C# Math Random

Math.Random is a C# function used to generate random numbers. It generates a random number of type double between 0 and 1.

Syntax

double randomNumber = new Random().NextDouble();

Usage

To use Math.Random in your C# code, you need to import the System namespace:

using System;

Once the namespace is imported, you can use Math.Random function to generate random numbers.

double randomNumber = new Random().NextDouble();

In the above example, randomNumber variable will hold a randomly generated double value between 0 and 1.

Seed Value

By default, Random() method uses the current system time as the seed value. This ensures that each time the function is called, a different random number is generated. However, if you want predictable behavior of random function in your program, you can set a particular seed value.

Random randObj = new Random(1234); // Setting seed value to 1234
double randomNumber = randObj.NextDouble();

In the above example, Random() constructor is used to create a new instance of Random class, with a seed value of 1234.

Conclusion

C# Math.Random function is a quick way to generate random numbers in C# language. It is easy to use and provides the flexibility to use custom seed values.
