The below method will be used to fulfill the below-mentioned scenario If a user wants a list of all Tutorials available, then the below code would need to be written to accomplish this. Run the Filddler tool and perform the below steps; Go to the composer section. Graphics Programming.
When all major platforms could access the Web using Web browsers, different platforms couldn't interact. For these platforms to work together, Web-applications were developed. Web-applications are simply applications that run on the web. These are built around the Web browser standards and can be used by any browser on any platform.
By using Web services, your application can publish its function or message to the rest of the world. Web services can offer application-components like: Web services can help to solve the interoperability problem by giving different applications a way to link their data.
With Web services you can exchange data between different applications and different platforms.

The web service would then need to return the Tutorial name which had the Tutorial id 1. This section of code is used to return the "Tutorial name" which has the Tutorial id passed to the web method. By default, what needs to be remembered is that whatever is passed to the URL in the browser is a string.
But you have to remember that the Index to our list has to be an integer, so we are adding the necessary code to first convert the Tutorialid to an Integer and then use it to access the index position in our list and Then return the value to the calling program accordingly. This method will be invoked whenever we want to add a string value to our list of Tutorials via the POST method.
Code Explanation: This allows the method to be invoked via the POST call. The second line of code is used to add the string value passed via the POST call to our existing list of Tutorial strings. TryParse Tutorialid, out pid ; 1st.
The Int32 function in code is used to convert the Tutorial ID from a string variable to an integer. Running your first Restful web service Now that we have created our entire web service in the above section.
Let's see how we can run the Tutorial service so that it can be invoked from any client. To run the web service, please follow the below steps Step 1 Right click on the Project file — Webservice.
This will ensure that this project is run when Visual Studio runs the entire solution Step 3 The next step is to run the project itself. Now depending on the default browser installed on the system, the appropriate browser name will come next to the run button in Visual Studio. In our case, we have Google Chrome showing up.
Just click on this button. In the above output, You can see that the browser is invoking the 'GET' verb and executing the 'GetAllTutorial' method in the web service.
This module is used to display all the Tutorials exposed by our web service. Testing your first Restful web service In the above section, we have already seen how to use the browser to execute the 'GET' verb and invoke the 'GetAllTutorial.
If you hit the enter button, you will get the below output Now you will see the output of Queues which actually corresponds to the number 1 in our list of Tutorial Strings. It also shows that the value of 1 is being passed successfully via the browser to our web service and to our method and that is why we are getting the correct corresponding value of "Queues" in the browser.
Next let's consume our web service by executing the below scenario. For this, you need to install the tool called "Fiddler" which is a free downloadable tool from the site.
Run the Filddler tool and perform the below steps; Go to the composer section. This is used to create requests which can be submitted to any web application.
Remember that our POST request method in our Web service only accepts json style data so we need to ensure this is specified when we are sending a request to our application. Finally, we need to enter our data. Remember that our method for POST accepts a parameter called 'str.
Finally, just click the Execute button in fiddler. Now, when we browse to the Tutorial URL to show all the strings in our Tutorial list, you will now see the value of "Trees" is also present. This shows that the POST request to the web service was successfully executed and that it was successfully added to our Tutorial List. Run the Filddler tool and perform the below steps Go to the composer section. Ensure that the id which is used to delete a string in the list sent via the URL as a parameter.
In our example, we are sending 1 so this will delete the 2 nd element in our collection which is "Queues". Now, when we browse to the Tutorial URL to show all the strings in our Tutorial list, you will notice that the value of "Queues" is no longer present. The element at index no 1 in our list of Tutorial strings was successfully deleted.
REST is used to build web services that are lightweight, maintainable, and scalable in nature.
