I finally solved it myself. The code posted for creating generic
methods did not work for me. Here is what does work for me:
(this is for my special case, the non generic arguments have to be add
to this method if needed)
public static MethodReference MakeGeneric(this MethodReference
aMethod, params TypeReference[] arguments)
{
//WARNING, aMethod plus aMethod.DeclaringType type must
have been imported before!
var _GenericType =
aMethod.DeclaringType.MakeGenericType(arguments);
var _GenericTypeReference =
aMethod.DeclaringType.Module.Import(_GenericType);
GenericParameter _GenericParameter = new
GenericParameter(_GenericType);
_GenericTypeReference.GenericParameters.Add(_GenericParameter);
MethodReference _MethodReference = new
MethodReference(aMethod.Name, aMethod.ReturnType)
{
DeclaringType = _GenericTypeReference,
HasThis = aMethod.HasThis,
ExplicitThis = aMethod.ExplicitThis,
CallingConvention = aMethod.CallingConvention,
};
foreach (GenericParameter _GenericParameter2 in
_GenericTypeReference.GenericParameters)
{
ParameterDefinition _ParameterDefintion = new
ParameterDefinition(_GenericParameter2);
_MethodReference.Parameters.Add(_ParameterDefintion);
}
_MethodReference =
aMethod.DeclaringType.Module.Import(_MethodReference);
return _MethodReference;
}
