如何做登陆界面，登陆成功转入主窗体？？

Answer 1

你只要在登陆按钮的事件中写入你自己的验证逻辑，然后创建主窗体的实例，Show他并且关闭登陆窗就可以了：

登陆窗XAML:

<Window x:Class="WpfApplication20.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Login" Height="350" Width="525" SizeToContent="WidthAndHeight">
  <Grid>
    <Grid.RowDefinitions>
      <RowDefinition Height="auto"/>
      <RowDefinition Height="auto"/>
      <RowDefinition Height="auto"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
      <ColumnDefinition Width="auto"/>
      <ColumnDefinition Width="auto"/>
    </Grid.ColumnDefinitions>
    <TextBlock Text="User Name:" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    <TextBox Text="Please enter User Name" Grid.Column="1" Margin="2" BorderBrush="Gray" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    <TextBlock Text="Password:" Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    <PasswordBox Grid.Row="1" Grid.Column="1" Margin="2" BorderBrush="Gray" VerticalAlignment="Center"/>
    <Button Grid.Row="2" Grid.ColumnSpan="2" Content="Login" Click="Button_Click" HorizontalAlignment="Right" Margin="4"/>
  </Grid>
</Window>

登陆窗后台逻辑代码：

    private void Button_Click(object sender, RoutedEventArgs e)
    {
      // TO DO the user name and password validation....

      HelloWindow win = new HelloWindow();
      win.Show();
      this.Close();
    }
