C# Random Sample

Description

Random Sample returns a random floating-point number between 0.0 and 1.0.

Syntax

Random.Sample has the following syntax.


protected virtual double Sample()

Returns

Random.Sample method returns A double-precision floating point number greater than or equal to 0.0, and less than 1.0.

Example

The following example shows how to use Sample method.


//from  w w  w  . j  a  v  a2s.c o m
using System;

public class RandomProportional : Random
{
    protected override double Sample( )
    {
        return Math.Sqrt( base.Sample( ) );
    }

    public override int Next()
    {
       return (int) (Sample() * int.MaxValue);
    }   
}

public class RandomSampleDemo  
{
    static void Main( )
    {  
        RandomProportional randObj = new RandomProportional( );

        for( int j = 0; j < 10; j++ ){
           Console.WriteLine(randObj.NextDouble( ) );
        }

        for( int j = 0; j < 10; j++ ){
           Console.Write( "{0,12}", randObj.Next( ) );
        }
    }
}

The code above generates the following result.
