How to generate random value for a variable in C#?

Question

Is there a command that exists in the C# language that would allow my code to assign a random positive value to an int or double variable and maybe a way to set the range of possibilities?
Something like:
int x = (randomValue);
Or a method I can create?
int x = randomValue();
Thanks!

JPressley In C# the Random class is included in the standard System namespace, you dont need any additional library to use it.
It is pretty simple:

using System;

static void Main(string[] args)
{
//Initialize a new object of random class
Random rand = new Random();

// Get a random integer between 0 and 100 and store it in a variable
int x = rand.Next(101);

//Print a random number between 0 and 100
Console.WriteLine(x);

//For floating point you need to use NextDouble() instead and it will generate a random double number between 0 and 1
x = rand.NextDouble();

//if you want a floating point in a greater range you need to multiplicate it, for example to get a random float between 0 and 12 you do
x = rand.NextDouble() * 12;

}

Sure. You can use Random class, take a look :

Right I thought that! But it doesn't show up as a suggestion or compile in my code. Using Visual Studios. The example links only show the System library. Do i need to use additional libraries?
