silverlight将文本框保存为xml [英] silverlight save textbox to xml

问题描述

我的项目看起来像这样， http://s23.postimg.org/mrhuocn4b/asd。 png

我已经可以使用以下代码将文本框保存到xml文件：

  private void SaveFile（object sender，RoutedEventArgs e）
 {
 
 SaveFileDialog saveFileDialog = new SaveFileDialog（）; 
 
 saveFileDialog.DefaultExt =xml; 
 saveFileDialog.Filter =XML文件（* .xml）| * .xml |所有文件（*。*）| *。*; 
 saveFileDialog.FilterIndex = 1; 
 
 if（saveFileDialog.ShowDialog（）== true）
 {
 
 
使用（Stream stream = saveFileDialog.OpenFile（））
 {
 
 StreamWriter sw = new StreamWriter（stream，System.Text.Encoding.UTF8）; 
 sw.Write（GetGeneratedXML（）。ToString（））; 
 sw.Close（）; 
 
 stream.Close（）; 
 
} 
 
} 
} 
 
 
私人XElement GetGeneratedXML（）
 {
 
 XElement userInformation = new XElement（names）; 
 userInformation.Add（new XElement（first，box1.Text））; 
 // userInformation.Add（new XElement（last，lastNameText.Text））; 
 
 return userInformation; 
 
} 
  

但是这是从已经在XAML中创建的文本框（那个我只是用于测试），我想要的是保存通过单击按钮创建的所有文本框的文本。

这是如何创建文本框架： / p>

XAML：

 < TextBox Text ={Binding Header， UpdateSourceTrigger = PropertyChanged}
 BorderBrush =黑色BorderThickness =1/> 
< TextBox Text ={Binding Text，UpdateSourceTrigger = PropertyChanged}
 TextWrapping =Wrap
 VerticalScrollBarVisibility =Auto
 AcceptsReturn =True
 BorderBrush =BlackBorderThickness =1Grid.Row =1/> 
  

C＃：

 code> private void b_ClickEntidade（object sender，RoutedEventArgs e）
 {
 MyBox c = new MyBox（）; 
 c.Header =Entidade; 
 c.Text =Atributos; 
 c.Margin = new Thickness（10）; 
 c.BorderThickness = new Thickness（1）; 
 LayoutRoot.Children.Add（c）; 
 c.MouseLeftButtonDown + = Handle_MouseDownEntidade; 
 c.MouseMove + = Handle_MouseMoveEntidade; 
 c.MouseLeftButtonUp + = Handle_MouseUpEntidade; 
 Canvas.SetLeft（c，250）; 
 Canvas.SetTop（c，40）; 
} 
  

编辑-----------

这是MyBox.cs

  public partial class MyBox：UserControl 
 {
 public static readonly DependencyProperty HeaderProperty = DependencyProperty.Register（Header，typeof（string），typeof（MyBox），null）; 
 public static readonly DependencyProperty TextProperty = DependencyProperty.Register（Content，typeof（string），typeof（MyBox），null）; 
 
 public string Header 
 {
 get {return GetValue（HeaderProperty）as string; } 
 set {SetValue（HeaderProperty，value）; 
} 
 
 public string Text 
 {
 get {return GetValue（TextProperty）as string; } 
 set {SetValue（TextProperty，value）; } 
} 
 
 public MyBox（）
 {
 InitializeComponent（）; 
 
 this.DataContext = this; 
 
} 
} 
} 
  

解决方案

只需跟踪列表中的所有框：

  IList< MyBox> box = new List< MyBox>（）; 
 
 private void b_ClickEntidade（object sender，RoutedEventArgs e）
 {
 MyBox c = new MyBox（）; 
 c.Header =Entidade; 
 c.Text =Atributos; 
 
 ... 
 
