ASP.NET Rozor VB Logic:

Sure! In ASP.NET Razor, you can use VB.NET syntax to write server-side logic within your web pages. Let's break it down with a simple example:

Suppose you have a Razor page named "Greeting.vbhtml".

In this example:

• We use the @{ ... } block to write VB.NET logic.
• Inside the block, we declare variables name and greeting.
• We use a conditional statement (If...Then...Else) to determine the appropriate greeting based on the current time of day.
• Finally, we use @greeting, @name! to output the dynamic greeting and name within the HTML.

When this page is rendered in a web browser, it will greet the user with "Good Morning", "Good Afternoon", or "Good Evening" depending on the time of day, along with the name "John".

This demonstrates how you can use VB.NET syntax to write server-side logic within ASP.NET Razor pages.

The If Condition:

Certainly! In ASP.NET Razor using VB.NET syntax, you can use the If condition to perform conditional logic. Here's how you can use it:

In this example:

• We declare a variable age with a value of 20.
• We declare a variable message to store the result of the If condition.
• Inside the If condition, we check if the age is greater than or equal to 18.
• If the condition is true, we set the message variable to "You are an adult." Otherwise, we set it to "You are a minor."
• Finally, we output the message variable within the HTML markup.

This will display "You are an adult." because the age is greater than or equal to 18.

You can also use ElseIf to handle additional conditions and Else to handle all other cases not covered by the previous conditions.

The Else Condition

In ASP.NET Razor using VB.NET syntax, you can use the Else condition to execute a block of code when the If condition evaluates to false. Here's an example demonstrating the use of the Else condition:

In this example:

• We declare a variable hour to store the current hour of the day.
• We declare a variable greeting to store the appropriate greeting message based on the time of day.
• Inside the If-Else condition, we check the current hour. If it's less than 12, we set the greeting variable to "Good morning!". If it's between 12 and 18, we set it to "Good afternoon!". Otherwise, we set it to "Good evening!" using the Else condition.
• Finally, we output the greeting variable within the HTML markup.

This will display a greeting message based on the current time of day. If it's before 12 PM, it will display "Good morning!", if it's between 12 PM and 6 PM, it will display "Good afternoon!", and if it's after 6 PM, it will display "Good evening!".

The ElseIf Condition

In ASP.NET Razor using VB.NET syntax, you can use the ElseIf condition to handle multiple conditions in a sequence. Here's an example demonstrating the use of the ElseIf condition:

In this example:

• We declare a variable temperature to store the current temperature.
• We declare a variable weatherCondition to store the weather condition based on the temperature.
• Inside the If-ElseIf condition, we check the temperature variable against multiple conditions using ElseIf. Depending on the temperature range, we set the weatherCondition variable accordingly.
• If none of the conditions match, the Else block is executed.
• Finally, we output the weatherCondition variable within the HTML markup.

This will display the weather condition based on the current temperature. If the temperature is less than 10, it will display "Cold", if it's between 10 and 20, it will display "Mild", if it's between 20 and 30, it will display "Warm", and if it's 30 or above, it will display "Hot"
