c# - Retrieve Type Foo<Bar> from name when Bar is created from TypeBuilder -

i creating types using typebuilder. these types used arguments in generic class. want create type name. fact generic parameter dynamic seems barrier.

static public class dynamictypetest {     public class generic<t> { }      static public void test()     {         type dynamictype = createdynamictype();         type generictype = typeof(generic<>);          // generic<dynamictype>         type genericdynamictype = generictype.makegenerictype(new type[]{dynamictype});          debug.assert(typefromname(genericdynamictype.fullname) == genericdynamictype);              // fail         debug.assert(typefromname(genericdynamictype.assemblyqualifiedname) == genericdynamictype); // fail         debug.assert(typefromname(genericdynamictype.name) == genericdynamictype);                  // fail          // generic<int>         type genericinttype = generictype.makegenerictype(new type[] { typeof(int) });          debug.assert(typefromname(genericinttype.fullname) == genericinttype); // succeeds. replacing 'int' type defined in project works     }      // essence of want     static private type typefromname(string name)     {         return assembly.getexecutingassembly().gettype(name);     }      static private type createdynamictype()     {         assemblyname assemblyname = new assemblyname("dynamicassembly");         assemblybuilder assemblybuilder = appdomain.currentdomain.definedynamicassembly(assemblyname, assemblybuilderaccess.run);         modulebuilder modulebuilder = assemblybuilder.definedynamicmodule("dynamicmodule");         typeattributes typeattributes = typeattributes.public | typeattributes.class | typeattributes.autoclass | typeattributes.ansiclass;         typebuilder typebuilder = modulebuilder.definetype("dynamictype", typeattributes, typeof(system.object));          return typebuilder.createtype();     } } 

obviously know how create type makegenerictype, in real-life scenario working with, don't want (or can't) mangle type name can create types separately , piece them together.

how can recreate kind of type string name?

it occurred me should use version of assembly.gettype() throws exception on error. threw filenotfoundexception, apparently, in generic arguments, assemblies file allowed. around this, registered assemblyresolve event appdomain, , handled case dynamicassembly not found on file. working code:

static public class dynamictypetest {     public class generic<t> { }      static public void test()     {         appdomain.currentdomain.assemblyresolve += currentdomain_assemblyresolve;          type dynamictype = createdynamictype();         type generictype = typeof(generic<>);          // generic<dynamictype>         type genericdynamictype = generictype.makegenerictype(new type[]{dynamictype});          debug.assert(typefromname(genericdynamictype.fullname) == genericdynamictype); // pass          appdomain.currentdomain.assemblyresolve -= currentdomain_assemblyresolve;     }      static assembly currentdomain_assemblyresolve(object sender, resolveeventargs args)     {         foreach (assembly assembly in appdomain.currentdomain.getassemblies())         {             assemblyname assemblyname = assembly.getname();              if (args.name == assemblyname.fullname)             {                 return assembly;             }         }          return null;     }      // essence of want     static private type typefromname(string name)     {         try         {             return typeof(generic<>).assembly.gettype(name, true);         }         catch (exception)         {             return null;         }     }      static private type createdynamictype()     {         assemblyname assemblyname = new assemblyname("dynamicassembly");         assemblybuilder assemblybuilder = appdomain.currentdomain.definedynamicassembly(assemblyname, assemblybuilderaccess.run);         modulebuilder modulebuilder = assemblybuilder.definedynamicmodule("dynamicmodule");         typeattributes typeattributes = typeattributes.public | typeattributes.class | typeattributes.autoclass | typeattributes.ansiclass;         typebuilder typebuilder = modulebuilder.definetype("dynamictype", typeattributes, typeof(system.object));          return typebuilder.createtype();     }
