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 Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Collections.Generic; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.ComponentModel; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Data; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Drawing; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Linq; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Text; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Windows.Forms; namespace WinFormClient { public partial class Form1 : Form { public Form1() { InitializeComponent(); this.combo<a href="/tag/Box/" target="_blank" class="keywords">Box</a>1.Items.Add("+"); this.combo<a href="/tag/Box/" target="_blank" class="keywords">Box</a>1.Items.Add("-"); this.combo<a href="/tag/Box/" target="_blank" class="keywords">Box</a>1.Items.Add("*"); this.combo<a href="/tag/Box/" target="_blank" class="keywords">Box</a>1.Items.Add("/"); this.combo<a href="/tag/Box/" target="_blank" class="keywords">Box</a>1.Items.Add("power"); this.combo<a href="/tag/Box/" target="_blank" class="keywords">Box</a>1.Items.Add("sin"); this.combo<a href="/tag/Box/" target="_blank" class="keywords">Box</a>1.Items.Add("cos"); } private void button1_Click(object sender,EventArgs e) { double num1 = Double.Parse(this.text<a href="/tag/Box/" target="_blank" class="keywords">Box</a>1.Text.Trim()); double num2 = Double.Parse(this.text<a href="/tag/Box/" target="_blank" class="keywords">Box</a>2.Text.Trim()); string oper = this.combo<a href="/tag/Box/" target="_blank" class="keywords">Box</a>1.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.text<a href="/tag/Box/" target="_blank" class="keywords">Box</a>3.Text = result + ""; } private void combo<a href="/tag/Box/" target="_blank" class="keywords">Box</a>1_Selecte<a href="/tag/dind/" target="_blank" class="keywords">dind</a>exChanged(object sender,EventArgs e) { string oper = this.combo<a href="/tag/Box/" target="_blank" class="keywords">Box</a>1.Text; if (oper.Equals("sin") || oper.Equals("cos")) { this.text<a href="/tag/Box/" target="_blank" class="keywords">Box</a>2.Visible = false; } else { this.text<a href="/tag/Box/" target="_blank" class="keywords">Box</a>2.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
