHex(md.digest(value));
	}
	
	public static String removeHmacContext(String xml) {
		return xml.replaceAll("<Hmac>.+</Hmac>", "<Hmac></Hmac>");
	}

	
	public static String addHmacContext(String xml,String aKey) {
		return xml.replaceAll("<Hmac></Hmac>", "<Hmac>" + hmacSign(xml,aKey) + "</Hmac>");
	}
	
	public static String getHmacFromContext(String xml){
		int s =  xml.indexOf("<Hmac>")+6;
		int i =  xml.indexOf("</Hmac>");
		return xml.substring(s, i);
		
	}
	public static void main(String[] args) {
		String s = "123456";
		String res = hmacSign(s, "E83Jjif8e83jJt");
		System.out.println("res:"+res);
	}
}

[娃都会打酱油了]

HMACMD5 md5 = new HMACMD5(Encoding.UTF8.GetBytes("E83Jjif8e83jJt"));
var tmp = md5.ComputeHash(Encoding.UTF8.GetBytes("123456"));
Console.WriteLine(BitConverter.ToString(tmp).Replace("-", string.Empty).ToLower());
//输出：8ead2d78450a46b9d86cf2c705d78748

结果一致吗？

public static String hmacSign(String aValue, String aKey) 这个结果一致。 大侠，还有这个呢，麻烦一并翻译成c#吧，感谢！ public static String digest(String aValue) { aValue = aValue.trim(); byte value[]; try { value = aValue.getBytes(encodingCharset); } catch (UnsupportedEncodingException e) { value = aValue.getBytes(); } MessageDigest md = null; try { md = MessageDigest.getInstance("SHA"); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); return null; } return toHex(md.digest(value)); }

这个就是简单的sha1摘要，你网上随便找下就行了
