DOTNET下的三种调用webservice方式之WinForm调用方式

上两篇分别采用了ASP.NET和javascript两种方式调用webservice

回顾上两篇内容

DOTNET下的三种调用webservice方式之ASP.NET调用方式

DOTNET下的三种调用webservice方式之Javascript调用方式

这篇我们将采用WinForm程序来调用webservice

新建一个Windows窗体应用程序，我取名为WinFormClient

这里也必须添加web引用，将网址：http://localhost/WebServiceApp/CalcService.asmx 填入框中

取名为WinformService

开发界面如下

后台代码为

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WinFormClient
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            this.comboBox1.Items.Add("+");
            this.comboBox1.Items.Add("-");
            this.comboBox1.Items.Add("*");
            this.comboBox1.Items.Add("/");
            this.comboBox1.Items.Add("power");
            this.comboBox1.Items.Add("sin");
            this.comboBox1.Items.Add("cos");
        }
        private void button1_Click(object sender, EventArgs e)
        {
            double num1 = Double.Parse(this.textBox1.Text.Trim());
            double num2 = Double.Parse(this.textBox2.Text.Trim());
            string oper = this.comboBox1.Text;
            double result = 0;

            WinformService.CalcServiceSoap service = new WinformService.CalcServiceSoapClient();
            switch (oper)
            {
                case "+":
                    result = service.Add(num1, num2);
                    break;
                case "-":
                    result = service.Minus(num1, num2);
                    break;
                case "*":
                    result = service.Multiply(num1, num2);
                    break;
                case "/":
                    result = service.Devide(num1, num2);
                    break;
                case "power":
                    result = service.Power(num1, (int)num2);
                    break;
                case "sin":
                    result = service.Sin(num1);
                    break;
                case "cos":
                    result = service.Cos(num1);
                    break;
                default:
                    result = service.Add(num1, num2);
                    break;
            }
            this.textBox3.Text = result + "";
        }
        private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            string oper = this.comboBox1.Text;
            if (oper.Equals("sin") || oper.Equals("cos"))
            {
                this.textBox2.Visible = false;
            }
            else
            {
                this.textBox2.Visible = true;
            }
        }
    }
}

这里着重看的代码是

WinformService.CalcServiceSoap service = new WinformService.CalcServiceSoapClient();

创建了一个webservice的实例

好了，到这里，三种方式都写完了，最后把解决方案项目视图贴上来
