c# - LINQ? Refactoring foreach -

-

is there better way write this? feel i'm getting rusty c# after doing lot of javascript lately. can improved?

    foreach (var item in this.cartitems)     {         if (item.effectiveprice != null)         {             this.cartitems[this.cartitems.indexof(item)].effectiveprice =                  currencyhelper.getlocalizedcurrency(item.effectiveprice);         }     }

well, could write in linq query syntax from , where, i'm not sure big change; i'd more interested in knowing if lookup unnecessary:

this.cartitems[this.cartitems.indexof(item)].effectiveprice =              currencyhelper.getlocalizedcurrency(item.effectiveprice);

to:

item.effectiveprice = currencyhelper.getlocalizedcurrency(item.effectiveprice);

other that, i'm not sure worth bother of changing it; i'd leave as:

foreach (var item in this.cartitems) {     if (item.effectiveprice != null) {         item.effectiveprice = currencyhelper.getlocalizedcurrency(item.effectiveprice);     } }

i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() .

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
