Switch & Case Statements in C#: Explanation

Dec 23, 2023 | C#

Are you looking for a way to glorify your C# code or simply make it more appetite whetting? Ever heard of switch & case statements in C#? If you’ve been coding in C# for a while, or even if you’re just starting your journey, these two pals are going to be your best friends. Let’s dive deep into the world of C# switch case statements and understand how to use them.

Recognizing the C# Switch Case

With C# becoming an increasingly popular language, it’s imperative to understand the ins and outs of its constructs. One such construct is the C# switch case, your best buddy when dealing with multiple conditions.

C# Switch Case

When coding in C# you’ll soon notice one feature popping up quite often, that’s right it’s our friend the c# switch case. This useful feature can be found in numerous functions, helping to streamline decisions and control them better.

switch (variable) 
{
    case value1:
        // Code to run if variable equals value1
        break;
    case value2:
        // Code to run if variable equals value2
        break;
     default:
        // Code to run if none of the above are matched
        break;
}

The above snippet of code represents a typical switch case in C#. Each case statement uses a different value to evaluate the switch, varying the program behavior based on it.

A Quick Overview of C# Switch Statements

Switch statements are the torque wrench in your coding toolkit, they provide precise control over the multiple execution paths within your application. Let’s zoom in on these powerful tools.

What is a C# Switch Statement?

A switch statement in C#, is a concise way to compare a variable against multiple other values. It contains many case blocks, and a default one too when no match is made.

int choice = 2;
switch (choice)
{
    case 1:
        Console.WriteLine("You chose option 1");
        break;
    case 2:
        Console.WriteLine("You chose option 2");
        break;
    default:
         Console.WriteLine("Invalid choice");
         break;
}

In our code snippet above, the C# switch statement is going to print “You chose option 2”, because our choice variable was set to 2. Cool, right?

C# Select Case

In C#, we don’t just do if-else, we also play with c# select case. It’s another name for our switch case and yes, it is as powerful as its look-alike.

Real-Life Scenarios of C# Select Case

Picture this, you’re building an RPG game where you have different character roles. You could use a series of if-else, but that’s like using a spoon to dig a pit when there’s a shovel handy. Enter, c# select case.

String role = "Warrior";
switch (role)
{
    case "Warrior":
        Console.WriteLine("Your role is a Warrior");
        break;
    case "Mage":
        Console.WriteLine("Your role is a Mage");
        break;
    default:
         Console.WriteLine("Invalid role");
         break;
}

In the depicted scenario, select case made it easy to assign roles to characters based on their user-selected roles. This is a straightforward example, but imagine doing this with a whole bunch of characters!

Switch Case C#

Diving into switch case c# might seem a bit intimidating at first. It’s like diving into a pool filled with code. But trust me, once you get the hang of it, it’ll be second nature to you.

The Syntax of Switch Case C#

Getting the syntax right is like casting a spell, you need to utter the right words to make the magic happen.

switch (expression) 
{
    case constant1:
        // statement(s)
        break;
    case constant2:
        // statement(s)
        break;
    /*...*/
    default:
        // default statements
}

In the above code, the expression is compared with all the constant values in the cases. If it matches with any, the corresponding block(s) of code get executed. And if there’s no match, the default statement is executed.

C# Switch Statement

We’ve all heard that practice makes perfect and with a bit of practice, you too can become a c# switch statement ninja.

C# Switch Statement with Example

With great power, comes great responsibility, or so they say. Well, leveraging the power of C# switch statement certainly feels like wielding mighty power.

char grade = 'A';
switch (grade)
{
    case 'A':
        Console.WriteLine("Excellent!");
        break;
    case 'B':
        Console.WriteLine("Good Job");
        break;
    case 'C':
        Console.WriteLine("Try hard next time");
        break;
    default:
        Console.WriteLine("Invalid grade");
        break;
}

Above, we used a switch statement to handle a grading system. Depending on the grade, it emits different feedback. Gosh! It’s kind of like having a virtual teacher embedded within your code, isn’t it?

C# Switch Type: Adding Flexibility to Decision Making

The ability to use different types with switch statements is one of the great features of C#. It allows us to be flexible with our decision-making process.

Switch Type in C#: Enhancing Your Skills

The C# switch type can give your code an extra touch of sophistication. It’s pretty much like adding a cherry on top of your perfectly baked cake code.

switch (dayOfWeek)
{
    case DayOfWeek.Monday:
    case DayOfWeek.Tuesday:
    case DayOfWeek.Wednesday:
    case DayOfWeek.Thursday:
    case DayOfWeek.Friday:
        Console.WriteLine("It's a weekday");
        break;
    case DayOfWeek.Saturday:
    case DayOfWeek.Sunday:
        Console.WriteLine("It's the weekend!");
        break;
}

In this snippet, you can see how dayOfWeek falls under the enumerated type DayOfWeek, and yet we’re able to run our switch case seamlessly. Isn’t programming in C# a delight?

Multiple Conditions in C#: Complex Decision Handling

Handling complex decisions is like a game of chess, you need to think two steps ahead. Case when multiple conditions in C#, allows us to do just that.

Case When Multiple Conditions in C#: Practical Examples

Possibly, there’s a scenario where you need to run a code based on more than one condition. Yes, you guessed it, this is where case when multiple conditions in C# come riding in on their white horse to save the day!

switch(choice)
{
    case var n when (n >= 0 && n <= 50):
        Console.WriteLine("The number is between 0 and 50");
        break;
    case var n when (n > 50):
        Console.WriteLine("The number is greater than 50");
        break;
    default:
        Console.WriteLine("The number is less or equals 0");
        break;
}

In this example, we’re using range-based conditions in our case statements. This allows us to morph a simple switch case into a powerful tool for complex decision handling. Programming in C# does feel like having a superpower sometimes, doesn’t it?

It’s been a long ride, but I promise it will pay off. Remember, “Great coders aren’t just born. They’re compiled and interpreted!” So keep experimenting with these constructs, and before long, you’ll be swooshing around Switch & Case statements like a pro! You get it, right? If yes, then happy coding! But if not, what’s stopping you? Dive in, start tinkering and master C#! As they say, code is meant to be crafted, not mashed!
