What is the equivalent of C# #region in C++?

In C# you can hide your code, using regions, i.e. something like this. But it doesn't work in C++. What is the equivalent of the #region directive in C++?

#region Public methods

void SomeMethod()

{

}

#endregion

Solution: This should work in both .h/.cpp files in Visual Studio.

#pragma region

 void Test();

 void Test2();

 void Test3();

#pragma endregion

or with a comment like this:

#pragma region Region_Declarations

 void Test();

 void Test2();

 void Test3();

#pragma endregion Region_Declarations
