Send by value in Body with HttpClient class

Hi Guys, I'd like to know how can I send (post) data in body with bearer? I try to use HttpClient, but, I don't know how to load in body my informations. When I use Postman, I can send, but when I need to send it through C# I don't know how to send it. I try two ways:

        var objAnonymous = new { 
            prop1 = "prop1",
            prop2 = "prop2",
            prop3 = "prop3",
            prop4 = "prop4",
            prop5 = "prop5"
        };
        var objString = JsonConvert.SerializeObject(objAnonymous);
        var request = new HttpRequestMessage(HttpMethod.Post, "url");
        request.Content = new StringContent(objString, Encoding.UTF8);
        request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
        request.Headers.Authorization =
            new AuthenticationHeaderValue("Bearer", token);
           var response = await httpClient.SendAsync(request);
        response.EnsureSuccessStatusCode();
        
        var result = await response.Content.ReadAsStringAsync();

        var objAnonymous = new { 
            prop1 = "prop1",
            prop2 = "prop2",
            prop3 = "prop3",
            prop4 = "prop4",
            prop5 = "prop5"
        };
        var objString = JsonConvert.SerializeObject(objAnonymous);
        var request = new HttpRequestMessage(HttpMethod.Post, "url");
        request.Content = new StringContent(objString, Encoding.UTF8);
        request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
        request.Headers.Authorization =
            new AuthenticationHeaderValue("Bearer", token);
           var response = await httpClient.SendAsync(request);
        response.EnsureSuccessStatusCode();
        
        var result = await response.Content.ReadAsStringAsync();

and

        HttpClient httpClient = new HttpClient();

        var objAnonymous = new { 
            prop1 = "prop1",
            prop2 = "prop2",
            prop3 = "prop3",
            prop4 = "prop4",
            prop5 = "prop5"
        };

        var objString = JsonConvert.SerializeObject(objAnonymous);

        httpClient.DefaultRequestHeaders.Authorization =
            new AuthenticationHeaderValue("Bearer", "token");
        var content = new StringContent(objString, Encoding.UTF8, "application/json");
        var response = await httpClient.PostAsync("url", content);
        response.EnsureSuccessStatusCode();
        var result = await response.Content.ReadAsStringAsync();

        HttpClient httpClient = new HttpClient();

        var objAnonymous = new { 
            prop1 = "prop1",
            prop2 = "prop2",
            prop3 = "prop3",
            prop4 = "prop4",
            prop5 = "prop5"
        };

        var objString = JsonConvert.SerializeObject(objAnonymous);

        httpClient.DefaultRequestHeaders.Authorization =
            new AuthenticationHeaderValue("Bearer", "token");
        var content = new StringContent(objString, Encoding.UTF8, "application/json");
        var response = await httpClient.PostAsync("url", content);
        response.EnsureSuccessStatusCode();
        var result = await response.Content.ReadAsStringAsync();

in your code you use StringContent, but in postman you seem to be using form-data have you tried using FormUrlEncodedContent instead, maybe?
