C# params
In C#, "params" is a keyword used in method parameter to indicate that a method can accept a different number of parameters of the same type. This feature is often used when you want to create methods that can accept an undecided number of parameters.
Params in C# with Example One
using System;
class CSharpTutorial
{
static void Main(string[] args)
{
// Creating Object
CSharpTutorial csharp = new CSharpTutorial();
// You can pass multiple integers as arguments
csharp.ExampleMethod(1, 2, 3);
// You can pass a single integer
csharp.ExampleMethod(4);
// You can even call it with no arguments
csharp.ExampleMethod();
}
private void ExampleMethod(params int[] numbers)
{
foreach (int num in numbers)
{
Console.WriteLine(num);
}
}
}
using System;
class CSharpTutorial
{
static void Main(string[] args)
{
// Creating Object
CSharpTutorial csharp = new CSharpTutorial();
// You can pass multiple integers as arguments
csharp.ExampleMethod(1, 2, 3);
// You can pass a single integer
csharp.ExampleMethod(4);
// You can even call it with no arguments
csharp.ExampleMethod();
}
private void ExampleMethod(params int[] numbers)
{
foreach (int num in numbers)
{
Console.WriteLine(num);
}
}
}
Output
1
2
3
4
Params in C# with Example Two
using System;
class CSharpTutorial
{
static void Main(string[] args)
{
// Creating Object
CSharpTutorial csharp = new CSharpTutorial();
csharp.AnotherExampleMethod("Hello", 1, "World", true);
}
private void AnotherExampleMethod(string message, params object[] values)
{
Console.WriteLine(message);
foreach (object val in values)
{
Console.WriteLine(val);
}
}
}
using System;
class CSharpTutorial
{
static void Main(string[] args)
{
// Creating Object
CSharpTutorial csharp = new CSharpTutorial();
csharp.AnotherExampleMethod("Hello", 1, "World", true);
}
private void AnotherExampleMethod(string message, params object[] values)
{
Console.WriteLine(message);
foreach (object val in values)
{
Console.WriteLine(val);
}
}
}
Output
Hello
1
World
true
Summary
The "params" keyword provides flexibility when working with methods that need to accept a unknown variable number of arguments, making your code more versatile.
