Type.GetElementType Method

public:
 abstract Type ^ GetElementType();

public abstract Type GetElementType();

public abstract Type? GetElementType();

abstract member GetElementType : unit -> Type

Public MustOverride Function GetElementType () As Type

The Type of the object encompassed or referred to by the current array, pointer, or reference type, or null if the current Type is not an array or a pointer, or is not passed by reference, or represents a generic type or a type parameter in the definition of a generic type or generic method.

The following example demonstrates using the GetElementType method.

using namespace System;
public ref class TestGetElementType{};

int main()
{
   array<Int32>^array = {1,2,3};
   Type^ t = array->GetType();
   Type^ t2 = t->GetElementType();
   Console::WriteLine( "The element type of {0} is {1}.", array, t2 );
   TestGetElementType^ newMe = gcnew TestGetElementType;
   t = newMe->GetType();
   t2 = t->GetElementType();
   Console::WriteLine( "The element type of {0} is {1}.", newMe, t2 == nullptr ? "null" : t2->ToString() );
}

/* This code produces the following output:

The element type of System.Int32[] is System.Int32.
The element type of TestGetElementType is null.
 */

using System;
class TestGetElementType
{
    public static void Main()
    {
        int[] array = {1,2,3};
        Type t = array.GetType();
        Type t2 = t.GetElementType();
        Console.WriteLine("The element type of {0} is {1}.",array, t2.ToString());
        TestGetElementType newMe = new TestGetElementType();
        t = newMe.GetType();
        t2 = t.GetElementType();
        Console.WriteLine("The element type of {0} is {1}.", newMe, t2==null? "null" : t2.ToString());
    }
}

/* This code produces the following output:

The element type of System.Int32[] is System.Int32.
The element type of TestGetElementType is null.
 */

type TestGetElementType() = class end
do
    let array = [| 1; 2; 3 |]
    let t = array.GetType()
    let t2 = t.GetElementType()
    printfn $"The element type of {array} is {t2}."
    
    let newMe = TestGetElementType()
    let t = newMe.GetType()
    let t2 = t.GetElementType()
    printfn $"""The element type of {newMe} is {if t2 = null then "null" else string t2}."""

End Class

' This code produces the following output:
'
'The element type of System.Int32[] is System.Int32.
'The element type of TestGetElementType is null.

This method returns null for the Array class.
