In the [documentaton](https://learn.microsoft.com/en-us/dotnet/fundamentals/networking/http/httpclient) there is an example how to use [GetJsonFormAsync](https://learn.microsoft.com/en-us/dotnet/api/system.net.http.json.httpclientjsonextensions.getfromjsonasync) to parse the result into a record class. — Klaus Gütter, Jul 09 '23 at 06:37

I like the previous solutions, but a straight forward answer would be:

 using System.Text.Json;

 ...

 string s = await httpClient.GetStringAsync(Home.BaseAddr + "LastID?pass=" + Password); 
 var obj = JsonSerializer.Deserialize<Tuple<string,string>>(s);

It is simple as that. Because the Tuple construct is defined with Item1, Item2 as properties and the deserialializer would map it on these.

To get the values:

string item1 = obj.Item1;
string item2 = obj.Item2;

One also could define custom class to deserialize it to. But that's what i would do ! :) – Michał Turczyn Jul 09 '23 at 07:35

If you have imported System.Net.Http.Json, you can use the GetFromJsonAsync<TValue>(HttpClient, Uri, CancellationToken) method to get the response body as Response instance.

using System.Net.Http.Json;

Response responce = await httpClient.GetFromJsonAsync<Response>(Home.BaseAddr + "LastID?pass=" + Password);

Otherwise, you should deserialize the JSON.

using Newtonsoft.Json;

string responceString = await httpClient.GetStringAsync(Home.BaseAddr + "LastID?pass=" + Password); 

Response responce = JsonConvert.DeserializeObject<Response>(responceString);

using System.Text.Json;

string responceString = await httpClient.GetStringAsync(Home.BaseAddr + "LastID?pass=" + Password); 

Response responce = JsonSerializer.Deserialize<Response>(responceString);

public class Response
{
    public string Item1 { get; set; }
    public string Item2 { get; set; }
}
