推荐答案

我认为有两个选择.第一种是在文本模式下打开文件，然后一次读取一行，并将每一行追加到您的字符串中:

I think that there are two options. The first is to open the file in text mode and then read a line at a time, appending each line to your string:

std::string result;
std::ifstream file("myfile.xsd");
if(file.is_open())
{
  while(file.good())
  {
    std::string temp;
    std::getline(file, temp);
    result.append(temp);
  }
  file.close();
}

第二种方法是将其视为二进制文件，将其读入内存，然后分配给字符串.如果文件很大或有很多行，此方法可能会更有效.

The second way is to treat it as a binary file, read it into memory and then assign to a string. This method may be more efficient if your file is large or has a lot of lines.

std::string result;
char* memblock;
std::ifstream file("myfile.xsd", std::ios::in|std::ios::binary|std::ios::ate);
if (file.is_open())
{
  std::ifstream::pos_type size = file.tellg();
  memblock = new char[size];
  file.seekg(0, std::ios::beg);
  file.read(memblock, size);
  file.close();
  result.assign(memblock, size);
  delete[] memblock;
}
