C# Method Parameters and Arguments

Parameters are variables listed in a method's definition, while arguments are the actual values passed to the method when it is called. Parameters allow methods to accept input and perform operations based on that input.

Key Topics

1. Defining Parameters

Example: Method with Parameters

static void GreetUser(string name)
{
    Console.WriteLine("Hello, " + name + "!");
}

2. Passing Arguments

Example: Calling Method with an Argument

GreetUser("Alice");  // Outputs: Hello, Alice!

3. Multiple Parameters

Example: Method with Multiple Parameters

static void DisplayInfo(string name, int age)
{
    Console.WriteLine($"Name: {name}, Age: {age}");
}

DisplayInfo("Bob", 30);  // Outputs: Name: Bob, Age: 30

Key Takeaways

  • Parameters define what inputs a method can accept.
  • Arguments are the actual values passed to the method.
  • Methods can have multiple parameters to accept various inputs.
  • Proper parameter definition enhances method flexibility and reusability.
