how can string constant automatically set datestamp @ compile time? something like: const string compile_datestamp = eval_static(datetime.now().tostring()); ... string s = "this program compiled $compile_datestamp"; where s e.g. "this program compiled 1971-02-03 04:05:06" thanks question! there's no required compile step in dart. (we have optional dart-to-javascript compiler, or dart-to-dart processor tree shaking.) dart's vm accepts input text files. similar ruby or python, runs text-based scripts. as others have mentioned, job sort of build step.

i started learning c# week ago. have little experience objective c. give me hard time asking such beginner question. well, user able select combo box. created combobox visually in xaml. contents of combo box strings. however, when user selects string of choice, store value int can calculations. errors have been can't convert object string , many other conversation errors. int x; string selvalue = (string)combobox1.selectedvalue; if ((selvalue=="green")||(selvalue=="blue")) { x= 5; } would best create function accepts object , returns int, if please tell ? you should have string green selectedtext , value int 5 selectedvalue, way can drop code & int x = (int)combobox1.selectedvalue, give 5. need google winform combobox databinding, you'll see can bind diferent properties text & value.

i'm trying find everywhere in solution specific enum converted string, whether or not tostring() explicitly called. (these being replaced conversion using enum descriptions improve obfuscation.) example: i'd find code such string str = "value: " + someenum.somevalue; i've tried replacing enum wrapper class containing implicit conversions enum type , overriding tostring() in wrapper class, when try searching uses of tostring() override gives me list of places in solution tostring() called on (and called explicitly). search done resharper in visual studio. is there way find these enum-to-string conversions? going through entire solution manually doesn't sound fun. the trick in roslyn use semanticmodel.gettypeinfo() , check convertedtype find these sort of implicit conversions. a complete example: using system; using system.collections.generic; using system.linq; using system.text; using roslyn.compilers; using roslyn.compilers.csharp;...
