C# Web Service Howto

· 技术 · 2 分钟阅读

为项目组写了几个Howto的Case。

本文描述了一个用C#实现了在Windows Form或者Windows Console下调用Web Service的例子。 这是一个较复杂的例子。解决方案由三个项目组成：

  • **ClassLibrary：**定义了两个自定义类，编译成Windows Class Library(DLL)，并由另外两个项目引用
  • **WebServiceHowto：**Web Service的实现，主要是一个GetStudent的WebMethod，接受一个自定义类Dorm为参数，返回另一个自定义类Student。
  • **UseWebServiceHowto：**Windows Console(也可以是Windows Form)，实现一个Proxy，通过添加Service Reference调用Web Service。

1. ClassLibrary Dorm.cs

using System; using System.Collections.Generic; using System.Text; using System.Xml.Serialization;

namespace ClassLibrary {

public class Dorm
{

    public string Name;

    public string Number;
}

}

Student.cs

using System; using System.Collections.Generic; using System.Text; using System.Xml.Serialization;

namespace ClassLibrary {

public class Student
{

    public long Number;

    public string Name;

    public bool enabled;

    public Dorm dorm;
}

}

2. WebServiceHowto ITSTestService.asmx.cs

using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Web; using System.Web.Services; using System.Web.Services.Protocols; using ClassLibrary;

namespace WebServiceHowto { /// /// Summary description for ITSTestService ///

public class ITSTestService : System.Web.Services.WebService
{

    public string HelloWorld()
    {
        return "Hello World";
    }

    public Student GetStudent(Dorm d)
    {
        Student student = new Student();

        student.dorm = d;
        student.enabled = true;
        student.Number = 222222;
        student.Name = "maojun";

        return student;
    }
}

}

3. UseWebServiceHowto Program.cs

using System; using System.Collections.Generic; using System.Text; using ClassLibrary;

namespace UseWebServiceHowto { class Program { static void Main(string[] args) { WebServiceProxy proxy = new WebServiceProxy(); Dorm dorm = new Dorm();

        dorm.Name = "geng der drom";
        dorm.Number = "16-501-5";

        Student s = proxy.GetStudent(dorm);
        Console.WriteLine("Student Name={0}, Dorm={1}", s.Name, s.dorm.Name);
    }
}

}

WebServiceProxy.cs

using System; using System.Collections.Generic; using System.Text; using System.Web.Services.Protocols; using System.Web.Services; using System.Diagnostics; using System.ComponentModel; using ClassLibrary;

namespace UseWebServiceHowto {

class WebServiceProxy : SoapHttpClientProtocol
{
    public WebServiceProxy()
    {
        base.Url = "http://localhost:3489/ITSTestService.asmx";
    }

    public Student GetStudent(Dorm d)
    {
        return (Student)base.Invoke("GetStudent", new object[] { d });
    }
}

}
