DynamicValue.TryInvokeMember Method

Provides the implementation for operations that invoke a member. Classes derived from the DynamicObject class can override this method to specify dynamic behavior for operations such as calling a method.

Namespace: TwinCAT.TypeSystem
Assembly: TwinCAT.Ads (in TwinCAT.Ads.dll) Version: 6.0.328+39e3229

Syntax

C#

public override bool TryInvokeMember(
    InvokeMemberBinder binder,
    Object?[]? args,
    out Object?? result
)

Parameters

binder	Type: System.Dynamic.InvokeMemberBinder Provides information about the dynamic operation. The binder.Name property provides the name of the member on which the dynamic operation is performed. For example, for the statement sampleObject.SampleMethod(100), where sampleObject is an instance of the class derived from the DynamicObject class, binder.Name returns "SampleMethod". The binder.IgnoreCase property specifies whether the member name is case-sensitive.
args	Type: .System.Object. The arguments that are passed to the object member during the invoke operation. For example, for the statement sampleObject.SampleMethod(100), where sampleObject is derived from the DynamicObject class, args[0] is equal to 100.
result	Type: System.Object. The result of the member invocation.

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.)
