using namespace System;
int main()
{
   
   // Creates and initializes a one-dimensional array.
   array<String^>^myArr1 = gcnew array<String^>(5);
   
   // Sets the element at index 3.
   myArr1->SetValue( "three", 3 );
   Console::WriteLine( "[3]:   {0}", myArr1->GetValue( 3 ) );
   
   // Creates and initializes a two-dimensional array.
   array<String^, 2>^myArr2 = gcnew array<String^,2>(5,5);
   
   // Sets the element at index 1,3.
   myArr2->SetValue( "one-three", 1, 3 );
   Console::WriteLine( "[1,3]:   {0}", myArr2->GetValue( 1, 3 ) );

GetValue(Int32)

Source:: Array.cs

Source:: Array.cs

Source:: Array.cs

Gets the value at the specified position in the one-dimensional Array. The index is specified as a 32-bit integer.

public:
 System::Object ^ GetValue(int index);

public object GetValue (int index);

public object? GetValue (int index);

member this.GetValue : int -> obj

Public Function GetValue (index As Integer) As Object

Parameters

index: Int32

A 32-bit integer that represents the position of the Array element to get.

Returns

Object

The value at the specified position in the one-dimensional Array.

Exceptions

ArgumentException

The current Array does not have exactly one dimension.

IndexOutOfRangeException

index is outside the range of valid indexes for the current Array.

Remarks

The GetLowerBound and GetUpperBound methods can determine whether the value of index is out of bounds.

This method is an O(1) operation.

Applies to

GetValue(Int32[])

Source:: Array.cs

Source:: Array.cs

Source:: Array.cs

Gets the value at the specified position in the multidimensional Array. The indexes are specified as an array of 32-bit integers.
