ObsoleteAttribute::IsError Property

 

Gets a Boolean value indicating whether the compiler will treat usage of the obsolete program element as an error.

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

public:

	bool get();
}

Property Value

Type: System::Boolean

true if the obsolete element usage is considered an error; otherwise, false. The default is false.

The following example defines a class that contains two members marked as obsolete. The first, a property named OldProperty, produces a compiler warning if it is called. The second, a method named CallOldMethod, produces a compiler error. The example uses reflection to get information about the ObsoleteAttribute attributes applied to members of the type and displays the values of their Message and IsError properties.
