Enum.GetValues 方法

检索指定枚举中常数值的数组。

**命名空间:**System
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
<ComVisibleAttribute(True)> _
Public Shared Function GetValues ( _
    enumType As Type _
) As Array
用法
Dim enumType As Type
Dim returnValue As Array

returnValue = Enum.GetValues(enumType)

[ComVisibleAttribute(true)] 
public static Array GetValues (
    Type enumType
)

[ComVisibleAttribute(true)] 
public:
static Array^ GetValues (
    Type^ enumType
)

/** @attribute ComVisibleAttribute(true) */ 
public static Array GetValues (
    Type enumType
)

ComVisibleAttribute(true) 
public static function GetValues (
    enumType : Type
) : Array

参数

• enumType
  枚举类型。

返回值

enumType 的常数值的 Array。该数组的元素按枚举常数的值排序。

异常

异常类型	条件
ArgumentNullException	enumType 为 空引用（在 Visual Basic 中为 Nothing）。
ArgumentException	enumType 不是 Enum。

示例

下面的代码示例说明如何使用 GetValues：

Imports System

Public Class GetValuesTest
    
    Enum Colors
        Red
        Green
        Blue
        Yellow
    End Enum 'Colors
    
    Enum Styles
        Plaid = 0
        Striped = 23
        Tartan = 65
        Corduroy = 78
    End Enum 'Styles
    
    Public Shared Sub Main()
        
        Console.WriteLine("The values of the Colors Enum are:")
        Dim i As Integer
        For Each i In  [Enum].GetValues(GetType(Colors))
            Console.WriteLine(i)
        Next i

        Console.WriteLine()
        
        Console.WriteLine("The values of the Styles Enum are:")
        For Each i In  [Enum].GetValues(GetType(Styles))
            Console.WriteLine(i)
        Next i
    End Sub 'Main
End Class 'GetValuesTest

using System;

        Console.WriteLine();

        Console.WriteLine("The values of the Styles Enum are:");
        foreach(int i in Enum.GetValues(typeof(Styles)))
            Console.WriteLine(i);
    }
}
