blocks|key|285540|text|System.Reflection.Assembly实现了ISerializable。创建一个BinaryFormatter实例，并在任何流上调用它的Serialize方法--+MemoryStream、FileStream等。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|285541|Assembly+yourAssembly;
var+formatter+=+new+BinaryFormatter();
var+ms+=+new+MemoryStream();

System.Reflection.Assembly implements ISerializable. Create an instance of BinaryFormatter and call its Serialize method on any stream - MemoryStream, FileStream, etc.

<pre><code>Assembly yourAssembly;
var formatter = new BinaryFormatter();
var ms = new MemoryStream();
formatter.Serialize(ms, yourAssembly);
var reloadedAssembly = Assembly.Load(ms.GetBuffer()); 
</code></pre>

blocks|key|563323|text|无论程序集的位置如何，System.Security.Policy.Hash都能够计算哈希。因此，我们至少有两种方法可以将程序集获取为字节数组：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|563324|1)使用反射：|563325|var+hash+=+new+Hash(assembly);
var+dllAsArray+=+(byte[])+hash.GetType()
++++.GetMethod("GetRawData",+BindingFlags.Instance+%7C+BindingFlags.NonPublic)
++++.Invoke(hash,+new+object[0]);|code-block|syntax|javascript|563326|2)使用伪HashAlgorithm实现：|563327|public+class+GetWholeBodyPseudoHash+:+HashAlgorithm
{
++++protected+override+void+Dispose(bool+disposing)
++++{
++++++++if(disposing)+_memoryStream.Dispose();
++++++++base.Dispose(disposing);

++++static+GetWholeBodyPseudoHash()
++++{

++++protected+override+byte[]+HashFinal()
++++{

}

...
var+bytes+=+new+Hash(yourAssembly).GenerateHash(new+GetWholeBodyPseudoHash());|563328|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|Q|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

System.Security.Policy.Hash is able to calculate a Hash regardless of the assembly's location. So we have at least 2 ways to obtain an assembly as a byte array:

1) Using reflection:

<pre><code>var hash = new Hash(assembly);
var dllAsArray = (byte[]) hash.GetType()
 .GetMethod("GetRawData", BindingFlags.Instance | BindingFlags.NonPublic)
 .Invoke(hash, new object[0]);
</code></pre>

2) Using a fake HashAlgorithm implementation:

<pre><code>public class GetWholeBodyPseudoHash : HashAlgorithm
{
 protected override void Dispose(bool disposing)
 {
 if(disposing) _memoryStream.Dispose();
 base.Dispose(disposing);
 }

 static GetWholeBodyPseudoHash()
 {
 CryptoConfig.AddAlgorithm(typeof(GetWholeBodyPseudoHash), typeof(GetWholeBodyPseudoHash).FullName);
 }

 private MemoryStream _memoryStream=new MemoryStream();
 public override void Initialize()
 {
 _memoryStream.Dispose();
 _memoryStream = new MemoryStream();
 }

 protected override void HashCore(byte[] array, int ibStart, int cbSize)
 {
 _memoryStream.Write(array, ibStart, cbSize);
 }

 protected override byte[] HashFinal()
 {
 return _memoryStream.ToArray();
 }
}

...
var bytes = new Hash(yourAssembly).GenerateHash(new GetWholeBodyPseudoHash());
</code></pre>

blocks|key|285563|text|要将程序集从AppDomain转换为byte[]，请使用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|285564|var+pi+=+assembly.GetType().GetMethod("GetRawBytes",+BindingFlags.Instance+%7C+BindingFlags.NonPublic);
byte[]+assemblyBytes+=+(byte[])+pi.Invoke(assembly,+null);|code-block|syntax|javascript|285565|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

To convert an assembly from AppDomain to byte[] use:

<pre><code>var pi = assembly.GetType().GetMethod("GetRawBytes", BindingFlags.Instance | BindingFlags.NonPublic);
byte[] assemblyBytes = (byte[]) pi.Invoke(assembly, null);
</code></pre>

I notice that there is a method of <code>System.Reflection.Assembly</code>, which is <code>Assembly Load(byte[] rawAssembly)</code>.

I wonder if there is an opposite operation like <code>byte[] Store(Assembly assembly)</code>. If not, how can I convert an assembly object to <code>byte[]</code> for calling <code>Assembly Load(byte[] rawAssembly)</code> totally in memory without writing the assembly to a file? Thanks!

Comment: The question comes from the situation that I am using a third-party library which returns an Assembly instance to me, and I must use reflection to call its methods. I don't know how the library creates this assembly object. I just wonder if I can store the assembly object to byte[] and reload it with 'Assembly Load(byte[] rawAssembly)'. Thanks!

Opposite operation to Assembly Load(byte[] rawAssembly)
