To apply ASP.NET Razor with C# logic, you typically follow these steps:
Create a Razor Page: First, create a Razor (.cshtml) file within your ASP.NET project. This file will contain both HTML and C# code.
Embed C# Code: Use the @
symbol to denote C# code within your Razor page. You can embed C# code directly within HTML elements or within code blocks (@{}
).
Combine HTML and C# Logic: Integrate your C# logic seamlessly within your HTML markup to create dynamic content.
Example
@{
// C# logic
string userName = "John"; // This could be retrieved from a database or user input
string greetingMessage = "Hello";
if (DateTime.Now.Hour < 12)
{
greetingMessage = "Good Morning";
}
else if (DateTime.Now.Hour < 17)
{
greetingMessage = "Good Afternoon";
}
else
{
greetingMessage = "Good Evening";
}
}
<!DOCTYPE html>
<html>
<head>
<title>Greeting Page</title>
</head>
<body>
<div>
<h1>Welcome to our website!</h1>
<p>@greetingMessage, @userName!</p>
</div>
</body>
</html>
In this example:
@{}
blocks.userName
and greetingMessage
and assigned them values based on C# logic.@
symbol to output the dynamic content (@greetingMessage
, @userName
) within the HTML markup.When this page is rendered, it will greet the user with "Good Morning", "Good Afternoon", or "Good Evening" depending on the time of day, along with the name "John".
Remember, Razor syntax enables a smooth integration of C# logic and HTML markup, allowing you to create dynamic web content effectively in ASP.NET applications.
Here's a more detailed example:
Let's say you want to display a personalized greeting message on your webpage. You can use Razor syntax to accomplish this.
Create a new Razor page named "Greeting.cshtml":
ASP.NET Razor is a markup syntax used to create dynamic web pages with C# logic embedded within HTML. It allows developers to write server-side code seamlessly within the HTML markup.
Here's a simple example to illustrate:
Let's say you have a simple ASP.NET Razor page named "Greetings.cshtml".
Example
<!DOCTYPE html>
<html>
<head>
<title>Greetings Page</title>
</head>
<body>
<div>
<h1>Welcome to the Greetings Page!</h1>
@{
// C# logic starts here
string name = "John";
string greeting = "Hello";
if (DateTime.Now.Hour < 12)
{
greeting = "Good Morning";
}
else if (DateTime.Now.Hour < 17)
{
greeting = "Good Afternoon";
}
else
{
greeting = "Good Evening";
}
}
<p>@greeting, @name!</p>
</div>
</body>
</html>
In this example:
@{}
syntax to denote C# code blocks.name
and greeting
.@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".
