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
