D365FFO - Richiamare metodi privati all'esterno della classe

Questo link mostra come usare la  reflection del C# per richiamare metodi privati statici o di istanza di una determinata classe in AX.

Supponiamo di avere una classe fatta così:

 class MyClass  
 {  
      private static int sumPrivate(int a, int b)  
      {  
           return a+b;  
      }  
   
      private int sumInstancePrivate(int a, int b)  
      {  
           return a+b;  
      }  
 }  

possiamo accedere ai due metodi privati così:

 using System.Reflection;  
   
 class testReflection  
 {  
   public static void main(Args _args)  
   {  
     int      ret;  
     System.Object[] parametersArray = new System.Object[2]();  
     parametersArray.SetValue(5, 0);  
     parametersArray.SetValue(2, 1);  
       
     System.Type   myType;  
     DictClass    dt = new DictClass(classNum(MyClass));  
     Object     classInstance = dt.makeObject();  
             
     var bindFlags = BindingFlags::InvokeMethod |   
                               BindingFlags::NonPublic |   
                               BindingFlags::Static | BindingFlags::Instance;  
     
     myType = classInstance.GetType();  
   
     //richiama il metodo statico  
     ret = myType.InvokeMember(staticMethodStr(MyClass,sumPrivate),bindFlags,null,null,parametersArray);  
   
     //richiama il un metodo di instanza  
     var methodInfo = myType.GetMethod(methodStr(MyClass, sumInstancePrivate), bindFlags);  
   
     if (methodInfo)  
     {  
                // Or use “new System.Object[0]()” instead of parametersArray if you do not have any parameters  
       ret = methodInfo.Invoke(classInstance, parametersArray);   
     }  
   }  
 }  

Con questo metodo possiamo invece richiamare un metodo privato statico su una tabella.

   NumberSequenceTable numSeqTab;  
  System.Reflection.MethodInfo mi;  
  System.Object[] parametersArray = new System.Object[3]();  
   
  NumberSequenceReference   NumberSequenceReference;  
  NumberSequenceGroupId    NumberSequenceGroupId = "abc";  
  TransDate          invoiceDate = today();  
   
  select firstonly NumberSequenceReference;  
   
  parametersArray.SetValue(invoiceDate, 0);  
  parametersArray.SetValue(NumberSequenceReference, 1);  
  parametersArray.SetValue(NumberSequenceGroupId, 2);  
    
  System.Type  myType;  
  dictTable  dt = new dictTable(tableNum(CustInvoiceJour));  
  common   classInstance = dt.makeRecord();  
       
  var bindFlags = BindingFlags::InvokeMethod |  
              BindingFlags::NonPublic |  
              BindingFlags::Static | BindingFlags::Instance;  
      
  myType = classInstance.GetType();  
   
  mi = myType.GetMethod(tableStaticMethodStr(CustInvoiceJour,getNumberSequenceTableForChronologicalDateValidation_W), bindFlags);  
   
  numSeqTab = mi.Invoke(null, parametersArray);  

N:B: Mina le basi della programmazione ad oggetti :)
