我怎樣才能在窗口張貼JSON字符串與一些參數一起普遍應用C＃

Question

在通用的Windows應用程序的參數一起發佈JSON值

例如：

交 http://sampleurl?param=1&param2=1 JSON體：[{」關鍵 「：」 值」， 「KEY2」： 「值2」}]

Answer 1

，我們可以創建參數詞典，並張貼作爲formcontent

public static async Task<string> postdataAsync(Uri posturl, Dictionary<string, string> pairs) 
    { 
     string response = ""; 
     try 
     { 
      var filter = new HttpBaseProtocolFilter(); 
      filter.IgnorableServerCertificateErrors.Add(ChainValidationResult.Expired); 
      filter.IgnorableServerCertificateErrors.Add(ChainValidationResult.Untrusted); 
      filter.IgnorableServerCertificateErrors.Add(ChainValidationResult.InvalidName); 
      HttpClient httpClient = new HttpClient(filter); 
      Windows.Web.Http.HttpFormUrlEncodedContent formContent = new Windows.Web.Http.HttpFormUrlEncodedContent(pairs); 
      HttpResponseMessage httpresponse = await httpClient.PostAsync(posturl, formContent); 
      response = await httpresponse.Content.ReadAsStringAsync(); 
     } 
     catch 
     { 
      return null; 

     } 
     return response; 

    }
