如何在没有丢失链接的数据库中保存WPF RichTextBox？

我在Richtextbox中有一个链接并且它运行良好但是如果我将Richtextbox保存到数据库中然后加载它要删除的链接我只能看到该链接的文本

例如我的Richtextbox有底部文字：

这是一个链接

但在保存并再次加载后我才能看到文字：

这是一个链接

从所选文本动态创建的超链接如下：

RichTextBox.IsDocumentEnabled = true; RichTextBox.IsReadOnly = true; Run run = new Run(RichTextBox.Selection.Text); Hyperlink hyp = new Hyperlink(run) { TargetName = run.Text }; TERM.WordMain main = new TERM.WordMain(); hyp.Click += new RoutedEventHandler(main.hyperLink_Click); hyp.NavigateUri = new Uri("http://search.msn.com"); RichTextBox.Cut(); var container = new InlineUIContainer(new TextBlock(hyp), RichTextBox.Selection.Start); RichTextBox.IsDocumentEnabled = true; RichTextBox.IsReadOnly = false; 

将RTF格式的richtextbox内容保存到文本字段：

  public static string ToStringFromBytes(System.Windows.Controls.RichTextBox richTextBox) { if (richTextBox.Document.Blocks.Count == 0) { return null; } MemoryStream memoryStream = new MemoryStream(); TextRange textRange = new TextRange(richTextBox.Document.ContentStart, richTextBox.Document.ContentEnd); textRange.Save(memoryStream, System.Windows.DataFormats.Rtf); return Encoding.UTF8.GetString(memoryStream.ToArray()); } 

并从数据库加载到flowdocument

 public static FlowDocument LoadFromString(string s) { try { byte[] byteArray = Encoding.UTF8.GetBytes(s); MemoryStream stream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(s)); FlowDocument doc = new FlowDocument(); TextRange textRange = new TextRange(doc.ContentStart, doc.ContentEnd); textRange.Load(stream, System.Windows.DataFormats.Rtf); return doc; } catch (Exception ex) { throw; } }

以下示例似乎可以解决问题。

在这里，我加载并保存XAML而不是rtf格式的文本。 另请注意，您需要在加载后将超链接的处理程序添加回元素，因为它们不会被序列化。

 public partial class MainWindow : Window { private const string _stateFile = "state.xaml"; public MainWindow() { InitializeComponent(); richTextBox.IsReadOnly = false; } private void createLinkButton_Click(object sender, RoutedEventArgs e) { richTextBox.IsDocumentEnabled = false; richTextBox.IsReadOnly = true; var textRange = richTextBox.Selection; var hyperlink = new Hyperlink(textRange.Start, textRange.End); hyperlink.TargetName = "value"; hyperlink.NavigateUri = new Uri("http://search.msn.com"); hyperlink.RequestNavigate += HyperlinkOnRequestNavigate; richTextBox.IsDocumentEnabled = true; richTextBox.IsReadOnly = false; } private void HyperlinkOnRequestNavigate(object sender, RequestNavigateEventArgs args) { // Outputs: "Requesting: http://search.msn.com, target=value" Console.WriteLine("Requesting: {0}, target={1}", args.Uri, args.Target); } private void SaveXamlPackage(string filePath) { var range = new TextRange(richTextBox.Document.ContentStart, richTextBox.Document.ContentEnd); var fStream = new FileStream(filePath, FileMode.Create); range.Save(fStream, DataFormats.XamlPackage); fStream.Close(); } void LoadXamlPackage(string filePath) { if (File.Exists(filePath)) { var range = new TextRange(richTextBox.Document.ContentStart, richTextBox.Document.ContentEnd); var fStream = new FileStream(filePath, FileMode.OpenOrCreate); range.Load(fStream, DataFormats.XamlPackage); fStream.Close(); } // Reapply event handling to hyperlinks after loading, since these are not saved: foreach (var paragraph in richTextBox.Document.Blocks.OfType()) { foreach (var hyperlink in paragraph.Inlines.OfType()) { hyperlink.RequestNavigate += HyperlinkOnRequestNavigate; } } } private void saveButton_Click(object sender, RoutedEventArgs e) { SaveXamlPackage(_stateFile); } private void loadButton_Click(object sender, RoutedEventArgs e) { LoadXamlPackage(_stateFile); } }
