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

Public ReadOnly Property IsArray As Boolean

Property Value

Type: System.Boolean

true if the current type is an array; otherwise, false.



The IsArray property returns false for the Array class. It also returns false if the current instance is a Type object that represents a collection type or an interface designed to work with collections, such as IEnumerable or IEnumerable(Of T).

To check for an array, use code such as:


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.

The following example demonstrates using theIsArray property.

Imports System.Collections
Imports System.Collections.Generic

Module Example
   Public Sub Main()
      Dim types() As Type = { GetType(String), GetType(Integer()),
                              GetType(ArrayList), GetType(Array),
                              GetType(List(Of String)),
                              GetType(IEnumerable(Of Char)) }
      For Each t In types
         Console.WriteLine("{0,-15} IsArray = {1}", t.Name + ":", t.IsArray)
   End Sub
End Module
' The example displays the following output:
'       String:         IsArray = False
'       Int32[]:        IsArray = True
'       ArrayList:      IsArray = False
'       Array:          IsArray = False
'       List`1:         IsArray = False
'       IEnumerable`1:  IsArray = False
