[英]How do you save selected ComboBox items into a .txt file
嗨，我是编程新手，我正在尝试使用WPF创建一个C＃等级计算器，以便用户输入他们的等级，并删除他们最低的2个等级，然后告诉他们他们的整体等级，我已经开始工作了但我希望将ComboBoxes中选定的成绩保存到txt文件中，也许可以再次将txt文件加载到成绩计算器中。
这是我到目前为止的代码

如果您在访问C：\\时遇到问题，则您的应用有权限问题。
尝试创建一个新文件夹“ C：\\ Test”，然后尝试在该文件夹中写入。 或以管理员身份启动Visual Studio。 还包括文件名
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void SaveButt_Click(object sender, RoutedEventArgs e)
{
File.WriteAllText("C:\\file.txt", "Hello World!");
