asp.net mvc - Error consuming rest API in .net -

i'm trying consume rest api i'm getting next error:

exception details: newtonsoft.json.jsonexception: unexpected json token while reading datatable: startobject

also, if changing endpoint get: system.outofmemoryexception: exception of type 'system.outofmemoryexception' thrown

which pointing line of code:

var table = newtonsoft.json.jsonconvert.deserializeobject<system.data.datatable>(data); 

not sure how fix it? can spot error or how fix it?...

thanks..

my controller is:

public async system.threading.tasks.task<actionresult> about()     {         string url = "https://restcountries.eu/rest/v1/region/africa";          using (system.net.http.httpclient client = new system.net.http.httpclient())         {             client.baseaddress = new uri(url);             client.defaultrequestheaders.accept.clear();             client.defaultrequestheaders.accept.add(new system.net.http.headers.mediatypewithqualityheadervalue("application/json"));              system.net.http.httpresponsemessage response = await client.getasync(url);             if (response.issuccessstatuscode)             {                 var data = await response.content.readasstringasync();                 var table = newtonsoft.json.jsonconvert.deserializeobject<system.data.datatable>(data);                  system.web.ui.webcontrols.gridview gview = new system.web.ui.webcontrols.gridview();                 gview.datasource = table;                 gview.databind();                 using (system.io.stringwriter sw = new system.io.stringwriter())                 {                     using (system.web.ui.htmltextwriter htw = new system.web.ui.htmltextwriter(sw))                     {                         gview.rendercontrol(htw);                         viewbag.returneddata = sw.tostring();                     }                 }             }         }         return view(); 

you shouldn't deserializing datatable. datatable generic, in-memory representation of relational data. following deserialization lines of code have:

var data = await response.content.readasstringasync(); var table = newtonsoft.json.jsonconvert.deserializeobject<system.data.datatable>(data); 

you asking .net code go grab data internet , turn string of data in-memory representation of relational data, when, @ point, it's string of characters.

you should create model of country properties returned api you're querying.

you can deserialize data , play in .net doing following:

newtonsoft.json.jsonconvert.deserializeobject<ilist<mycountrymodel>>(data);
