Converting Numeric Value to Words Format in WPF

In this blog I want to share the code that I have written for converting numeric value to its words format.

This is my first blog in C# corner. In this blog I want to share the code that I have written for converting numeric value to its words format. It is very simple prototype and can be extended to be used as full fledged application or user control.

In this example I have a list of numbers which is to be populated in combo box. At the time of displaying numbers in combo box, they should be shown in words. For ex., 1 -> one, 2 -> two

For this purpose I have created Data Converter inherited from IValueConveter interface provided by WPF library.

To create a value converter, we need to take four steps:

1. Create a class that implements IValueConverter.
    
2. Add the ValueConversion attribute to the class declaration, and specify the destination and target data types.
    
3. Implement a Convert() method that changes data from its original format to its display format.
    
4. Implement a ConvertBack() method that does the reverse and changes a value from display format to its native format.
   
   
    

   public class DataConverter : IValueConverter

   public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

   public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
   
   In Convert method I have written the logic to convert numeric value into word and return the string.
   
   Coming to UI side, window contains just a combo box to be populated with list using data context (binding). The list contains all the numbers hence we need to put converter to convert numeric values to words.
    

   <ComboBox

    ItemsSource="{Binding list,  

    Converter={StaticResource DataConverter}}">

Finally the application looks like
