WPF操做RichTextBox

取出richTextBox裏面的內容
第一種方法：將richTextBox的內容以字符串的形式取出

string xw = System.Windows.Markup.XamlWriter.Save(richTextBox.Document);

第二種方法：將richTextBox的類容以二進制數據的方法取出

FlowDocument document = richTextBox.Document;
System.IO.Stream s = new System.IO.MemoryStream(); 
System.Windows.Markup.XamlWriter.Save(document, s); 
byte[] data = new byte[s.Length];
s.Position = 0;
s.Read(data, 0, data.Length);
s.Close();

 

賦值給richTextBox
第一種方法：將字符串轉換爲數據流賦值給richTextBox中

System.IO.StringReader sr = new System.IO.StringReader(xw);
System.Xml.XmlReader xr = System.Xml.XmlReader.Create(sr);
richTextBox1.Document = (FlowDocument)System.Windows.Markup.XamlReader.Load(xr);

 

第二種方法：將二進制數據賦值給richTextBox

System.IO.Stream ss = new System.IO.MemoryStream(data);
FlowDocument doc = System.Windows.Markup.XamlReader.Load(ss) as FlowDocument;
ss.Close();
richTextBox1.Document = doc;

 

清空RichTextBox的方法

System.Windows.Documents.FlowDocument doc = richTextBox.Document;
doc.Blocks.Clear();

 

如何將一個String類型的字符串賦值給richTextBox

myRTB.Document = new FlowDocument(new Paragraph(new Run(myString)));
FlowDocument doc = new FlowDocument();
Paragraph p = new Paragraph(); // Paragraph 相似於 html 的 P 標籤
Run r = new Run(myString); // Run 是一個 Inline 的標籤
p.Inlines.Add(r);
doc.Blocks.Add(p);
myRTB.Document = doc;

 

如何將richTextBox中的內容以rtf的格式徹底取出

string rtf = string.Empty;
TextRange textRange = new TextRange(richTextBox.Document.ContentStart, richTextBox.Document.ContentEnd);
using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
{
textRange.Save(ms, System.Windows.DataFormats.Rtf);
ms.Seek(0, System.IO.SeekOrigin.Begin);
System.IO.StreamReader sr = new System.IO.StreamReader(ms);
rtf = sr.ReadToEnd();
}

 

操做RichTextBox
複製 

ToolBarCopy.Command = System.Windows.Input.ApplicationCommands.Copy;

剪切 

toolBarCut.Command = System.Windows.Input.ApplicationCommands.Cut;

粘貼 

ToolBarPaste.Command = System.Windows.Input.ApplicationCommands.Paste;

撤銷 

ToolBarUndo.Command = System.Windows.Input.ApplicationCommands.Undo;

復原 

ToolBarRedo.Command = System.Windows.Input.ApplicationCommands.Redo;

文字居中 

toolBarContentCenter.Command = System.Windows.Documents.EditingCommands.AlignCenter;

文字居右 

toolBarContentRight.Command = System.Windows.Documents.EditingCommands.AlignRight;

文字居左 

toolBarContentLeft.Command = System.Windows.Documents.EditingCommands.AlignLeft;

有序排列 

ToolBarNumbering.Command = System.Windows.Documents.EditingCommands.ToggleNumbering;

無序排列 

ToolBarBullets.Command = System.Windows.Documents.EditingCommands.ToggleBullets;

字體變大

int fontSize = Convert.ToInt32(richTextBox.Selection.GetPropertyValue(TextElement.FontSizeProperty));
fontSize++;
richTextBox.Selection.ApplyPropertyValue(TextElement.FontSizeProperty, fontSize.ToString());
