public class FontNamesConverter : TypeConverter

Use the ConvertFrom method of this class to convert a single string containing a list of font names to an array of strings containing the individual names. Each font name in the string must be separated by a comma. For example, the string "arial, times new roman, verdana", converts to an array that contains the strings "arial", "times new roman", and "verdana". Notice the commas are removed along with any white space at the beginning or end of the font name. White space in the middle of a font name is not removed.

The ConvertTo method performs the reverse operation. It converts an array of strings containing the individual font names to a single string containing a list of the names. For example, an array that contains the strings "arial", "times new roman", and "verdana" converts to the string "arial,times new roman,verdana". Notice that commas are automatically inserted between the font names without any white space.

Call the CanConvertFrom method to verify that the conversion can be made before calling the ConvertFrom method.

The following code example demonstrates how to use the FontNamesConverter class to convert a string with a list of font names to an array of strings containing the individual names. The array of strings is then converted back to a single string and displayed.
