Getline Compile Error C2665

[Schwack]

I've just started learning C++ (got bored at work) and I'm using VC++ to compile some simple code but I get a compile error in test.cpp when using "getline". I've searched the internet and this forum but can't find an answer. I hope that someone can help :-)

test.h:

#include <iostream>
#include <fstream>
#include <string>
 
using namespace std;
 
class ReadFile
{
public:
    //Constructor
    ReadFile(string file_path = "\0") : text_file (file_path.c_str())
    {
        count = 0;
    };
 
    //Destructor
    ~ReadFile()
    {
        text_file.close();
    };
 
    long count;
    string line();
    bool end_of_file();
 
protected:
    ifstream text_file;
    string next_line;
 
};

test.cpp:

#include "test.h"
 
using namespace std;
 
string ReadFile::line()
 
    {
        if (! text_file.eof())
            {
                count += 1;
            }
 
        ifstream::getline(text_file,next_line); // Get a line from the text file 
        return next_line;
    }
 
bool ReadFile::end_of_file()
    {
        return text_file.eof(); // Check if it's the end of the file
    }

Ok, I figured it out - really dumb typo in line 13, test.cpp

ifstream::getline(text_file,next_line);

All I had to do was remove "ifstream::" so tha the line read:

getline(text_file,next_line);

I can't believe how long it took for me to spot that!!!
