属性设置在加密解密时不一致出现“填充无效，无法被移除”的错误。但是这只是其中的一个原因。
rDel.Key = resultArray;
rDel.BlockSize = 128;
rDel.Mode = CipherMode.ECB;
rDel.Padding = PaddingMode.Zeros;
加解密属性名一致还是报错
交初始key的位置互换正常。具体是初始化属性有先后顺序
代码如下：
public static string AesEncrypt(string str, string key)
{
if (string.IsNullOrEmpty(str)) return null;
Byte[] toEncryptArray = Encoding.UTF8.GetBytes(str);
System.Security.Cryptography.RijndaelManaged rm = new
System.Security.Cryptography.RijndaelManaged
{
BlockSize =128,
KeySize=256,
Key = Encoding.UTF8.GetBytes(key),
Mode = System.Security.Cryptography.CipherMode.ECB,
Padding = System.Security.Cryptography.PaddingMode.PKCS7,
};
System.Security.Cryptography.ICryptoTransform cTransform = rm.CreateEncryptor();
Byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
return Convert.ToBase64String(resultArray, 0, resultArray.Length);
}
public static string AesDecrypt(string str, string key)
{
if (string.IsNullOrEmpty(str)) return null;
Byte[] toEncryptArray = Convert.FromBase64String(str);
System.Security.Cryptography.RijndaelManaged rm = new
System.Security.Cryptography.RijndaelManaged
{
BlockSize = 128,
KeySize = 256,
Key = Encoding.UTF8.GetBytes(key),
Mode = System.Security.Cryptography.CipherMode.ECB,
Padding = System.Security.Cryptography.PaddingMode.PKCS7
};
System.Security.Cryptography.ICryptoTransform cTransform = rm.CreateDecryptor();
Byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
return Encoding.UTF8.GetString(resultArray);
}
