The following code example demonstrates how to set and get a specific value in a one-dimensional or multidimensional array.

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 ) ); // Creates and initializes a three-dimensional array. array<String^, 3>^myArr3 = gcnew array<String^,3>(5,5,5); // Sets the element at index 1,2,3. myArr3->SetValue( "one-two-three", 1, 2, 3 ); Console::WriteLine( "[1,2,3]: {0}", myArr3->GetValue( 1, 2, 3 ) ); // Creates and initializes a seven-dimensional array. array<String^, 7>^myArr7 = gcnew array<String^,7>(5,5,5,5,5,5,5); // Sets the element at index 1,2,3,0,1,2,3. array<Int32>^myIndices = {1,2,3,0,1,2,3}; myArr7->SetValue( "one-two-three-zero-one-two-three", myIndices ); Console::WriteLine( "[1,2,3,0,1,2,3]: {0}", myArr7->GetValue( myIndices ) ); This code produces the following output.

public object GetValue (int index);
public object? GetValue (int index);
member this.GetValue : int -> obj
Public Function GetValue (index As Integer) As Object

Parameters

Remarks

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

This method is an O(1) operation.

public:
 System::Object ^ GetValue(... cli::array <int> ^ indices);
public object GetValue (params int[] indices);
public object? GetValue (params int[] indices);
member this.GetValue : int[] -> obj
Public Function GetValue (ParamArray indices As Integer()) As Object

Parameters

A one-dimensional array of 32-bit integers that represent the indexes specifying the position of the Array element to get.

Returns

Remarks

The number of elements in indices must equal the number of dimensions in the Array . All elements in the indices array must collectively specify the position of the desired element in the multidimensional Array .

The GetLowerBound and GetUpperBound methods can determine whether any of the indexes is out of bounds.

This method is an O(1) operation.
