DynamicUnionInstance.TrySetMember 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: 6.0.328+39e3229

Syntax

C#

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

Parameters

binder

Type: System.Dynamic.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

Type: System.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

Type: 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.)
