Answer 1

但是，如果您可以使用HttpClient，您爲什麼要使用WebClient。要使用HttpClient，您只需從Microsoft自身添加this lib即可。

代碼HttpClient

 HttpClient objClient = new HttpClient(); 
     MultipartFormDataContent form = new MultipartFormDataContent(); 
     form.Add(new StringContent("password text"), "Password key"); 
     form.Add(new StringContent("userID text"), "userID key"); 

     var response = await objClient.PostAsync(new Uri("URI string", UriKind.Absolute), form); 

希望幫助.. !!
