问2021年在c#中提出简单的非异步post请求

EN

var client = new HttpClient();
            
    var webRequest = new HttpRequestMessage(HttpMethod.Post, "http://your-api.com")
    {
        Content = new StringContent("{ 'some': 'value' }", Encoding.UTF8, "application/json")
    };

    var response = client.Send(webRequest);

    using var reader = new StreamReader(response.Content.ReadAsStream());
            
    return reader.ReadToEnd();
}
