public:
 static void Reverse(Array ^ array, int index, int length);
public static void Reverse (Array array, int index, int length);
static member Reverse : Array * int * int -> unit

参数

array
Array

要反转的一维 ArrayThe one-dimensional Array to reverse.

index
Int32

要反转的部分的起始索引。The starting index of the section to reverse.

length
Int32

要反转的部分中的元素数。The number of elements in the section to reverse.

异常

arraynullarray is null.

array 是多维的。array is multidimensional.

index 小于 array 的下限。index is less than the lower bound of array.

- 或 --or- length 小于零。length is less than zero.

indexlength 未在 array 中指定有效范围。index and length do not specify a valid range in array.

示例

下面的代码示例演示如何对 Array中的一系列元素中的值进行反向排序。The following code example shows how to reverse the sort of the values in a range of elements in an Array.

using namespace System;
void PrintIndexAndValues( Array^ myArray );
void main()
{
   // Creates and initializes a new Array instance.
   Array^ myArray = Array::CreateInstance( String::typeid, 9 );
   myArray->SetValue( "The", 0 );
   myArray->SetValue( "QUICK", 1 );
   myArray->SetValue( "BROWN", 2 );
   myArray->SetValue( "FOX", 3 );
   myArray->SetValue( "jumps", 4 );
   myArray->SetValue( "over", 5 );
   myArray->SetValue( "the", 6 );
   myArray->SetValue( "lazy", 7 );
   myArray->SetValue( "dog", 8 );

   // Displays the values of the Array.
   Console::WriteLine(  "The Array instance initially contains the following values:" );
   PrintIndexAndValues( myArray );

   // Reverses the sort of the values of the Array.
   Array::Reverse( myArray, 1, 3 );

   // Displays the values of the Array.
   Console::WriteLine(  "After reversing:" );
   PrintIndexAndValues( myArray );
}

void PrintIndexAndValues( Array^ myArray )
{
   for ( int i = myArray->GetLowerBound( 0 ); i <= myArray->GetUpperBound( 0 ); i++ )
      Console::WriteLine(  "\t[{0}]:\t{1}", i, myArray->GetValue( i ) );
}

Reverse<T>(T[])

反转一维泛型数组中元素的顺序。Reverses the sequence of the elements in the one-dimensional generic array.

public:
generic <typename T>
 static void Reverse(cli::array <T> ^ array);
public static void Reverse<T> (T[] array);
static member Reverse : 'T[] -> unit
Public Shared Sub Reverse(Of T) (array As T())

类型参数

T

array 中的元素的类型。The type of the elements in array.

参数

array
T[]

要反转的元素的一维数组。The one-dimensional array of elements to reverse.

异常

arraynullarray is null.

array 是多维的。array is multidimensional.

Reverse<T>(T[], Int32, Int32)

反转一维泛型数组中元素子集的顺序。Reverses the sequence of a subset of the elements in the one-dimensional generic array.

public:
generic <typename T>
 static void Reverse(cli::array <T> ^ array, int index, int length);
public static void Reverse<T> (T[] array, int index, int length);
static member Reverse : 'T[] * int * int -> unit
Public Shared Sub Reverse(Of T) (array As T(), index As Integer, length As Integer)

类型参数

T

array 中的元素的类型。The type of the elements in array.

参数

array
T[]
