求助微信付款到银行卡，一直提示解密真实姓名或银行卡号出错

[jimmmmm]

publickey = @"<RSAKeyValue><Modulus>" + publickey.Replace("-----BEGIN RSA PUBLIC KEY-----", "").Replace("-----END RSA PUBLIC KEY-----", "").Replace("\n", "") + "</Modulus><Exponent>AQAB</Exponent></RSAKeyValue>";



RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();


rsa.FromXmlString(publickey);


byte[] cipherbytes = rsa.Encrypt(Encoding.Default.GetBytes(content), false);

return Convert.ToBase64String(cipherbytes);


公钥不管是PKCS#1还是PKCS#8都不行，实在是没辙了，求救求救求救！！！！

如能解决必重谢
