    This article will help you create a web service called MathService that shows methods for adding, subtracting, dividing, and multiplying two numbers.

    Requirements

    The following list lists the recommended hardware, software, skills, and knowledge you’ll need:

  • Microsoft Windows
  • Internet Information Server
  • Visual Studio .NET

    • How do I access web services?

    Go to Options->Settings->Services.Press F4 (or Edit->Create Line) to open the line.Name your own web service.In the Server column, zoom in to select SOAP.Press Alt+Enter to access the server properties.In the WSDL URL field, enter the URL of the WSDL you are accessing.

    This article assumes you are familiar with: How to use the Visual Studio .NET IDE.

    Write .asmx Web Service

    Can we use Web service in Windows application?

    Add an important web link to the app Then click on “Add Web Link”. A new window frame will open. Then, in the URL, pasteo links to the service. (For example: http://localhost:65312/WebServiceSample/Airthmatic.asmx) Immediately after that, click on the Go button.

    Open Studio Visual .NET.

    From the File menu, select New and browse to the project. Under Project Types, select Visual C# Projects. Then select ASP.NET Web Service for Templates. Enter MathService in the Location field in the SMS field to change the default alias (WebService1) to MathService.

  • Change the default name, I wouldsaid, web service created from Service1.asmx, on MathService.asmx.Click

  • Select to switch to Exchange view in development environment.

  • Define methods that encapsulate the functionality of your service. Each method exposed by a service must be preceded by a specific WebMethod attribute. Without the element, the method is not fired by the service.

    How do I add a service reference in Windows app?

    In Solution Explorer, right-click the tag of the project where you want to add the service and select Add Service Reference. The Add Service Reference dialog box appears. In the Address field, enter the service URL, then click Go to find the service.

    Note

    Not all methods need to support the WebMethod attribute. This is useful for hiding some of the implementation details called by forensic web service methods, or for the truth that the WebService class is shared across local applications. A local installation can use any public class, but mostly the WebMethod methods are available remotely as web services.

    Add the following method to the MathServices class you created:

    [web method]public int Add(int a, int b) return(a+b);[Web method]public System.Single Subtract (System.Single A, System.Single B)  Recovery (A - System B);[Web method]public.Single Multiplier(System.Single A, System.B) single return A*B;[Web method]public System.Single Divide(System.Single A, System.Single B)  if (B == 0) returns -1; return Convert./tosingle(a B);

  • Choose Build from the Build menu to make building your web service easier.

  • Open the MathService.Web asmx service page to test the network service. If you specify a local machine or laptop to host the page, the URL will most likely be http://localhost/MathService/MathService.asmx.

    • The ASP.NET runtime returns a web help service page that describes the site. You can also test different methods of the web service on this page.

    Use One Web Service

    1. Open Visual Studio .NET.

    2. How do I add a Web service reference to a web application?

      How to add a web link You can also open the Add Web Link dialog in the Solution Explorer area by right-clicking on Links and selecting Add Web Link. In the Web Link Subject field, rename the web link to ExcelWebService. Click Add Reference to add a web source for the target web service.

      In the Project Types section, select Visual C# Projects, and then in the Templates section, select Console Application.

    3. Add a reference to the entire global MathService to the new application console. Step

      This marks the proxy class on the user’s machine. Once the proxy class is created, people can create objects based on the defined class. Each method call made that contains the object then navigates to that service’s Uniform Resource Identifier (URI) inwebsite (usually in the form of a SOAP request).

      1. On the Project menu, choose Add Web Link.
      2. In the Add Web Link dialog box that appears, enter the actual URL of the web service in the Address text box and press Enter. If you are setting the local machine host for a web service, the URL is usually http://localhost/MathService/MathService.asmx.
      3. Choose Add Link. You can also enter the URL of the discovery file (MathService.vsdisco) or provide web links to the local web server in the left pane to select one of our MathServices from the list.
      4. Expand the Web Links section in Solution Explorer and indicate that this namespace was used.

    4. Instance the created proxy object. Place the following code in the current function named Main:

      localhost.Service1 myMathService = new localhost.Service1();

    5. Call the actual method on the proxy object created in the previous step instead of the following:

      Console.Write("2 + 4 = MyMathService 0",.Add(2,4));

    6. Choose Build from the Build menu to create the requirements console.

    7. SelectGo to Start in the Debug menu to test the application.

    8. Close and save the current project.
