VS创建一个项目A，生成一个序列化的加密文件**.lic，然后，创建项目B，反序列化读出A项目生成的加密文件**.lic并解密，这时候，提示错误：无法找到程序集，是A项目中的。
代码：A项目：
#region DES加密

{
try
{
int number = 0;
SymmetricAlgorithm sa = DES.Create();
try
{
sa.Key = InitKey(EncryptKey);
}
catch { return "密钥生成失败！"; }
sa.IV = new byte[] { 148, 255, 64, 249, 29, 140, 50, 48 };
sa.Mode = CipherMode.CBC;
sa.Padding = PaddingMode.Zeros;
BinaryFormatter bf = new BinaryFormatter();
byte[] plainBytes;
Message msg = new Message();
msg.Num = number;
msg.MessageBody = EncryptString;
using (MemoryStream stream = new MemoryStream())
{
bf.Serialize(stream, msg);
plainBytes = stream.ToArray();
}
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, sa.CreateEncryptor(), CryptoStreamMode.Write);
cs.Write(plainBytes, 0, plainBytes.Length);
cs.Close();
byte[] cipherBytes = ms.ToArray();
StringBuilder sb = new StringBuilder();
for (Int32 i = 0; i < cipherBytes.Length; i++)
{
if (i == cipherBytes.Length - 1)
sb.Append(string.Format("{0:X2}", cipherBytes[i]));
else
sb.Append(string.Format("{0:X2}-", cipherBytes[i]));
}
ms.Close();
return sb.ToString();
}
catch (Exception ex) { return "加密失败，失败原因：" + ex.Message; }

两个项目的类名一样，但他们是不同的类，通常情况下是这样的
项目A的类是ProjectA.Message
项目B的类是ProjectB.Message
你使用ProjectA的Message类序列化在字符串后，先别加密，你看看里面产生的字符串就知道了。
如果要处理你这种情况，通常一个简单的方法是创建一人项目C，里面放置Message类。
项目A引用项目C，项目B也引用项目C，序列化与反序列化都是同一个类，这样就没有问题了。

这个和加解密没什么关系吧。你看看是不是别的地方的问题？

缺少引用吧？是不是哪个程序集没有引用啊
