对于enum类型
：
使用foreach遍历enum类型的元素并填充combox
| 代码如下 | 复制代码 |
|
foreach ( HatchStyle hs1 in Enum.GetValues(typeof(HatchStyle))) { comboBox1.Items.Add(hs1.ToString()); } |
|
例子
| 代码如下 | 复制代码 |
|
public enum BeepType { SimpleBeep = -1, IconAsterisk = 0x00000040, IconExclamation = 0x00000030, IconHand = 0x00000010, IconQuestion = 0x00000020, Ok = 0x00000000, } string[] x = (string[])Enum.GetNames(typeof(Win32Api.BeepType)); int[] y = (int[])Enum.GetValues(typeof(Win32Api.BeepType)); for (int i = 0; i < 100; i++) { MessageBox.Show(i.ToString()); Win32Api.MessageBeep((Win32Api.BeepType)i); } |
|
枚举可用来存储字符串与数字的值对，相当于一个对照表
常用方法：GetName(),GetValue(),Parse()
| 代码如下 | 复制代码 |
|
using System; public class EnumTest { enum Days { Saturday, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday }; enum BoilingPoints { Celcius = 100, Fahrenheit = 212 }; [FlagsAttribute] enum Colors { Red = 1, Green = 2, Blue = 4, Yellow = 8 }; public static void Main() { Type weekdays = typeof(Days); Type boiling = typeof(BoilingPoints); Console.WriteLine("The days of the week, and their corresponding values in the Days Enum are:"); foreach ( string s in Enum.GetNames(weekdays) ) Console.WriteLine( "{0,-11}= {1}", s, Enum.Format( weekdays, Enum.Parse(weekdays, s), "d")); Console.WriteLine(); Console.WriteLine("Enums can also be created which have values that represent some meaningful amount."); Console.WriteLine("The BoilingPoints Enum defines the following items, and corresponding values:"); foreach ( string s in Enum.GetNames(boiling) ) Console.WriteLine( "{0,-11}= {1}", s, Enum.Format(boiling, Enum.Parse(boiling, s), "d")); Colors myColors = Colors.Red | Colors.Blue | Colors.Yellow; Console.WriteLine(); Console.WriteLine("myColors holds a combination of colors. Namely: {0}", myColors); } } |
