The initialization requires 5 parameters, which are all string type:

You can preview the whole process by the gif image below.

How to integrate

Open the login window

var login = new Login();
// Trigger when login succeeded, you will receive auth code in event handler
login.CodeReceived += Login_CodeReceived;
login.ShowDialog();

Use auth code to get the user info

public async Task<string?> RequestToken(string clientId, string clientSecret, string code)
{
    var body = new
    {
        grant_type = "authorization_code",
        client_id = clientId,
        client_secret = clientSecret,
        code
    };

    var req = new RestRequest(_requestTokenUrl).AddJsonBody(body);
    var token = await _client.PostAsync<TokenDto>(req);

    return token?.AccessToken;
}

public async Task<UserDto?> GetUserInfo(string token)
{
    var req = new RestRequest(_getUserInfoUrl).AddQueryParameter("accessToken", token);

    return await _client.GetAsync<UserDto>(req);
}

...

var token = await _casdoorApi.RequestToken(
    CasdoorVariables.ClientId,
    CasdoorVariables.ClientSecret,
    authCode
);

var user = await _casdoorApi.GetUserInfo(token);
