Type.IsArray Property

May 11, 2014

Gets a value indicating whether the Type is an array.

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

public bool IsArray { get; }

Property Value

Type: System.Boolean
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 Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      int[] array = { 1, 2, 3, 4 };
      Type at = typeof(Array);
      Type t = array.GetType();
      outputBlock.Text += String.Format("The type is {0}. Is this type an array? {1}", at, at.IsArray) + "\n";
      outputBlock.Text += String.Format("The type is {0}. Is this type an array? {1}", t, t.IsArray) + "\n";
   }
}


This code produces the following output:

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