c# - LINQ query on child list -


i'd write linq query checks object against list of objects inside object.

here i've come with, doesn't yield correct results, because defaults first one, objects @ both site 1 , site 2 show @ site 1:

filtereddata = data                .where(f => filterinfo.site.name.contains                                (f.etasites.firstordefault().site.name)).tolist()

so, data list, , within each data object, there list of etasites. each etasite has site. data object in more 1 site, i.e., there 2 etasites objects in list. query should pull data object has selected site in list. so, ones @ more 1 site, should able select site 1 or site 2 , return same data object.

try this:

filtereddata = data     .where(f => f.etasites         .any(a => filterinfo.site.name.contains(a.site.name)))     .tolist();

anyway, example above lets select exact matches in filter. believe should consider 1 below, if want use partial matching value in filterinfo.site.name:

filtereddata = data     .where(f => f.etasites         .any(a => a.site.name.contains(filterinfo.site.name)))     .tolist();

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
