Introduction

In this article, we will walk you through the process of creating a random quote generator using Blazer server app. This project will be fairly simple, with just a button to generate a quote and a display area to show the generated quote. We will start by creating a new Blazer server app and then dive into the code to implement the functionality.

Creating a New Blazer Server App

To begin, let's create a new Blazer server app project. You can choose any name for the project. In this case, we'll refer to it as "Blazer App 7". Select the ".NET 6" framework as it is the long-term supported version. Once the project is created, navigate to the "Pages" folder and open the "Index.razor" page. This will be our front page where we'll add the logic and HTML markup.

Setting Up the Front Page

Start by removing the existing HTML content from the "Index.razor" page, leaving only the page title. Modify the title to "Quote Generator". Next, add a button with the text "Generate Quote". Below the button, add an H1 tag to display the current quote. We'll use a variable called "currentQuote" to store and display the quote. For now, let's leave it empty as we'll populate it with a random quote later on.

Generating Quotes

Creating the Quote Array

To store the quotes, we need to create an array of strings. Declare a public string array variable called "quotes" and initialize it with a set of quotes that you want to choose from. You can add as many quotes as you like.

Generating a Random Quote

To generate a random quote, we'll use the Random class. Create an async method called "GenerateRandomQuote" that returns a task. Inside this method, instantiate a new instance of the Random class and store it in a variable called "random". To select a random index from the string array, use the "random.Next" method, passing in the minimum and maximum values. Since arrays are zero-based, set the minimum value as 0 and the maximum value as "quotes.Length - 1". This will ensure that we select a random index within the range of the array.

Updating the UI

After selecting a random quote, we need to update the UI to display the new quote. Invoke the "StateHasChanged" method to update the UI asynchronously. This will refresh the page and show the newly generated quote in the "currentQuote" variable.

Testing the Random Quote Generator

To test the random quote generator, run the application. Click on the "Generate Quote" button and observe the display area. You should see a random quote being generated each time you click the button. Note that if you have a limited number of quotes in the array, some quotes may repeat.

Conclusion

Congratulations! You have successfully created a random quote generator using Blazer server app. This project serves as a great opportunity to learn more about Blazer and enhance your logical thinking skills. Have fun exploring new functionalities and customizations to make the quote generator even more interactive and engaging.
