public bool IsArray { get; }

Implements

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);
    }
}

This code produces the following output:

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