Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets a value that indicates whether the type is an array.
public:
virtual property bool IsArray { bool get(); };
public:
property bool IsArray { bool get(); };
public virtual bool IsArray { get; }
public bool IsArray { get; }
member this.IsArray : bool
Public Overridable ReadOnly Property IsArray As Boolean
Public ReadOnly Property IsArray As Boolean
Property Value
true
if the current type is an array; otherwise, false
.

Examples
The following example demonstrates using the IsArray property.
using System;
using System.Collections;
using System.Collections.Generic;
public class Example
{
public static void Main()
{
Type[] types = { typeof(String), typeof(int[]),
typeof(ArrayList), typeof(Array),
typeof(List<String>),
typeof(IEnumerable<Char>) };
foreach (var t in types)
Console.WriteLine("{0,-15} IsArray = {1}", t.Name + ":",
t.IsArray);
}
}
// 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
open System
open System.Collections
let types =
[ typeof<String>; typeof<int[]>
typeof<ArrayList>; typeof<Array>
typeof<ResizeArray<string>>
typeof<seq<char>> ]
for t in types do
printfn $"""{t.Name + ":",-15} IsArray = {t.IsArray}"""
// 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

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)
Next
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
Remarks
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<T>.
To check for an array, use code such as:
typeof(Array).IsAssignableFrom(type)
GetType(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.
