4．7使用vb.net调用
无需下载任何组件
新建项目Visual Basic项目windows应用程序。
在解决方案资源管理器中添加web引用,输入wsdl文件所在地址。
将web引用改名为yundan.
yundan.（service_name）即可引用
*需引用System.web.services*
例程：
    Public Class Form1
        Inherits System.Windows.Forms.Form
#Region " Windows 窗体设计器生成的代码 "
    Public Sub New()
        MyBase.New()
        InitializeComponent()
    End Sub
    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
        If disposing Then
            If Not (components Is Nothing) Then
                components.Dispose()
            End If
        End If
        MyBase.Dispose(disposing)
    End Sub
    Private components As System.ComponentModel.IContainer

        Dim cc As yundan.Service1 = New yundan.Service1()
