IsArray Property

Type.IsArray Property

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Gets a value indicating whether the Type is an array.

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

Public ReadOnly Property IsArray As Boolean

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.

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

This code produces the following output:

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