c# - Set assembly level attribute conditionally -



c# - Set assembly level attribute conditionally -

i set assembly level attribute conditionally based on value read config file. possible?

i read attributes static metadata , while info can changed @ run-time, changes have no applicability after application has started.

what other alternatives have?

update

my objective: trying do

i using traceattribute trace method entry , exit points. switch on or off attribute @ assembly level based on value config file. i'd have off times turn on in emergency situations collect evidence of problem environment.

i think more answered here: can attributes added dynamically in c#?

i'm still not sure why need bind assembly level attribute , config key, can pass config key attribute's constructor/property , resolve value within attribute logic. like:

[attributeusage(attributetargets.assembly)] public class traceattribute : attribute { public traceattribute(string traceconfigkey) { var keyvalue = configurationmanager.appsettings[traceconfigkey]; dotracing = !string.isnullorempty(keyvalue) && bool.parse(keyvalue); } /// <summary> /// utilize property tracing conditional logic. /// </summary> public bool dotracing { get; private set; } }

then in assemblyinfo:

[assembly: trace("dotracing")]

and config file:

<appsettings> <add key="dotracing" value="true"/> </appsettings>

as solution, if utilize existing attribute, , cannot customize it, can add together conditional compilation symbol project properties, write:

#if trace [assembly: trace()] #endif

but needs project recompilation, of course.

c# .net attributes assemblies

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
