C# - Converting JSON to C# Array -


i new c# , have little problem. have json-file includes mailadresses. each mailadress there 4 fields (name, email[], imprint, info2) in json-file. want convert array or arraylist in project , using newtonsoft.json achieve this.

i made class adress : 

public class adress {     public string name = "";     public string[]  email = {""};     public string imprint = "";     public string info2 = ""; }

this json:

{"name":"test1","email":["test1@test.de"],"imprint":"testimprint1 testimprint1","info2":"testinfo1"} {"name":"test2","email":["test2@test.de"],"imprint":"testimprint2 testimprint2","info2":"testinfo2"} {"name":"test3","email":["test3@test.de"],"imprint":"testimprint3 testimprint3","info2":"testinfo3"}

and try converting this: 

list<adress> adresses = new list<adress>(); string json_adress = file.readalltext("c:\\mail\\adresses.json"); adresses = jsonconvert.deserializeobject<list<adress>>(json_adress);

i following error:

"cannot deserialize current json object (e.g. {"name":"value"}) type 'system.collections.generic.list1[mailer.adress]' because type requires json array (e.g. [1,2,3]) deserialize correctly."`

maybe can me understand json-thing better?

you there small mistake. supplied following. please take notice there no commas @ seperation.

{jsonstuff} {jsonstuff} {jsonstuff}

but following says want converted list<address> not list :(

jsonconvert.deserializeobject<list<adress>>(json_adress);

so in fact need supply list of address,

[     {jsonstuff},     {jsonstuff},     {jsonstuff}, ]

please not forget commas :)

[{"name":"test1","email":["test1@test.de"],"imprint":"testimprint1 testimprint1","info2":"testinfo1"}, {"name":"test2","email":["test2@test.de"],"imprint":"testimprint2 testimprint2","info2":"testinfo2"}, {"name":"test3","email":["test3@test.de"],"imprint":"testimprint3 testimprint3","info2":"testinfo3"}]

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
