C# Enumerations in random

Jonathan Crispe

I have enum: "Ten, Jack, Queen, King, Ace"

how can i make it a random,

i mean, if a press a button
it will display 5 cards randomly...

like in the picture below

my code:
public enum m_Cards { Ten, Jack, Queen, King, Ace };
private void button1_Click(object sender, EventArgs e)
{
m_Cards[] cHand = new m_Cards[5];
Random random = new Random();
}

i tried adding for loop but says its missing a cast, so i delete it...
thank you for the help...

Try this:

public partial class Form1 : Form
{
public enum m_Cards { Ten, Jack, Queen, King, Ace };

private Random random;

private Label[] cardsDrawn;
private Label[] results;

public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
cardsDrawn = new Label[] { label1, label2, label3, label4, label5 };
results = new Label[]{label6, label7};
random = new Random();
}

private void button1_Click(object sender, EventArgs e)
{
m_Cards[] cHand = new m_Cards[5];
for (int i = 0; i < 5; i++)
{
cHand[i] = (m_Cards)random.Next(5); // 0 to 4
cardsDrawn[i].Text = cHand[i].ToString();
}
AnalyzeHand(cHand);
}

private void AnalyzeHand(m_Cards[] cHand)
{
label6.Text = "";
label7.Text = "";
int[] cardCounts = new int[5]; // all zero initially
foreach(m_Cards card in cHand) cardCounts[(int)card]++;
int nextResult = 0;

for (int i = 0; i < 5; i++)
{
if (cardCounts[i] == 2)
{
results[nextResult].Text = "A pair of " + ((m_Cards)i).ToString() + "s";
nextResult++;
if (nextResult > 1) nextResult = 0;
}
else if (cardCounts[i] == 3)
{
results[nextResult].Text = "Three of a kind of " + ((m_Cards)i).ToString() + "s";
nextResult++;
if (nextResult > 1) nextResult = 0;
}
else if (cardCounts[i] == 4)
{
results[nextResult].Text = "Four of a kind of " + ((m_Cards)i).ToString() + "s";
return; // can't be any further results
}
}

if (label6.Text == "") // no results printed yet
{
label6.Text = "A straight";
}
}
}

Hi Jonathan,

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public enum m_Cards
{
Ten, Jack, Queen, King, Ace
}

private void button1_Click(object sender, EventArgs e)
{
Random rand = new Random();
m_Cards a= (m_Cards)(rand.Next()% 5);
textBox1.Text = a.ToString();
//MessageBox.Show(a.ToString());
}
}
}

Thanks
