# Solved: random number between 1 and 100

Random numbers are a key concept in programming that find utility in a wide range of applications. They play a significant role in different areas such as cryptography, simulations, testing, and games. Especially in C#, generating a random integer between 1 and 100 has an abundance of practical implications. In this article, we will explore how to accomplish this task in C#, further diving into the libraries, functionalities, and step-by-step explanation of the code.

## The C# Random Class

The C# Random class, a built-in class available in the System namespace, provides functionality for generating random numbers. In the Random class, several methods are available, but the two primarily used are Next() and NextBytes(). For generating a random integer in the range of 1 to 100, we use the Next() method.

Random random = new Random();
int randomNumber = random.Next(1, 101);

As you can see in the example, “Random” is initiated and subsequently used to generate the random number. The Next() method is called with two parameters: the minimum and the upper (exclusive) limit. This Two-parameter version of the Next function is going to generate a random number that is greater or equal to the first parameter, and less than the second parameter.

## A Step-by-Step Breakdown of the Code

• First, an instance of the Random class is created with the line ‘Random random = new Random();’. This object will be used to generate our random number.
• Second, we call the Next() function on our Random object with the parameters 1 and 101. As these are inclusive and exclusive limits respectively, the generated number will be in the range of 1-100.

Executing the “random.Next(1, 101)” line of code will produce a random integer between 1 and 100.

## An Insightful Dive into The System Namespace

In C#, the System namespace contains fundamental classes and base classes that define commonly-used value and reference data types, events and event handlers, interfaces, attributes, and processing exceptions.

The System namespace is the motherlode of numerous integral .NET classes. For instance, the Random class, which we’ve been discussing, is nestled right into it. Many other classes such as DateTime, Math, String, and more are also part of the System namespace, being foundational components in most C# programs.

Finally, as we’ve come full circle in our understanding of generating random numbers in C#, it’s clear that with the correct knowledge of the associated classes and methods, the task is quite straightforward. It’s crucial to remember that C# and its libraries provide powerful tools such as the Random class to aid programmers in achieving desired functionalities efficiently.
