Question

I’m using a enum with countries in a comboBox. All enums are in a class called Countries. Some of them has underscores like United_States_of_America. I need to remove those underscores before it shows in the comboBox?

My thought was to use Replace("_", " "), simple if it was a common string, but not so simple with a combobox! Therefore I would preciate some help to solve this? Thanks!

private void InitializeGUI()
{
    // Fill comboBox with countries
    cmbCountries.Items.AddRange(Enum.GetNames(typeof(Countries))); 
}

Use the power of Linq 🙂

private void InitializeGUI() 
{ 
    // Fill comboBox with countries 
    cmbCountries.Items.AddRange(Enum.GetNames(typeof(Countries))
                                    .Select(c => c.Replace("_", " "));  
} 

Or using a foreach:

private void InitializeGUI() 
{ 
    // Fill comboBox with countries 
    string[] countryNames = Enum.GetNames(typeof(Countries));
    foreach (string countryName in countryNames)
    {
        cmbCountries.Items.Add(countryName.Replace("_", " "));
    }
}
