方法一:使用代理类的方式

Service提供很简单,就一个方法

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;

namespace WebServiceTest.Service1
{
    /// <summary>
    /// Summary description for OceanTest
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
    public class OceanTest : System.Web.Services.WebService
    {

        [WebMethod]
        public int Add(int i,int j)
        {
            return i + j;
        }
    }
}

Client添加引用,生成代理类

Config添加

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="OceanTestSoap" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:3721/OceanTest.asmx" binding="basicHttpBinding"
                bindingConfiguration="OceanTestSoap" contract="ServiceReference1.OceanTestSoap"
                name="OceanTestSoap" />
        </client>
    </system.serviceModel>
</configuration>

调用方式

            ServiceReference1.OceanTestSoapClient client = new ServiceReference1.OceanTestSoapClient(); 
            var x = client.Add(1, 2);

动态更改调用地址

            ServiceReference1.OceanTestSoapClient client = new ServiceReference1.OceanTestSoapClient();
            client.Endpoint.Address = new System.ServiceModel.EndpointAddress("http://localhost:3721/OceanTest.asmx");
            var x = client.Add(1, 2);

方法二:使用反射方法调用

调用方法

            string url = "http://localhost:3721/OceanTest.asmx";
            IList<object> list = new List<object>();
            list.Add(2);
            list.Add(5);
            object result = WSHelper.InvokeWebService(url, "Add", list.ToArray());
