I already have two working bots in Wikipedia, but they use different method. Currently, I am trying to create a bot using C#. On the API documentation page, they have provided some sample codes in java, PHP, and python. But unfortunately, they haven't provided any sample code in C#. It is the only language I am familiar with.
This is the Wikimedia API:Edit documentation page. Would someone kindly convert the few words from java (or any other language) to C#?
If I could get only this code converted to C#, I can build the rest of the bot by myself. I asked help on the relevant noticeboard(s) on the wikimedia site(s), but nobody there is familiar with C#. That's why I am now asking this outside of wikipedia.
Thanks a lot in advance
This is the java source-code:

// Start From Step 1
getLoginToken();I can't go so deeply but I hope you can take a look at this page and find out how to do it
https://docs.microsoft.com/en-us/dotnet/api/system.net.http.httpclient?view=net-6.0
You can try something like this
private static async Task LoginRequest(string loginToken)
{
var data = new
{
action = "login",
lgname = "bot_username",
lgpassword = "bot_password",
lgtoken = loginToken,
format = "json"
};
using (var client = new HttpClient())
using (var response = await client.PostAsJsonAsync(LOGIN_URL, data))
{
var responseString = await response.Content.ReadAsStringAsync();
var responseObject = JsonConvert.DeserializeObject<JObject>(responseString);
Console.WriteLine(responseObject);
}
}
private static async Task<string?> GetLoginToken()
{
var url = $"{LOGIN_URL}?action=query&meta=tokens&type=login&format=json";
using (var client = new HttpClient())
using (var response = await client.GetAsync(url))
{
var responseString = await response.Content.ReadAsStringAsync();
var responseObject = JsonConvert.DeserializeObject<JObject>(responseString);
return responseObject?["query"]?["tokens"]?["logintoken"]?.ToString();
}
}
For converting the response you need
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
You can call these methods from your Main method like this:
const string LOGIN_URL = "https://test.wikipedia.org/w/api.php";
public static async Task Main()
{
var loginToken = await GetLoginToken();
await LoginRequest(loginToken ?? throw new Exception("No login token."));
}
