DES加密解密报错【不正确的数据】急急急求大神帮助

[碎碎0_o]

加密解密，有些能加密解密出来，有些报错说【不正确的数据。】，还有些加密解密出来是错的
例：textBox1中文本为【BLue@210896】时，就是不正确的数据，文本改成【BLue@210896 】（后面随便加空格什么的），就正常了。
private void button1_Click(object sender, EventArgs e)
{
this.textBox2.Text = EncryptorStr1(this.textBox1.Text, enckey, encIV);
this.textBox3.Text = DecryptorStr1(this.textBox2.Text, enckey, encIV);

}
Byte[] enckey = { 0x01, 0x11, 0x11, 0x11, 0x01, 0x01, 0x01, 0x01 };
Byte[] encIV = { 0x02, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01 };
#region 加密
//加密后返回十六进制字符串
private string EncryptorStr1(string encyptstr, byte[] key, byte[] IV)
{
byte[] enbyte = Encoding.Unicode.GetBytes(encyptstr);//ConvertStringToByteArray(encyptstr);
MemoryStream fs = new MemoryStream(enbyte, 0, enbyte.Length);
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
ICryptoTransform desencrypt = des.CreateEncryptor(key, IV);
CryptoStream cryptostream = new CryptoStream(fs, desencrypt, CryptoStreamMode.Read);
string str = (new StreamReader(cryptostream, new UnicodeEncoding())).ReadToEnd();
fs.Close();
cryptostream.Close();
//转换为十六进制
byte[] aa = Encoding.Unicode.GetBytes(str);
str = "";
for (int i = 0; i < aa.Length; i++)
{
if (aa[i].ToString("X").Length == 1)
str += "0";
str += aa[i].ToString("X");
}
return str;

}

代码那么长，懒得看，你看一下是不是你数据没有取全

大神，解密在byte[] enbyte = ConvertStringToByteArray(decryptstr);这里的时候，这个enbyte还是对的呀，而且加密的内容换一下又可以

代码不全，无法测试！

form里就三个TextBox和一个Button，Button点击事件绑定到button1_Click，代码就没了呀

[xuzuning]

ConvertStringToByteArray 呢？

啊啊啊，我都是复制一份出来改坏了又复制一份，然后有点乱，漏掉了这个，不好意思不好意思 private static Byte[] ConvertStringToByteArray(String s) { return (new UnicodeEncoding()).GetBytes(s); }

有人吗有大神在吗

没人答了，结贴散分
