Automation ArrayList in NAV 2013 R2

navuser1

Dear All,

How do I read the ArrayList of a custom dll in NAV 2013 R2 Environment ?

Please reply.

Look that :

Name DataType Subtype Length
NETArray DotNet System.Array.'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
NETTYpe DotNet System.Type.'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
NETConvert DotNet System.Convert.'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'

NETBufferLocal := NETBufferLocal.GetType('System.Buffer',FALSE);
NETTYpeLocal := NETTYpeLocal.GetType('System.Byte',FALSE);
NETArrayLocal := NETArrayLocal.CreateInstance(NETTYpeLocal, XMLText.LENGTH);
NETArrayLocal := Encoding.UTF8.GetBytes(XMLText);
MemoryStreamLocal := MemoryStream.MemoryStream(NETArrayLocal);
MemoryStreamLocal.Flush();
MemoryStreamLocal.Position := 0;

Could you be more clear.

My variable are :
Name DataType Subtype Length
csc Automation 'CSClb'.Class1

csc.ReadCardDetails ==>> ArrayList

Hi, sorry I have seen your replay now.

It's easy:

In my case, I had did to implement an array of byte, becouse I had had the necessity to send a file XML from NAV to NAV by a DLL C# .NET. In C# .NET I will writing this sentence :

byte[] readBuffer = new byte[4096];

to that in NAV you have to define in development environment this type of global variables.

Name DataType Subtype Length
NETArray DotNet System.Array.'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
NETTYpe DotNet System.Type.'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
NETConvert DotNet System.Convert.'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'

NETArray : Is a .NET namspace "System", in our case we have necessity of a subsidiary namespace "Array", so you make, in NAV, a
global variable "DotNet" finding "System.Array.'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"

NETTYpe : Is a .NET namspace "System", in our case we have necessity of a subsidiary namespace "Type"; you have necessity of this variable becouse when you will instance the array you must specify the type of array : byte (in my case), string, ecc

NETConvert : In my case I made a conversation from "Stream" to "String"

Well, now you can create your array, in the manner :

1) Define the type of array, in my case was of byte
NETTYpeLocal := NETTYpeLocal.GetType('System.Byte',FALSE);
2) Instancing the array specifying the type of arrya trought the variable "NETTYpeLocal" and specifying the lenght of array.
NETArrayLocal := NETArrayLocal.CreateInstance(NETTYpeLocal, XMLText.LENGTH);

Now you can use that, I convert my XML text in byte putting them in my array
NETArrayLocal := Encoding.UTF8.GetBytes(XMLText);

bye!! :-)
