C# Params Array2 min read

Sometimes a situation may arise where you do not know how many parameters you want to pass to a method or you may want the method to accept n number of parameters at runtime. In such times params type array can solve the problem. param is a keyword in C# that creates an array at runtime that receives and holds as many numbers of parameters as you want.

The length of params will be zero if no arguments will be passed. Although only one params keyword is allowed and no other parameters are allowed after the method declaration.

Let us see it in a program.


C# Program to demonstrate the params Array

Let us create two classes, one class will contain the method and another class where the main class will be present. The method will be accessed by creating an instance of the class in the main function.

Output:


Example: C# Program to pass different data-types and print them

Let us see another example where we pass different data-type inputs and print them all with param. We will use object type params that allow us to enter as many numbers of inputs as we want of different data types.

Output:
