If you want to replace multiple if-else statements in code, which statement will you use?

by

In Visual basic, we can use Select-Case statement to replace multiple If-Else statement. In C#, we should use Switch-Case statement to replace multiple If-Else statement.

In the context of .NET, if you want to replace multiple if-else statements in code, you can use a switch statement.

A switch statement provides a cleaner and more organized way to handle multiple conditions compared to numerous if-else statements. It evaluates an expression and then executes code blocks based on the value of that expression. Here’s a basic example:

csharp
int number = 3;

switch (number)
{
case 1:
Console.WriteLine("One");
break;
case 2:
Console.WriteLine("Two");
break;
case 3:
Console.WriteLine("Three");
break;
default:
Console.WriteLine("Number not found");
break;
}

In this example, if number is 3, it will print “Three”. If it’s not 1, 2, or 3, it will print “Number not found”.

Switch statements are particularly useful when you have a discrete set of possible values that you need to compare against. However, it’s important to note that switch statements are not always the best choice, especially when dealing with more complex conditions or when the number of cases is very large. In such cases, other control structures or design patterns might be more appropriate.
