客户端如何调用WebService并且POST数据

直接上代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;using System.Net;
using System.IO;
namespace ETCRM.WebService.Tester
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                //String Url = "http://localhost:3520/SynchDataInterface.asmx?op=SetSynchData";

                //WeService Address，需要注意的是SetSynchData是WebService中公开的方法，
                //不要用?op=SetSynchData，无法调用，提示500 内部错误
                String Url = "http://localhost:3520/SynchDataInterface.asmx/SetSynchData";
                byte[] dataArray = Encoding.Default.GetBytes("需要Post到Server-side的data");
                WebRequest req = WebRequest.Create(Url);
                req.Method = "POST";
                req.ContentLength = dataArray.Length;
                req.ContentType = "application/x-www-form-urlencoded";

                //创建输入流
                Stream dataStream = req.GetRequestStream();
                //发送请求
                dataStream.Write(dataArray, , dataArray.Length);
                dataStream.Close();

                //WebResponse res = req.GetResponse();// GetResponse blocks until the response arrives
                HttpWebResponse res = (HttpWebResponse)req.GetResponse();
                Stream receiveStream = res.GetResponseStream(); //Read the stream into a string
                StreamReader sr = new StreamReader(receiveStream);
                string resultstring = sr.ReadToEnd();
                Console.WriteLine(resultstring);
                Console.Read();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                Console.Read();
            }
        }
    }
}

只是一个Example，记录下来方便以后查阅，其他还需要注意的就是流的Close问题

需要注意编码问题，最好统一改成UIT-8

 byte[] dataArray = Encoding.UTF8.GetBytes(XmlObjectHelper.ObjectToXML(postData));
