while (getline(is, textline)) 这个函数编译报错

[caimeisheng]

error C2667: 'getline' : none of 2 overload have a best conversion
error C2668: 'getline' : ambiguous call to overloaded function
fatal error C1903: unable to recover from previous error(s); stopping compilation

lz直接贴代码不好么？

getline
template<class E, class T, class A>
    basic_istream<E, T>& getline(
        basic_istream <E, T>& is,
        basic_string<E, T, A>& str);
template<class E, class T, class A>
    basic_istream<E, T>& getline(
        basic_istream <E, T>& is,
        basic_string<E, T, A>& str,
        E delim);
The first template function returns getline(is, str, is.widen('\n')). 

The second template function replaces the sequence controlled by str with a sequence of elements extracted from the stream is. In order of testing, extraction stops:

At end of file. 
After the function extracts an element that compares equal to delim, in which case the element is neither put back nor appended to the controlled sequence. 
After the function extracts is.max_size() elements, in which case the function calls setstate(ios_base::failbit). 
If the function extracts no elements, it calls setstate(failbit). In any case, it returns *this.

See the related sample program.
