Note

Gets a value that indicates whether the type is an array.

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

Syntax

C++

public bool IsArray { get; }

Property Value

Type: System.Boolean

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

Implements

_Type.IsArray

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)

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 theIsArray 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
