C#/.NET - get random element from enum
5 points
In this article we are going to have a look at how to get random element from enum.
Quick solution:
xxxxxxxxxx1
Random random = new Random();2
3
Type type = typeof(MyEnum);4
Array values = type.GetEnumValues();5
int index = random.Next(values.Length);6
7
MyEnum value = (MyEnum)values.GetValue(index);In this section we get random enum with typeof operator.
To get value do following steps:
- get
enumtype object, - get array of available values,
- get random value from the array with Random object.
Check practical example below:
xxxxxxxxxx1
using System;2
3
namespace Test4
{5
public enum CustomColor6
{7
Green,8
Blue,9
Red,10
Yellow11
}12
13
class Program14
{15
public static void Main(string[] args)16
{17
Random random = new Random();18
Type type = typeof(CustomColor);19
20
Array values = type.GetEnumValues();21
//Array values = Enum.GetValues(type);22
23
for(int i = 0; i < 10; ++i)24
{ 25
int index = random.Next(values.Length);26
CustomColor value = (CustomColor)values.GetValue(index);27
28
Console.WriteLine(value);29
}30
}31
}32
}Output:
