How to get the value of a Enumeration Item?

petre ricardo

Hi,
I have the following enumeration:

 

Enum E1
{   LOW = 'L',

   MEDIUM = 'M',

   HIGH = 'H'

}

I have loaded those values to a combo box, but how do i display the value of "MEDIUM" (I.E. M), when i select "MEDIUM" from the combo box?
TY in Advance

Hi ,

You can use Dictionary as same as Enum

look at Below Code That Does the same What you want With Dictionary

        Dictionary<string, char> e1;
        private void Form1_Load(object sender, EventArgs e)
        {
            e1 = new Dictionary<string, char>();
            e1.Add("LOW", 'L');
            e1.Add("MEDIUM", 'M');
            e1.Add("HIGH", 'H');

            foreach (string str in e1.Keys)
            {
                comboBox1.Items.Add(str);
            }

        }
        private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
           foreach(KeyValuePair<string,char> k in e1)
           {
               if (k.Key == comboBox1.SelectedItem.ToString())
               {
                   MessageBox.Show(k.Value.ToString());
               }
           }
        }

(E1)Enum.Parse(typeof(Colors),cmbPriority.SelectedValue.ToString()); this is how you convert string to Enum again

When i do the following:
string p = ((E1)cmbPriority.SelectedValue).ToString(); MessageBox.Show(p);
it throws an run time error: Object reference not set to an instance of an Object

well my friend, the Enum is an Enumerabel Type meaning you can do the following (char)E1.Medium in order to get the char value of the Enum

I.E.:

  E1 e1 = E1.MEDIUM;
  char c = (char)e1;
  Console.WriteLine(string.Format("You selection is : \'{0}\'",c));
