c# - Avoid returning type Task<Object> from an async function when using HttpClient -


i making http calls using system.net.http.httpclient. seems calls must asynchronous.

let's have project structure of following: mvc web app -> business layer -> data layer

in data layer making http calls web api return data , end using function this:

public async task<ilist<product>> getproducts() {      httpresponsemessage response = await client.getasync("api/products");      string data = await response.content.readasstringasync();      ilist<product> products = jsonconvert.deserializeobject<ilist<product>>(data);       return products; }

this goes through businesslayer:

public task<ilist<product>> getproducts(string name = null) {      return _repository.getproducts(name); }

then in mvc controller:

public iactionresult index() {     task<ilist<product>> productstask = _manager.getproducts();      ilist<product> productsnontask = products.result.tolist();      return view(); }

do have make every single function return list of type task<ilist<product>> leading mvc controller? can see in mvc controller have retrieve products task wrapped around them. debugger looks kind of strange when go view list of products through it. can see convert them regular list of product.

i wondering if correct thing have of functions return type task<ilist<product>> way mvc controller or if there workaround functions can still return standard list of product continue use async capabilities of httpclient?

update: there wrong doing following:

public ilist<product> getproducts() {      task<httpresponsemessage> response = client.getasync("api/products");      if (response.result.issuccessstatuscode)      {           string data = response.result.content.readasstringasync().result;           ilist<product> products = jsonconvert.deserializeobject<ilist<product>>(data);            retval = products;      } }

if want operation asynchronous needs asynchronous way up.

the minute block on task wait or result it's no longer asynchronous.

so, no. either use async way or don't use @ all.

i wonder... if there workaround functions can still return standard list of product continue use async capabilities of httpclient?

no, there isn't really.

you should make code asynchronous comes many benefits in scalability , performance. if you're against doing can use webclient has synchronous web operations.

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
