c# - Is the result of MethodBody.GetILAsByteArray Method being cached? If so, how to clear the cache? -


as android game developer, using methodbody.getilasbytearray method il codes detect if given method has been modified (injected) user using other app (e.g. cheat engine). example,

class {     public foo()     {         // here.     }      public static byte[] getilbytecode() {         return typeof(a).getmethodinfo("foo").getmethodbody().getilasbytearray();     } }

i can injected version of function "foo" if call function a.getilbytecode() after function "foo" being injected.

if call a.getilbytecode() first, , inject code in "foo". when call a.getilbytecode() again, return origin version of function "foo" instead of injected version.

it seems result of getilasbytearray() cached.

so question is, can clear cache of getilasbytearray(), , updated il code of target method?

since reflection expensive. .net runtime caches types pulled reflection, , in each 1 of these caches members called reflection.

i believe can try exhausting type cache, has few members (i think 16 members). member cache might unlimited.

however, if using cheatengine, don't think changing il changing actual jitted code. don't think there can here.

clr jit compiles every method gets called, don't know if mono offers interpretation mode.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
