Title: Convert enum values to and from strings in C#

[Convert enum values to and from strings in C#]

The System.Enum class provides several methods that convert enum values to and from strings. Some particularly useful methods include:

GetNameReturns the string name of an enum value.
GetNamesReturns an array of strings holding the names of an enum's values.
GetValuesReturns an array an enum's values.
IsDefinedReturns true if a particular value is defined by an enum.
ParseParses a string and returns the corresponding enum value.

This example uses the following code to demonstrate the GetNames and Parse methods.

// The enumerated type. private enum MealType { Breakfast, Brunch, Lunch, Luncheon = Lunch, Tiffin = Lunch, Tea, Nuncheon = Tea, Dinner, Supper } // Convert values to and from strings. private void Form1_Load(object sender, EventArgs e) { foreach (string value in Enum.GetNames(typeof(MealType))) { // Get the enumeration's value. MealType meal = (MealType)Enum.Parse(typeof(MealType), value); // Display the values. lstStringValues.Items.Add((int)meal + "\t" + value); } }

The code uses Enum.GetNames to get strings representing the MealType values. For each of those strings, it uses Enum.Parse to convert the string into a MealType value. It then displays the value as an integer and in its string form.
