MethodBase.IsSpecialName Property

Gets a value indicating whether this method has a special name.

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

public bool IsSpecialName { get; }
/** @property */
public final boolean get_IsSpecialName ()

public final function get IsSpecialName () : boolean

Property Value

true if this method has a special name; otherwise, false.

The SpecialName bit is set to flag members that are treated in a special way by some compilers (such as property accessors and operator overloading methods).

This example shows a use of IsSpecialName to filter internal or private members out of a list.
