asp.net - C# using Linq in Querable -


i'm bit new linq , hoping me on i'm strugling.

i have 2 list

public iqueryable<trole> roles {       {       var roles = new list<trole>();       roles.add(createidentityrole("chairman", "voorzitter"));       roles.add(createidentityrole("treasurer", "penningmeester"));       roles.add(createidentityrole("ranking responsible", "rankingverantwoordelijke"));                 roles.add(createidentityrole("competition responsible", "competitieverantwoordelijke"));       roles.add(createidentityrole("webmaster", "webbeheerder"));       roles.add(createidentityrole("secretary", "secretaris"));       foreach(trole role in roles)       {          if (!_roles.contains(role))             _roles.add(role);       }        return _roles.asqueryable<trole>();    } }  private trole createidentityrole(string id, string name) {    trole role = (trole)activator.createinstance(typeof(trole));    role.id = id;    role.name = name;    return role; }  public void initializeprivacy(identityuser user) {    var manager = context.getowincontext().getusermanager<applicationusermanager>();    var rolemanager = new rolestore<identityrole>();    var roles = rolemanager.roles;    list<string> userroles = manager.getroles(user.id); }

right want use linq roles not found in userroles. because roles querable not how achieve such result.

you can use ienumerable interface. if method return querable result work. try this:

ienumerable<string> roles = rolemanager.roles; list<string> userroles = getroles(user.id);  var result = roles.except(userroles);

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...
