我在MongoDB Shell中执行db.myCollectionname.remove（{}），但是我错误地运行了命令db.myCollectionname.remove，并且mongoDB在控制台中向我展示了以下方法。
private void OnModeChosen(object sender, EventArgs e)
{
Country country = ((Country)(picker.SelectedItem)) // get the country object from the picker
picker2.ItemsSource = GetRegions(country.CountryId ) // call the function to get the regions for that country
picker2.ItemDisplayBinding = New Binding("RegionsName")
picker2.SelectedIndex = 0 // not sure why I did this, I think to make sure an item was selected
stackpicker2.IsVisible = true // make the stack layout visible with the 2nd picker
picker2.IsEnabled = true;
}
这似乎是一个java脚本方法？它是一个Node.js方法吗？请澄清。
