我想从MainWindow()中调用函数ShowWindowCommand()和HideWindowCommand()。
我有以下课程:
string line = "Rok rok irrelevant text irrelevant;text.irrelevant,text";
string NewLine = Regex.Replace(line, @"\b[rR]\w*", "");
通常,从NotifyIconRessource.xaml的上下文菜单中调用ShowWindowCommand()和HideWindowsCommand()
public class NotifyIconViewModel
{
public ICommand ShowWindowCommand
{
get
{
return new DelegateCommand
{
CanExecuteFunc = () => Application.Current.MainWindow == null,
CommandAction = () =>
{
Application.Current.MainWindow = new WorkingTimer.MainWindow();
Application.Current.MainWindow.Show();
}
};
}
}
public ICommand HideWindowCommand
{
get
{
return new DelegateCommand
{
CommandAction = () => Application.Current.MainWindow.Close(),
CanExecuteFunc = () => Application.Current.MainWindow != null
};
}
}
我该怎么做?

您首先必须创建该类的公共属性,然后将其设置为视图的数据上下文:
public NotifyIconViewModel NotifyIconVM { get; set; }
MainWindow()
{
InitializeComponent();
NotifyIconVM = new NotifyIconViewModel();
DataContext = NotifyIconVM;
}
设置数据上下文将告诉视图在哪里查找命令。
