Hello;
I want to refactor this method by extracting:
InfoOrdreDirect_5013 directOrder = new InfoOrdreDirect_5013();
directOrder.put_AIS(0, e_Type_Lecteur_CB.Type_Lecteur_CB_Satellite);
as a parameter, so I started with a delegate but it does not work

C#

        /// Autozero Methode
        /// 
        private void AutozeroPosition()
        {
            InfoOrdreDirect_5013 directOrder = new InfoOrdreDirect_5013();
            directOrder.put_AIS(0, e_Type_Lecteur_CB.Type_Lecteur_CB_Satellite);
            IInfoReponse_CRO reponseCro = null;

            try
            {
                reponseCro = this._espCom.SendCmd(directOrder);
                if (reponseCro != null && true/*== e_Succes_Echec.Succes_Echec_Succes*/)
                {

                }
               
            }
            catch (Exception ex)
            {
                Thread.Sleep(1000);
                throw new System.Runtime.InteropServices.COMException(ex.Message);
            }
        }



My refactoring:
private delegate IInfoOrdreDirect InfoOrderDelegate(int a, Enum pegase);
        //public void InvokeInfoOrderDelegate(Delegate method, object[] param)
        //{
        //   method.DynamicInvoke(param);
        //}


        /// <summary>
        /// Autozero Methode
        /// </summary>
        private void AutozeroPosition(InfoOrdreDirect info, Delegate method, object[] param)
        {
            //InfoOrdreDirect_5013 directOrder = new InfoOrdreDirect_5013();
            //info.put_AIS(0, e_Type_Lecteur_CB.Type_Lecteur_CB_Satellite);
            method.DynamicInvoke(param);
            object infoReponseCro;
            try
            {
                infoReponseCro = _espCom.SendCmd(info) as InfoReponse_CRO;
                if (infoReponseCro != null && true/*== e_Succes_Echec.Succes_Echec_Succes*/)
                {

                }
            }
            catch (Exception ex)
            {
                Thread.Sleep(1000);
                throw new System.Runtime.InteropServices.COMException(ex.Message);
            }


        }

My invoking:

C#

InfoOrdreDirect_5013 info = new InfoOrdreDirect_5013();

           AutozeroPosition(info, new InfoOrderDelegate(info.put_AIS),new object[] { 0, e_Type_Lecteur_CB.Type_Lecteur_CB_Satellite });

My error:
On put_ais:

Expected a method with infoOrderDirect put_ais(int, enum) signature.

Any Idea how to refactor the AutozeroPosition() ?
Thanks.

Solution 2

The problem was a simple casting problem from int32 to int 16, I added (short)0 casting.

C#

public class Class1
{
    public int Method1(string input)
    {
        //... do something
        return 0;
    }

    public int Method2(string input)
    {
        //... do something different
        return 1;
    }

    public bool RunTheMethod(Func<string,> myMethodName)
    {
        //... do stuff
        int i = myMethodName("My String");
        //... do more stuff
        return true;
    }

    public bool Test()
    {
        return RunTheMethod(Method1);
    }
