在C#中实现AES加密可以通过使用AesManaged类来实现。下面是一个简单的示例代码：

usingSystem;
usingSystem.IO;
usingSystem.Security.Cryptography;
usingSystem.Text;

publicclassAesEncryption
{
publicstaticstringEncrypt(stringplainText,stringkey,stringiv)
{
byte[]keyBytes=Encoding.UTF8.GetBytes(key);
byte[]ivBytes=Encoding.UTF8.GetBytes(iv);

byte[]encryptedBytes;

using(AesManagedaes=newAesManaged())
{
aes.Key=keyBytes;
aes.IV=ivBytes;

ICryptoTransformencryptor=aes.CreateEncryptor(aes.Key,aes.IV);

using(MemoryStreamms=newMemoryStream())
{
using(CryptoStreamcs=newCryptoStream(ms,encryptor,CryptoStreamMode.Write))
{
using(StreamWritersw=newStreamWriter(cs))
{
sw.Write(plainText);
}

encryptedBytes=ms.ToArray();
}
}
}

returnConvert.ToBase64String(encryptedBytes);
}

publicstaticstringDecrypt(stringencryptedText,stringkey,stringiv)
{
byte[]keyBytes=Encoding.UTF8.GetBytes(key);
byte[]ivBytes=Encoding.UTF8.GetBytes(iv);

byte[]encryptedBytes=Convert.FromBase64String(encryptedText);
stringdecryptedText;

using(AesManagedaes=newAesManaged())
{
aes.Key=keyBytes;
aes.IV=ivBytes;

ICryptoTransformdecryptor=aes.CreateDecryptor(aes.Key,aes.IV);

using(MemoryStreamms=newMemoryStream(encryptedBytes))
{
using(CryptoStreamcs=newCryptoStream(ms,decryptor,CryptoStreamMode.Read))
{
using(StreamReadersr=newStreamReader(cs))
{
decryptedText=sr.ReadToEnd();
}
}
}
}

returndecryptedText;
}
}
