Array.GetValue() Method in C# with Examples | Set – 2
Array.GetValue() Method in C# is used to gets the value of the specified element in the current Array. There are total 8 methods in the overload list of this method which are as follows:
- Array.GetValue(Int32, Int32)
- Array.GetValue(Int64, Int64)
- Array.GetValue(Int32)
- Array.GetValue(Int64)
- Array.GetValue(Int32, Int32, Int32)
- Array.GetValue(Int64, Int64, Int64)
- GetValue(Int32[])
- GetValue(Int64[])
Here, we are explaining Array.GetValue(Int32) and Array.GetValue(Int64) method.
GetValue(Int32) method is used to get the value at the specified position in the one-dimensional Array. The index is specified as a 32-bit integer.
Syntax:
public object GetValue (int index);
Here, the index is the 32-bit integer that represents the position of the Array element to get.
Returns: This method returns the value at the specified position in the one-dimensional Array of object type.
Exceptions:
- ArgumentException: If the current Array does not have exactly one dimension.
- IndexOutOfRangeException: If the index is outside the range of valid indexes for the current Array.
GetValue(Int64) method is used to get the value at the specified position in the one-dimensional Array. The index is specified as a 64-bit integer.
Syntax:
public object GetValue (long index);
Here, the index is the 64-bit integer that represents the position of the Array element to get.
Returns: This method returns the value at the specified position in the one-dimensional Array of object type.
Exceptions:
- ArgumentException: If the current Array does not have exactly one dimension.
- IndexOutOfRangeException: If the index is outside the range of valid indexes for the current Array.
Example 1:
using System;
public class GFG {
public static void Main()
{
char [] arr = new char []{ 'A' , 'B' , 'C' , 'D' };
Console.WriteLine( "element at index 3 is : " + arr.GetValue(3));
Console.WriteLine( "element at index 1 is : " + arr.GetValue(1));
Console.WriteLine( "element at index 2 is : " + arr.GetValue(2));
Console.WriteLine( "element at index 0 is : " + arr.GetValue(0));
}
}
|
Output:
element at index 3 is : D
element at index 1 is : B
element at index 2 is : C
element at index 0 is : A
Example 2:
using System;
public class GFG {
public static void Main()
{
string [] arr = new string [5];
arr.SetValue( "C++" , 0 );
arr.SetValue( "Java" , 1 );
arr.SetValue( "C#" , 2 );
arr.SetValue( "Perl" , 3 );
arr.SetValue( "Python" , 4 );
Console.WriteLine( "element at index 3 is : " + arr.GetValue(3));
Console.WriteLine( "element at index 1 is : " + arr.GetValue(1));
Console.WriteLine( "element at index 2 is : " + arr.GetValue(2));
Console.WriteLine( "element at index 0 is : " + arr.GetValue(0));
Console.WriteLine( "element at index 0 is : " + arr.GetValue(4));
}
}

Output:
element at index 3 is : Perl
element at index 1 is : Java
element at index 2 is : C#
element at index 0 is : C++
element at index 0 is : Python
Note: For online compiler it’s not possible to use 32-bit or 64-bit integer. Use offline compiler for 32 or 64-bit integer.
