aes c# java_下面Java的AES加密，用c#怎么实现？要一样的结果哦

实现AES加密的关键在于加密算法和加密模式需要一致。下面是Java实现AES加密的代码：

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

public class AESUtil {

    public static byte[] encrypt(byte[] key, byte[] initVector, byte[] data) throws Exception {
        SecretKeySpec keySpec = new SecretKeySpec(key, "AES");
        IvParameterSpec iv = new IvParameterSpec(initVector);
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5PADDING");
        cipher.init(Cipher.ENCRYPT_MODE, keySpec, iv);
        return cipher.doFinal(data);
    }
}

下面是C#实现AES加密的代码：

using System;
using System.Security.Cryptography;

public class AESUtil
{
    public static byte[] Encrypt(byte[] key, byte[] initVector, byte[] data)
    {
        using (Aes aesAlg = Aes.Create())
        {
            aesAlg.Key = key;
            aesAlg.IV = initVector;
            aesAlg.Mode = CipherMode.CBC;
            aesAlg.Padding = PaddingMode.PKCS7;

            ICryptoTransform encryptor = aesAlg.CreateEncryptor(aesAlg.Key, aesAlg.IV);

            byte[] encryptedData;
            using (var msEncrypt = new System.IO.MemoryStream())
            {
                using (var csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
                {
                    csEncrypt.Write(data, 0, data.Length);
                    csEncrypt.FlushFinalBlock();
                }
                encryptedData = msEncrypt.ToArray();
            }

            return encryptedData;
        }
    }
}

注意，这里使用了`Aes`类进行AES加密，而且加密模式和填充模式需要和Java代码保持一致（`CipherMode.CBC`和`PaddingMode.PKCS7`）。同时，需要注意的是，Java和C#中默认的编码方式不同，可能会影响加密结果，所以在实际使用中需要注意编码方式的一致性。
