小编use*_*225的帖子

我正在尝试从二进制文件中读取字符串，但似乎无法使其正常工作。我是C ++的新手。有人可以帮忙吗？谢谢。

string Name = "Shaun";
unsigned short int StringLength = 0;

int main()
{
    StringLength = Name.size();

    ofstream oFile("File.txt", ios::binary|ios::out);
    oFile.write((char*)&StringLength, sizeof(unsigned short int));
    oFile.write(Name.c_str(), StringLength);
    oFile.close();

    StringLength = 0;
    Name = "NoName";

    ifstream iFile("File.txt", ios::binary|ios::in);
    if(!iFile.is_open())
        cout << "Failed" << endl;
    else
    {
        iFile.read((char *)&StringLength, sizeof(unsigned short int));
        iFile.read((char *)&Name, StringLength);
    }

    cout << StringLength << " " << Name << endl;

    system("Pause>NUL");
    return 0;
}
