Hello all,

I have problem with enumeration in c# winforms application.

I have a Enum as foll0ws,

public enum Currency
{
   INR = 0,
   USD = 4545,
   JPY = 2152,
   EUR = 5241

}

I have populated the enum items in a combo box.

I want use the

combobox1.Text

value to get the corresponding numeric value.

For Example :

When I select USD from the combobox, I have to Get the value of 4545 using the enum "Currency".

How can I achieve this...

Please help me.

Thanks in advance.

Use the Enum.Parse.

Enum.Parse (Type, String)
Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object.

Enum.Parse (Type, String, Boolean)
Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object. A parameter specifies whether the operation is case-sensitive.

Solution 2

Try:

enum testEnum
    {
    GBP = 100,
    USD = 200,
    }

...
testEnum te = (testEnum) Enum.Parse(typeof (testEnum), "USD");
...

[edit]
Oh, and in .NET 4.0 and above there is a (much preferable) TryParse:

Enum.TryParse<enumName>(stringNameOfEnumValue, out placeToPutValue);

This works fine for me (I've added a ComboBox called cbCurrencies on the form in design mode):

C#

public partial class Form1 : Form
{
    public enum Currency
    {
        INR = 0,
        USD = 4545,
        JPY = 2152,
        EUR = 5241
    }
    public Form1()
    {
        InitializeComponent();
        // Populate
        cbCurrencies.DataSource = System.Enum.GetValues(typeof(Currency));
    }
    private void cbCurrencies_SelectedIndexChanged(object sender, EventArgs e)
    {
        // Get the selected currency
        Currency cur = (Currency)cbCurrencies.SelectedValue;

        // And get the value in need
        int value = (int)cur;

    }
}
