Exploring Conditional Filtering in LINQ: Applying If Statements for Dynamic Data Filtering

 In LINQ (Language Integrated Query), the primary way to conditionally filter data is by using the Where clause. This allows you to specify a predicate that determines whether an element should be included in the result or not. The predicate can include if statements to apply conditional logic.

Here's an example of applying an if statement within a LINQ query using the Where clause:

var numbers = new List<int> { 1, 2, 3, 4, 5, 6 };

var filteredNumbers = numbers.Where(num => {
    if (num % 2 == 0) // Check if the number is even
    {
        // Apply additional condition for even numbers
        return num > 2;
    }
    else
    {
        // Apply different condition for odd numbers
        return num < 5;
    }
});

foreach (var num in filteredNumbers)
{
    Console.WriteLine(num);
}

In this example, we have a list of numbers, and we want to filter them based on different conditions depending on whether they are even or odd. If the number is even, we check if it's greater than 2. If the number is odd, we check if it's less than 5. The Where clause includes an inline lambda expression that applies the if statement logic.

The resulting output will be:

3
4
5
6

As you can see, the if statement is used to conditionally apply filters within the LINQ query. You can adapt this approach to your specific requirements, adjusting the conditions and logic inside the if statements as needed.
