如何在httpClient中发布参数，而在Postman中使用参数

Question

我想用 HttpClient 发布我的参数。 httpclient请求体中的内容是什么？我把它写在正文部分，当我运行该项目时，我收到错误：

我的代码是：

string baseAddress = "https://WebServiceAddress";
Client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", token);
HttpRequestMessage bodyRequest = new HttpRequestMessage(HttpMethod.Post, baseAddress)

bodyRequest.Content = new StringContent(JsonConvert.SerializeObject(Prescriptionrequest), Encoding.UTF8, "application/json");

var responseApi = Client.PostAsync(baseAddress, bodyRequest.Content, new System.Threading.CancellationToken(false));

bodyRequest.Content

的格式应该是什么？

使用此代码：

HttpClient client = new HttpClient();
var dictionary = new Dictionary<string, string> 
{    
    { "parameter0", "value0" },    
    { "parameter1", "value1" }
};    
var content = new FormUrlEncodedContent(dictionary);    
var response = await client.PostAsync("https://WebServiceAddress", content);    
var responseString = await response.Content.ReadAsStringAsync();
