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.

Implements

_Type.IsClass

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 MyTypeClass
{
    public static void Main(string[] args)
    {
        try
        {
            Type  myType = typeof(MyDemoClass);
            // Get and display the 'IsClass' property of the 'MyDemoClass' instance.
            Console.WriteLine("\nIs the specified type a class? {0}.", myType.IsClass); 
        }
        catch(Exception e)
        {
            Console.WriteLine("\nAn exception occurred: {0}." ,e.Message);
        }
    }
}
