webservice的两种调用方式

大佬教程收集整理的这篇文章主要介绍了webservice的两种调用方式，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

如下

service;
using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.serviceModel;
using System.serviceModel.ChAnnels;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
using System.Xml.serialization;
namespace ConsoleApplication1

{

class Program

{

static void Main(String[] args)

{

Hashtable ht = new Hashtable();

ht.Add("customer",new Customer { Id = 1 });

ht.Add("code",1);

var result = WebserviceCaller.QuerySoapWebservice("http://localhost:49644/TestWebService.asmx","HelloWorld",ht);
        Uri uri = new Uri("http://localhost:49644/TestWebservice.asmx");

        BasichttpSecuritymode securitymode = uri.scheR_779_11845@e.Equals("https",StringComparison.InvariantCultureIgnoreCasE) ? BasichttpSecuritymode.Transport : BasichttpSecuritymode.None;
        BasichttpBinding binding2 = new BasichttpBinding(securitymodE);
        binding2.MaxReceivedmessageSize = int.MaxValue;
        binding2.Name = "TestWebserviceSoap";
        binding2.ReaderQuotas = new XmlDictionaryReaderQuotas() { MaxStringContentLength = int.MaxValue };

        CustomBinding binding = new CustomBinding();
        binding.Name = "TestWebserviceSoap12";
        binding.Elements.Add(new TextmessageEncodingBindingElement()
        {
            messageVersion = messageVersion.Soap12,ReaderQuotas = new XmlDictionaryReaderQuotas() { MaxStringContentLength = int.MaxValue }
        });
        binding.Elements.Add(new httpTransportBindingElement());


        TestWebserviceSoapClient svc = new TestWebserviceSoapClient(binding,new EndpointAddress(uri));
        var str = svc.HelloWorld(new TestWebservice.Customer() { Id = 1 },code: 1);
    }

}

public class Customer
{
    public int id { get; set; }
}

/// <sumMary>
/// 利用Webrequest/WebResponse进行Webservice调用的类
/// </sumMary>
public class WebserviceCaller

    #region Tip:使用说明
    //webservices 应该支持Get和Post调用，在web.config应该增加以下代码
    //<webservices>
    // <protocols>
    //  <add name="httpGet"/&gt;
    //  <add name="httpPost"/&gt;
    // </protocols>
    //</webservices>

    //调用示例：
    //Hashtable ht = new Hashtable(); //Hashtable 为webservice所需要的参数集
    //ht.Add("str","test");
    //ht.Add("b","true");
    //XmlDocument xx = WebSvcCaller.QuerySoapWebservice("http://localhost:81/service.asmx",ht);
    //messageBox.Show(xx.outerXml);
    #endregion
