c#調用WebAPI和WebService的方法

1.調用WebAPI

方法1.多個參數

 /// <summary>
        /// 使用POST方式發送json字符串請求結果
        /// </summary>
        /// <param name="url">url地址</param>
        /// <param name="postData">需要發送的json字符串</param>
        /// <returns></returns>
        public static string PostUrl1(int cmd, string url, string postData, string postData1)
        {
            string mturl = "";
            string result = "";
           // var request = (HttpWebRequest)WebRequest.Create(url);
            switch (cmd)
            {
                case 1:
                    
                    string param = HttpUtility.UrlEncode("CheckInfo") + "=" + HttpUtility.UrlEncode(postData);
                    byte[] bytes = Encoding.UTF8.GetBytes(param);

                    var request = (HttpWebRequest)WebRequest.Create(url + "/" + "CheckRoute");
                    request.Method = "POST";
                    request.ContentType = "application/x-www-form-urlencoded";
                    request.ContentLength = bytes.Length;
                    int length = bytes.Length;
                    request.ContentLength = length;
                    Stream writer = request.GetRequestStream();
                    writer.Write(bytes, 0, length);
                    writer.Close();
                    var response = (HttpWebResponse)request.GetResponse();
                    //var responseString = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8")).ReadToEnd();
                    //result = responseString.ToString();

                    Stream stream = response.GetResponseStream();        //獲取響應流
                    XmlTextReader Reader = new XmlTextReader(stream);
                    Reader.MoveToContent();
                    result = Reader.ReadInnerXml();

                    break;
                case 2:

                    string param1 = HttpUtility.UrlEncode("TestResult") + "=" + HttpUtility.UrlEncode(postData) + "&" + HttpUtility.UrlEncode("ItemResult") + "=" + HttpUtility.UrlEncode(postData1);
                   
                    byte[] bytes1 = Encoding.UTF8.GetBytes(param1);

                    var request1 = (HttpWebRequest)WebRequest.Create(url + "/" + "TestResultUpload");
                    request1.Method = "POST";
                    request1.ContentType = "application/x-www-form-urlencoded";
                    request1.ContentLength = bytes1.Length;
                    int length1 = bytes1.Length;
                    request1.ContentLength = length1;
                    Stream writer1 = request1.GetRequestStream();
                    writer1.Write(bytes1, 0, length1);
                    writer1.Close();
                    var response1 = (HttpWebResponse)request1.GetResponse();
                    //var responseString = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8")).ReadToEnd();
                    //result = responseString.ToString();

                    Stream stream1 = response1.GetResponseStream();        //獲取響應流
                    XmlTextReader Reader1 = new XmlTextReader(stream1);
                    Reader1.MoveToContent();
                    result = Reader1.ReadInnerXml();
                    break;
            }

            //MessageBox.Show(responseString.ToString());
            return result;
        }

方法2.

        /// <summary>
        /// 使用POST方式發送json字符串請求結果
        /// </summary>
        /// <param name="url">url地址</param>
        /// <param name="postData">需要發送的json字符串</param>
        /// <returns></returns>
        public static string PostUrl1(int cmd,string url, string postData)
        {
            string mturl = "";
            string result = "";
            switch (cmd)
            {
                case 1:
                    mturl = url + "/checkworkstation";
                    break;
                case 2:
                    mturl = url + "/savetestresult";
                    break;
            }

  
            //json參數

            var request = (HttpWebRequest)WebRequest.Create(mturl);
            request.Method = "POST";
            request.ContentType = "application/json";
            byte[] byteData = Encoding.UTF8.GetBytes(postData);
            int length = byteData.Length;
            request.ContentLength = length;
            Stream writer = request.GetRequestStream();
            writer.Write(byteData, 0, length);
            writer.Close();
            var response = (HttpWebResponse)request.GetResponse();
            var responseString = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8")).ReadToEnd();
            result = responseString.ToString();
            //MessageBox.Show(responseString.ToString());

            return result;
        }

2.調用Webervice
