visual-c++ - 使用 Visual C++ 在批处理文件中转义短划线字符

Question

我正在开发一个简单的程序，其中包含计算机名称的文件由 C++ 文件读取，如下所示：

//Previously, the file containing names was opened and 
//getline() is in use to read each line
//note that 'line' is a string containing the current line being read 

string comp = lower(trim(line.erase(0, 2)));

//lower converts to lowercase (for later in the program) and 
//trim trims the beginning and ends of the string.  
//I have erased the first two characters, since they contain two \'s
ofstream bat;
bat.open("names_get.bat");
if (bat.is_open()) {                                     
    bat << "wmic.exe /node:"+comp+" ComputerSystem Get UserName >CompNames.txt";
    bat.close();
}

这一切都运行得很好。但是，当使用 shellexecute 执行此批处理文件时，我遇到了问题。我的问题是命令提示符遇到计算机名称，例如“Owner-PC”并将 - 作为参数，导致无效的全局切换错误。有人可以指出我在这种情况下如何逃脱冲刺的正确方向。谢谢你，很抱歉这个问题很长！

你应该用Like包围你的comp名字"

 wmic.exe /node:"prefix-suffix" ComputerSystem Get Username

所以添加\"你的代码，它应该可以工作

if (bat.is_open()) {                                     
    bat << "wmic.exe /node:\""+comp+"\" ComputerSystem Get UserName >CompNames.txt";
    bat.close();
}
