CLI,How to divide a class into multi-files(like c# partial)

[akira32]

How to divide a class into multi-files(like c# partial)? I want to divide class MainForm into multi-files? Could somebody tell me how do I achieve this goal?

namespace MyTools {
using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;
using namespace System::IO;
using namespace System::Globalization;//for NumberFormatInfo

vector<MyData> m_MyData;

public ref class MainForm : public System::Windows::Forms::Form
{

C++ or C++/CLI already supports this. One header file and several source files is possible. You can have a MainFormUI.cpp which includes MainForm.h and have methods like InitializeComponent. Another source file say MainForm.cpp which has all other method implementations. Unfortunately, VS designer won't support this kind of separation and it will always write the auto-generated code to MainForm.h.

A C# Partial Class is not equivalent to the C++ & C++/CLI header/source model. The following cannot not be done with C++ or C++/CLI in different (or in the same) files:

// In source file X:
public partial class Employee
{
public void DoWork()
{
}
}

// In source file Y
public partial class Employee
{
public void GoToLunch()
{
}
}

I never said they are equal.

Correct because it needs all the functions to be declared before using. The question here is How to divide a class into multi-files(like c# partial)? and I believe C++'s header and multiple source files model is the answer. Please correct me if you feel it is wrong. :)

It depends on the point of view, just having multiple physical files or having both multiple physical files and the method of class construction. Yes, you can use multiple files (header/source) in C++ as you do in C#. However, the C# partial class is constructed more like a C++ class-namespace hybrid where you can define methods and data members in multiple source files that somehow come together in the scope of one class.
