i'm trying define generic class accept argument value type (actually enum) , initialize const field it's default type. i want like: public abstract class genericclass<valuetype> valuetype: struct, iconvertible { public const valuetype val = default(valuetype); } unfortunately compiler complaints (i'm using mono think it's same on .net). error following: error cs1959: type parameter `valuetype' cannot declared const what's error? type parameter not allowed constant type. because struct cannot made const (from c# specification 10.4 constants ) the type specified in constant declaration must sbyte , byte , short , ushort , int , uint , long , ulong , char , float , double , decimal , bool , string , enum-type, or reference-type. a kind of workaround limitation declare static readonly . public static readonly valuetype val = default(valuetype);

i trying find alternative following can take advantage of is operator. public bool isoftype(type type) { return this._item.gettype() == type; } something similar following, not compile. public bool isoftype(type type) { return this._item type; } i think you're looking type.isassignablefrom : public bool isoftype(type type) { return _item != null && type.isassignablefrom(_item.gettype()); } or if can make method generic, that's simpler can use is type parameter: public bool isoftype<t>() { return _item t; } edit: noted in wim's answer, there's type.isinstanceof makes non-generic method simpler: public bool isoftype(type type) { return type.instanceof(_item); }

if class a in unique_ptr<a> it's own destructor, necessary declare deleter ensure unique pointer uses destructor? example thinking of a has member mx of type user_matrix (a name made up) needs call function free(...) release memory, 1 define ~a(){ user_matrix::free(mx); /*etc*/} since default_deleter<> call delete , understanding that should use ~a() . however, example opening , closing of directories in section 5.2, under "deleters associated resources", of book of josuttis (the c++ standard library: tutorial , reference) suggests 1 may need declare special deleter this, confused.... because, in given example, class dir doesn't have destructor uses closedir(...) ? the default deleter of std::unique_ptr<t> call delete , default deleter of std::unique_ptr<t[]> call delete[] , call destructors of objects appropriately. what may happen operation need scheduled right before destruction, either because destructor incom...
