Question

I receive byte array what contains assembly data.
How i can get assembly name from this data without loading assembly in appdomain ?

var assemblyName = GetAssemblyName(byte[] asmData);//doesn't load assembly to appDomain.

Answer 1

To get the assembly name without loading it into the current app domain, create a new AppDomain, use AppDomain.Load then call the FullName property. For example:

byte[] asmData;  // Contains the assembly data

AppDomain appDomain = AppDomain.CreateDomain("MyDomain");
Assembly assembly = appDomain.Load(asmData);
string name = assembly.FullName;
AppDomain.Unload(appDomain);

According to MSDN, assuming no other domains have loaded that assembly, it should be unloaded without being loaded into the current app domain.

If you do not want to load it into any app domain, save the bytes to a file and use AssemblyName.GetAssemblyName method.
