Type::IsValueType Property

public:
virtual property bool IsValueType {
	bool get () sealed;
}

Implements

Value types are types that are represented as sequences of bits; value types are not classes or interfaces. Value types are referred to as "structs" in some programming languages. Enums are a special case of value types.

This property returns false for the ValueType class, because ValueType is not a value type itself. It is the base class for all value types, and therefore any value type can be assigned to it. This would not be possible if ValueType itself was a value type. Value types are boxed when they are assigned to a field of type ValueType.

This property returns true for enumerations, but not for the Enum type itself. For an example that demonstrates this behavior, see IsEnum.

This property is read-only.

The following example creates a variable of type MyEnum, checks for the IsValueType property, and displays the result.

using namespace System;

// Declare an enum type.
enum class MyEnum
{
   One, Two
};

int main()
{
   try
   {
      bool myBool = false;
      MyEnum myTestEnum = MyEnum::One;

      // Get the type of myTestEnum.
      Type^ myType = myTestEnum.GetType();

      // Get the IsValueType property of the myTestEnum
      // variable.
      myBool = myType->IsValueType;
      Console::WriteLine( "\nIs {0} a value type? {1}.", myType->FullName, myBool );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "\nAn exception occurred: {0}", e->Message );
   }

}
