Read value from json string by string operation

Question

How to read "key" and "key1"'s value from below string. Its json but I can not parse as its very large number and its broke while parsing.

so, would like to read the somelongnumber and somelongnumber2 through string operation.

{key:somelongnumber,key1:somelongnumber2}

which would be the easiest way to get this value.

string with data:

{key:987680907568874555505607487995865555765995697489705794879988794489875875748987900769748746885877550977678595976099650577885777777684698859955669967959569775575067,key1:57069588960687005850750777094807006847879887980496989949579940779055857509947777847575786087598684799568577408880997966575750505586786988505685776878966949595807557508787784690576899698976897568855509907577566780999748589995405946407480098700854777748707067084789808075807709656084406888907505699899840957887847487008975787755684857507580057597799985874870997758507505954704880888999859760585587860777649885965487088048678878505979799046569808657874800555897997680907568874805607487995865555765995697489705794879988794489875875748987900769748746885877550977678455976099650577885777777684698859955669967959569775575067}

Answer 1

If you don't really want to deal with JSON serialization and DTO's and your only objective is to parse this input, you can try with something like this:

string myData = "YOUR JSON INPUT";
string[] mydata2 = myData.Trim('{').Trim('}').Split(',');
string firstVal = mydata2[0].Split(':')[1];
string secondVal = mydata2[1].Split(':')[1];

Although if you want a long term solution, better keep with JSON serialization.

Answer 2

Here is your class for deserializing

class JsonClass
{
    public System.Numerics.BigInteger Key1 {get; set;}
    public System.Numerics.BigInteger Key2 {get; set;}
}

For deserializing

var result = JsonConvert.DeserializeObject(inputJson);
Console.WriteLine(result.Key1);
