GrapeCity.Documents.Pdf.Spec.IPdfArrayExt.TryGet

TryGet Method

TryGet<T>(IPdfArray, int, out T, out bool, bool)

Tries to get the value at the specified index. Returns true if value exists and can be converted to a T, resolves a PDF reference if needed. Note! The method does not resolve reference if T is IPdfRef, otherwise the method resolves the reference and returns actual object.

public static bool TryGet<T>(this IPdfArray array, int index, out T value, out bool isNull, bool addWarning) where T : IPdfObject

Public Shared Function TryGet(Of T As IPdfObject)(array As IPdfArray, index As Integer, ByRef value As T, ByRef isNull As Boolean, addWarning As Boolean) As Boolean

Parameters
