Type.IsClass Property

Gets a value indicating whether the Type is a class; that is, not a value type or interface.

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

public bool IsClass { get; }

Property Value

Type: System.Boolean
true if the Type is a class; otherwise, false.

This property returns true for Type instances representing Enum and ValueType.

The ClassSemanticsMask distinguishes a type declaration as class, interface, or value type.

If the current Type represents a constructed generic type, this property returns true if the generic type definition is a class definition; that is, it does not define an interface or a value type.

If the current Type represents 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 creates an instance of a type and indicates whether the type is a class.


using System;
using System.Reflection;

public class MyDemoClass
{
}

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      try
      {
         Type myType = typeof(MyDemoClass);
         // Get and display the 'IsClass' property of the 'MyDemoClass' instance.
         outputBlock.Text += String.Format("\nIs the specified type a class? {0}.", myType.IsClass) + "\n";
      }
      catch (Exception e)
      {
         outputBlock.Text += String.Format("\nAn exception occurred: {0}.", e.Message) + "\n";
      }
   }
}
