Voraussetzungen
Bevor Sie beginnen, stellen Sie sicher, dass Sie Folgendes haben:
- Visual Studio or .NET CLI installed
- .NET Framework or .NET Core SDK
- Basic C# programming knowledge
You can simply use the Enum.Parse() function as shown below:
using System;
enum Colors { None=0, Red = 1, Green = 2, Blue = 4 };
public class Example
{
public static void Main()
{
string[] colorStrings = { "0", "2", "8", "blue", "Blue", "Yellow", "Red, Green" };
foreach (string colorString in colorStrings)
{
try {
Colors colorValue = (Colors) Enum.Parse(typeof(Colors), colorString);
if (Enum.IsDefined(typeof(Colors), colorValue) | colorValue.ToString().Contains(","))
Console.WriteLine("Converted '{0}' to {1}.", colorString, colorValue.ToString());
else
Console.WriteLine("{0} is not an underlying value of the Colors enumeration.", colorString);
}
catch (ArgumentException) {
Console.WriteLine("'{0}' is not a member of the Colors enumeration.", colorString);
}
}
}
}
// The example displays the following output:
// Converted '0' to None.
// Converted '2' to Green.
// 8 is not an underlying value of the Colors enumeration.
// 'blue' is not a member of the Colors enumeration.
// Converted 'Blue' to Blue.
// 'Yellow' is not a member of the Colors enumeration.
// Converted 'Red, Green' to Red, Green.More details can be found at: (http://msdn.microsoft.com/en-us/library/system.enum.parse.aspx)
