Type.IsArray Property

Gets a value indicating whether the Type is an array.

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

public bool IsArray { get; }
/** @property */
public final boolean get_IsArray ()

public final function get IsArray () : boolean

Property Value

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

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.

The following example demonstrates using the IsArray property.

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);
    }
}

import System.*;

class TestIsArray
{
    public static void main(String[] args)
    {
        int array[] =  { 1, 2, 3, 4 };
        Type at = Array.class.ToType();
        Type t = array.GetType();
        Console.WriteLine("The type is {0}. Is this type an array? {1}",
            System.Convert.ToString(at),
            System.Convert.ToString(at.get_IsArray()));
        Console.WriteLine("The type is {0}. Is this type an array? {1}", 
            System.Convert.ToString(t),
            System.Convert.ToString(t.get_IsArray()));
    } //main
} //TestIsArray

This code produces the following output:

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