HttpClient - PostAsJsonAsync

Question

當我使用PostAsJsonAsync<T>(..)擴展方法時遇到了一個簡單但令人討厭的問題，我找不到有關在任何地方解決以下問題的信息。

我的問題是，生成的Json使用PascaCasing，我需要camelCasing根據實際的標準。

下面是一個簡單的示例，可以重現問題（來源：http://www.codeproject.com/Articles/611176/Calling-ASP-NET-WebAPI-using-HttpClient）：

 HttpClient client = new HttpClient(); 
     client.BaseAddress = new Uri("http://localhost:56851/"); 

     client.DefaultRequestHeaders.Accept.Add(
      new MediaTypeWithQualityHeaderValue("application/json")); 

     var user = new Users(); 

     user.FirstName = txtFirst.Text; 
     user.Company = txtCompany.Text; 
     user.LastName = txtLas.Text; 
     user.Email = txtEmail.Text; 
     user.PhoneNo = txtPhone.Text; 
     user.Email = txtEmail.Text; 

     var response = client.PostAsJsonAsync("api/User", user).Result; 

     if (response.IsSuccessStatusCode) 
     { 
      MessageBox.Show("User Added"); 
      txtFirst.Text = ""; 
      txtLas.Text = ""; 
      txtPhone.Text = ""; 
      txtEmail.Text = ""; 
      txtCompany.Text = ""; 
      GetData(); 
     } 
     else 
     { 
      MessageBox.Show("Error Code" + 
      response.StatusCode + " : Message - " + response.ReasonPhrase); 
     }

嘗試只發送匿名類型。

var user = new { 
    firstName = txtFirst.Text, 
    company = txtCompany.Text, 
    lastName = txtLas.Text, 
    email = txtEmail.Text, 
    phoneNo = txtPhone.Text, 
    email = txtEmail.Text 
}; 
var response = client.PostAsJsonAsync("api/User", user).Result;
