DynamicUnionInstanceTrySetMember Method

Provides the implementation for operations that set member values. Classes derived from the DynamicObject class can override this method to specify dynamic behavior for operations such as setting a value for a property.


Namespace: TwinCAT.TypeSystem
Assembly: TwinCAT.Ads (in TwinCAT.Ads.dll) Version: 7.0.0+e56d35ccc4675faac24789a4aab60071fc61d470

Syntax

C#

public override bool TrySetMember(
    SetMemberBinder binder,
    Object? value
)

Parameters

binder  SetMemberBinder

Provides information about the object that called the dynamic operation. The binder.Name property provides the name of the member to which the value is being assigned. For example, for the statement sampleObject.SampleProperty = "Test", where sampleObject is an instance of the class derived from the DynamicObject class, binder.Name returns "SampleProperty". The binder.IgnoreCase property specifies whether the member name is case-sensitive.

value  Object

The value to set to the member. For example, for sampleObject.SampleProperty = "Test", where sampleObject is an instance of the class derived from the DynamicObject class, the value is "Test".

Return Value

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.)
