Array::GetValue Method (Int32)

.NET Framework (current version)
 

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

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

C#
C++
F#
VB
Copy 
public:
Object^ GetValue(
	int index
)

Parameters

index
Type: System::Int32

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

Return Value

Type: System::Object^

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

Exception Condition
ArgumentException

The current Array does not have exactly one dimension.

IndexOutOfRangeException

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

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

This method is an O(1) operation.

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

C#
C++
VB
Copy 
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.

[3]:   three
[1,3]:   one-three
[1,2,3]:   one-two-three
[1,2,3,0,1,2,3]:   one-two-three-zero-one-two-three
