Type.IsArray Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets a value indicating whether the Type is an array.

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

Syntax

'Declaration
Public ReadOnly Property IsArray As Boolean

public bool IsArray { get; }

Property Value

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

Remarks

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.

Examples

The following example demonstrates using the IsArray property.

Note:
To run this example, see Building Examples That Use a Demo Method and a TextBlock Control.


Class Example
   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      Dim array As Integer() = {1, 2, 3, 4}
      Dim at As Type = GetType(Array)
      Dim t As Type = array.GetType()
      outputBlock.Text += String.Format("The type is {0}. Is this type an array? {1}", at, at.IsArray) & vbCrLf
      outputBlock.Text += String.Format("The type is {0}. Is this type an array? {1}", t, t.IsArray) & vbCrLf
   End Sub 'Main
End Class 'TestType

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