 boxes.Add（c）; 
} 
  

然后生成整个XML：

  private XElement GetGeneratedXML（）
 {
 XElement userInformation = new XElement（names）; 
 
 foreach（框中的MyBox b）
 {
 userInformation.Add（new XElement（first，b.Text））; 
} 
 
 return userInformation; 
} 
  

my project looks like this, http://s23.postimg.org/mrhuocn4b/asd.png

and I already can save a textbox to xml file, using this code:

private void SaveFile(object sender, RoutedEventArgs e)
    {

        SaveFileDialog saveFileDialog = new SaveFileDialog();

        saveFileDialog.DefaultExt = "xml";
        saveFileDialog.Filter = "XML Files (*.xml)|*.xml|All files (*.*)|*.*";
        saveFileDialog.FilterIndex = 1;

        if (saveFileDialog.ShowDialog() == true)
        {


            using (Stream stream = saveFileDialog.OpenFile())
            {

                StreamWriter sw = new StreamWriter(stream, System.Text.Encoding.UTF8);
                sw.Write(GetGeneratedXML().ToString());
                sw.Close();

                stream.Close();

            } 

        }
                }


    private XElement GetGeneratedXML()
    {

        XElement userInformation = new XElement("names");
        userInformation.Add(new XElement("first", box1.Text));
       // userInformation.Add(new XElement("last", lastNameText.Text));

        return userInformation;

    }

But this is from a textbox already created in XAML (that I used just for testing), and what I want is to save the text's of all the textboxes created by clicking the buttons.

THIS IS HOW I CREATE THE TEXTBOXES:

XAML:

<TextBox Text="{Binding Header,UpdateSourceTrigger=PropertyChanged}"
                 BorderBrush="Black" BorderThickness="1" />
        <TextBox Text="{Binding Text,UpdateSourceTrigger=PropertyChanged}"
                 TextWrapping="Wrap"
                 VerticalScrollBarVisibility="Auto"
                 AcceptsReturn="True"
                 BorderBrush="Black" BorderThickness="1" Grid.Row="1" />

C#:

private void b_ClickEntidade(object sender, RoutedEventArgs e)
        {
            MyBox c = new MyBox();
            c.Header = "Entidade";
            c.Text = "Atributos";
            c.Margin = new Thickness(10);
            c.BorderThickness = new Thickness(1);
            LayoutRoot.Children.Add(c);
            c.MouseLeftButtonDown += Handle_MouseDownEntidade;
            c.MouseMove += Handle_MouseMoveEntidade;
            c.MouseLeftButtonUp += Handle_MouseUpEntidade;
            Canvas.SetLeft(c, 250);
            Canvas.SetTop(c, 40);
        } 

EDIT -----------

THIS IS MyBox.cs

    public partial class MyBox : UserControl
    {
        public static readonly DependencyProperty HeaderProperty = DependencyProperty.Register("Header", typeof(string), typeof(MyBox),null);
        public static readonly DependencyProperty TextProperty = DependencyProperty.Register("Content", typeof(string), typeof(MyBox), null);

        public string Header
        {
            get { return GetValue(HeaderProperty) as string; }
            set { SetValue(HeaderProperty, value); }
        }

        public string Text
        {
            get { return GetValue(TextProperty) as string; }
            set { SetValue(TextProperty, value); }
        }

        public MyBox()
        {
            InitializeComponent();

            this.DataContext = this;

        }  
    }
}

解决方案

Just keep track of all the boxes in a list:

IList<MyBox> boxes = new List<MyBox>();

private void b_ClickEntidade(object sender, RoutedEventArgs e)
{
    MyBox c = new MyBox();
    c.Header = "Entidade";
    c.Text = "Atributos";

    ...

    boxes.Add(c);
} 

Then generate the whole XML:

private XElement GetGeneratedXML()
{
    XElement userInformation = new XElement("names");

    foreach (MyBox b in boxes)
    {        
        userInformation.Add(new XElement("first", b.Text));
    }

    return userInformation;
}
