I think that your last line should simply be
Dim attributeDataResultArray() As UAAttributeDataResult = EasyUAClient1.ReadMultiple(TagArray.ToArray)

Public TagArray As List(Of UAReadArguments)

TagArray.Add(New UAReadArguments(EndPointDescriptor.ToString, CurrentNodeDescriptor.ToString))

Dim attributeDataResultArray() As UAAttributeDataResult = EasyUAClient1.ReadMultiple(New UAReadArguments() {TagArray.ToArray})

This Code gives the error: Value of type 'UAReadArguments()' cannot be converted to 'UAReadArguments'

Hello,

I do not quite understand the question. Please try to provide more details and clarity about what you need to achieve. I will try below to explain at least something that may be related.

You can create arrays "on the fly" in .NET, and they are normal arrays that get passed to ReadMultiple.

If you prefer working with e.g. lists, you can create a List<>, and then do .ToArray() just before passing it to ReadMultiple.

Regards

I'm trying to ReadMultiple UA Tags with a dynamic list of tags but I'm unsure of how to go about it, is there anyway of either parsing a normal array to a ReadArguments array or is there a means of adding ReadArguments to a ReadArguments array
