sir YUN ZHU Thank you very much for helping me

I wrote the following code to read the class inside the DLL,
DLL Name :
IntegrationInvoiceJOD
Class Name:
GeneralReturnInvoice
inside Class "GeneralReturnInvoice" in C#:
Public Function JustTest() As String
Return "Welcom "
End Function
====================================================
Success: The package is created.
and giving me an error :

============================================

dotnet
{
assembly(IntegrationInvoiceJOD)
{
type(IntegrationInvoiceJOD.GeneralReturnInvoice;VAR_Test) { }
}
}
pageextension 50100 "Sales Order Ext" extends "Sales Order"
{
trigger OnOpenPage();
var
justTestInstance: DotNet VAR_Test;

begin
justTestInstance := justTestInstance.GeneralReturnInvoice();
Message('Hello, world! It is: %1', justTestInstance.ToString());
end;
}
============================================

I want the correct way to call the class from the DLL without Error ??????
