.NET Framework Class Library
Type..::.IsArray Property

Gets a value indicating whether the Type is an array.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
Public ReadOnly Property IsArray As Boolean
public bool IsArray { get; }
public:
virtual property bool IsArray {
	bool get () sealed;
}
abstract IsArray : bool
override IsArray : bool

Property Value

Type: System..::.Boolean
true if the Type is an array; otherwise, false.

Implements

_Type..::.IsArray
Remarks

The IsArray property returns false for the Array class.

To check for an array, use code such as typeof(Array).IsAssignableFrom(type).

If the current Type represents a generic type, or a type parameter in the definition of a generic type or generic method, this property always returns false.

This property is read-only.

Examples

The following example demonstrates using the IsArray property.


Imports System

Class TestIsArray
    Public Shared Sub Main()
        Dim array As Integer() =  {1, 2, 3, 4}
        Dim at As Type = GetType(Array)
        Dim t As Type = array.GetType()
        Console.WriteLine("The type is {0}. Is this type an array? {1}", at, at.IsArray)
        Console.WriteLine("The type is {0}. Is this type an array? {1}", t, t.IsArray)
    End Sub 'Main
End Class 'TestType


using System;
class TestIsArray 
{
    public static void Main() 
    {
    int [] array = {1,2,3,4};
    Type at = typeof(Array);
    Type t = array.GetType();
    Console.WriteLine("The type is {0}. Is this type an array? {1}", at, at.IsArray);
    Console.WriteLine("The type is {0}. Is this type an array? {1}", t, t.IsArray);
    }
}


using namespace System;
int main()
{
   array<Int32>^array = {1,2,3,4};
   Type^ at = Array::typeid;
   Type^ t = array->GetType();
   Console::WriteLine( "The type is {0}. Is this type an array? {1}", at, at->IsArray.ToString() );
   Console::WriteLine( "The type is {0}. Is this type an array? {1}", t, t->IsArray.ToString() );
}

This code produces the following output:

Type is System.Array. IsArray? False
Type is System.Int32[]. IsArray? True
