Question

使用＆＃34; FILE *文件时遇到问题;＆＃34;在WP8上使用C ++。遇到上面的行时我的应用程序崩溃了。当我调试时，我看到：

 1. All the member of this variable "file" got message:
    (file)->_ptr: Unable to read memory.
    (file)->_cnt: Unable to read memory.
    (file)->_base: Unable to read memory.
    (file)->_flag: Unable to read memory.
    (file)->_file: Unable to read memory.
    (file)->_charbuf: Unable to read memory.
    (file)->_tmpfname: Unable to read memory.
    (file)->_bufsiz: Unable to read memory.

我不知道要解决它。

这是我使用的代码：

void SubMenu::LoadConfig(float dt)
{
    TiXmlDocument doc;
    bool flag = doc.LoadFile("Config\Config.xml");// Error here.
    TiXmlElement* root = doc.FirstChildElement();
    for (TiXmlElement* elem = root->FirstChildElement(); elem != NULL; elem = elem->NextSiblingElement())
    {
        std::string elemName = elem->Value();
        int Star = atoi(elem->GetText());
        if (elemName == "Tractor")
        {
            this->AddStarPoint(Level1, 4, Star);
        }
        if (elemName == "EggsCatch")
        {
            this->AddStarPoint(Level2, 3, Star);
        }
        if (elemName == "EggsCatch2")
        {
            this->AddStarPoint(Level3, 4, Star);
        }
    }
}

这是tinyxml.cpp获取函数LoadFile：

bool TiXmlDocument::LoadFile( const char* _filename, TiXmlEncoding encoding )
{
    TIXML_STRING filename( _filename );
    value = filename;

    // reading in binary mode so that tinyxml can normalize the EOL
    FILE* file = TiXmlFOpen( value.c_str (), "rb" ); // Error here. 

    if ( file )
    {
        bool result = LoadFile( file, encoding );
        fclose( file );
        return result;
    }
    else
    {
        SetError( TIXML_ERROR_OPENING_FILE, 0, 0, TIXML_ENCODING_UNKNOWN );
        return false;
    }
}

请帮忙！谢谢！

我认为file == NULL是因为路径中有一个反斜杠\。尝试

（更简单）用斜杠"Config/Config.xml"或
（更好）用另一个反斜杠"Config\\Config.xml"来逃避它。
