[英]c# Wp8: error in getting textbox entered value?
它說createPassword
和repeatPassword
不在當前上下文中。 為什么會發生什么?
碼;
public MainPage()
{
InitializeComponent();
TextBox createPassword = new TextBox();
createPassword.Width = 400;
TextBox repeatPassword = new TextBox();
repeatPassword.Width = 400;
Button createButton = new Button();
createButton.Content = "Create New Password";
createButton.Click += new RoutedEventHandler(savePassword);
StackPanel content = new StackPanel();
content.HorizontalAlignment = HorizontalAlignment.Center;
content.Children.Add(createPassword);
content.Children.Add(repeatPassword);
content.Children.Add(createButton);
LayoutRoot.Children.Add(content);
}
void savePassword(object sender, RoutedEventArgs e)
{
string password1 = createPassword.Text;
string password2 = repeatPassword.Text;
}
createPassword
和repeatPassword
必須是類成員才能在不同的類方法中使用它們:
TextBox createPassword;
TextBox repeatPassword;
public MainPage()
{
InitializeComponent();
createPassword = new TextBox();
createPassword.Width = 400;
repeatPassword = new TextBox();
repeatPassword.Width = 400;
Button createButton = new Button();
createButton.Content = "Create New Password";
createButton.Click += new RoutedEventHandler(savePassword);
StackPanel content = new StackPanel();
content.HorizontalAlignment = HorizontalAlignment.Center;
content.Children.Add(createPassword);
content.Children.Add(repeatPassword);
content.Children.Add(createButton);
LayoutRoot.Children.Add(content);
}
void savePassword(object sender, RoutedEventArgs e)
{
string password1 = createPassword.Text;
string password2 = repeatPassword.Text;
}
