DynamicReferenceInstance.TryGetIndex Method

Provides the implementation for operations that get a value by index. Classes derived from the DynamicObject class can override this method to specify dynamic behavior for indexing operations.

Namespace: TwinCAT.TypeSystem
Assembly: TwinCAT.Ads (in TwinCAT.Ads.dll) Version: 4.3.0.0

Syntax

C#

public override bool TryGetIndex(
    GetIndexBinder binder,
    Object[] indexes,
    out Object result
)

VB

Public Overrides Function TryGetIndex ( 
    binder As GetIndexBinder,
    indexes As Object(),
    <OutAttribute> ByRef result As Object
) As Boolean

Parameters

binder	Type: System.Dynamic.GetIndexBinder Provides information about the operation.
indexes	Type: .System.Object. The indexes that are used in the operation. For example, for the sampleObject[3] operation in C# (sampleObject(3) in Visual Basic), where sampleObject is derived from the DynamicObject class, indexes[0] is equal to 3.
result	Type: System.Object. The result of the index operation.

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 run-time exception is thrown.)
