c# - How to make foreach loop with custom class and List<> in class -

-

if have class:

    public class cacheclass     {         public string userid { get; set; }         public list<string> tabid { get; set; }         public list<string> state { get; set; }         public list<string> canadmin { get; set; }     }

then add value class , add cache. assign var type variable cache value:

    var k = system.web.httpcontext.current.cache[objuserinfo.userid.tostring()];

so, how can foreach loop var k , value?

as see k object (hover on var), since cache dictionary isn't typed. compiler doesn't know actual type cacheclass. step 1 cast it. prefer use as since won't throw exception if casting fails:

var k = system.web.httpcontext.current.cache[objuserinfo.userid.tostring()] cacheclass;

using as require to null-check make sure cast went okay:

if (k != null) {     foreach (string x in k.state)     {  } }

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
