Hi all.
I have an assembly and I need to convert it to byte[] or Stream.
I used following code:

byte[] bytes;  
 
MemoryStream stream = new MemoryStream();  
BinaryFormatter formatter = new BinaryFormatter();  
formatter.AssemblyFormat = 
    System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Full;
formatter.Serialize(stream, results.CompiledAssembly);  
bytes = stream.ToArray();

However, the load fails with the following error message.

{"Bad IL format."} "Could not load file or assembly '169 bytes loaded from Orion.ExpressionEngine, Version=3.5.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format."

Sorry for my english

Solution 1

It would help to know what line gives the error. Why do you need to do this at runtime ? Aren't you really trying to turn your exe into a byte array ? Why not read it from the HDD ?

>>> Why do you need to do this at runtime ? Aren't you really trying to turn your exe into a byte array ? Why not read it from the HDD ?

There are many reasons why he would want to do it this way:
1/ loading an assembly in a separate AppDomain using the byte[] version of the Assembly if load from file has failed (typically when code is obfuscated, Types don't show up and GetTypes fails, as well as Load. You have to go module by module and use try.. catch to select only those modules you can load.
