Refering within the class to constructor with the this pointer

#include "stdafx.h"
ref class station{
public:
    station(){
    };
    void wrapper_1()
    {
        this->somefunct(); /*happy*/
    };
    void wrapper_2()
    {
        this->station(); /*not happy*/
    };
    void somefunct(){
        System::Console::WriteLine(L"abcde");
    };
};

int main(array<System::String^>^ args)
{
    station^ temp_1 = gcnew station();
    temp_1->wrapper_1();
    System::Console::ReadLine();
};

Many people are asking me why I would want to call the constructor from a function within my class. This is why

I want to have an overloaded constructor so one constructor is parameterless and sets a default values to pass on to my main constructor because managed constructors parameters cannot contain have default values. And I wanted default values for my constructor parameters. Below is my example for further clarity:

#include"stdafx.h"
ref class station{
public:
    station(int par_1,int par_2)
    {
        int sum= par_1 + par_2;
        System::Console::WriteLine(System::Convert::ToString(sum));
//default value output 13
    };
    station(){
        int pass_1=5;
        int pass_2=8;
        station(pass_1,pass_2); /*But why couldn't I use this->station(pass_1,pass_2);*/
    };
};
int main(array<System::String^>^ args)
{
    station^ obj= gcnew station();
    System::Console::ReadLine();
};
