一个是RSA 公钥加密一个是Aes 加密
怎么写才是正确的

对应易语言里面的

KEY的ras加密＝编码_BASE64编码 (RSA.公钥_加密 (到字节集 (“abc”)))
KEY的ras加密＝子文本替换 (KEY的ras加密, “+”, “-”, , , 真)
KEY的ras加密＝子文本替换 (KEY的ras加密, “/”, “_”, , , 真)

加密后密文＝编码_BASE64编码 (对称加密 (文本到UTF8 (“abc”), 到字节集 (“4a2c09ffbc6e7d0414d1ae731e3a0ce5”), #对称算法_AES_256_CBC, #数据填充_PKCS7_PADDING, 取空白字节集 (16)))
加密后密文＝子文本替换 (加密后密文, “+”, “-”, , , 真)
加密后密文＝子文本替换 (加密后密文, “/”, “_”, , , 真)

    byte[] keyBytes = Encoding.UTF8.GetBytes(key); // 正好32字节
    byte[] ivBytes = new byte[16]; // 16字节全0
    
    using (Aes aes = Aes.Create())

        aes.Key = keyBytes;

保持RSA加密不变（你已经写对了），AES加密的key保持为32字节字符串（对应AES-256），IV使用16字节全0，其他的加密参数和替换逻辑都已经正确
