MethodBase.IsSpecialName Property

Definition

Namespace:

System.Reflection

Assembly:

System.Runtime.dll

Source:

MethodBase.cs

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

public:
 property bool IsSpecialName { bool get(); };

public bool IsSpecialName { get; }

member this.IsSpecialName : bool

Public ReadOnly Property IsSpecialName As Boolean

Property Value

Boolean

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

Examples

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

Remarks

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).
