DynamicObject.TryDeleteMember Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Provides the implementation for operations that delete an object member. This method is not intended for use in C# or Visual Basic.

Namespace:  System.Dynamic
Assembly:  System.Core (in System.Core.dll)

Syntax

'Declaration
Public Overridable Function TryDeleteMember ( _
    binder As DeleteMemberBinder _
) As Boolean

public virtual bool TryDeleteMember(
    DeleteMemberBinder binder
)

Parameters

Return Value

Type: System.Boolean
true if the operation is successful; otherwise, false. If this method returns false, the run-time binder of the language determines the behavior. (In most cases, a language-specific run-time exception is thrown.)

Remarks

Classes derived from the DynamicObject class can override this method to specify how an object member should be deleted. When this method is not overridden, the run-time binder of the language determines the behavior. (In most cases, a language-specific run-time exception is thrown.)

C# and Visual Basic compilers never emit code to use this method because they do not support this kind of operation. This method is intended for languages that support syntax for deleting members, such as del sampleObject.SampleMember in Python.
