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 :)
