Migrating from Delphi....

[Arda Han]

I am migrating my some applications from Delphi to C#. But...

Yes But I don't know C# professionally. I am using DLL in delphi like this :

.....
const
RFID_103_485IO = 'Cihaz.dll';

Function SearchPort (Prm1:LongWord) :LongWord; cdecl; External
RFID_103_485IO name 'SearchPort';
Function CheckPort (Prm1:LongWord) :LongWord; cdecl; External
RFID_103_485IO name 'CheckPort';
Function SearchReader (Prm1:LongWord; Prm2:LongWord) :LongWord; cdecl;
External RFID_103_485IO name 'SearchReader';
Function CheckReader (Prm1:LongWord; Prm2:LongWord) :LongWord; cdecl;
External RFID_103_485IO name 'CheckReader';

....

I am using it in Delphi :

.....
ResultNumber := CheckReader(n, m);

....

But how can I use my DLL functions in C#. I am trying below code in my
class. But it doesn't work. Could you help me ?

using System;

using System.Runtime. InteropServices ;

namespace MyDllLoadClass

{

public class Reader

{

[DllImport("Ciha z.dll", CallingConventi on=CallingConve ntion.Cdecl)]

static extern void SearchPort (uint Prm1);
[DllImport("Ciha z.dll", CallingConventi on=CallingConve ntion.Cdecl)]

static extern int CheckPort (uint Prm1);

[DllImport("Ciha z.dll", CallingConventi on=CallingConve ntion.Cdecl)]

static extern void SearchReader (uint Prm1, uint Prm2);

}

}

I am trying using this in my other class

label1.Text = Convert.ToStrin g(MyDllLoadClas s.Reader.CheckP ort(i));

oh dear doesn't sound good. Maybe I should leave IT and get myself a proper
career. I could one day aspire to getting my McDonalds 5 stars :D

Hopefully things will pick up, things seem to be improving but guess time
will tell.

IIRC (from reading his web site), Jon Skeet's in Cambridge. Maybe he
could hook you up? :-P

Nah - I *was* in Cambridge. I don't know of many C# jobs either - I'm
just happy to be in one :) (I'd be happy in another Java job, too...)
