C#richtextbox implementation (copy, cut, paste, select All)

Ext: http://www.cnblogs.com/JuneZhang/archive/2011/05/20/2051973.html

There are two main ways to implement this menu:

First: implemented by sending keystrokes to the application.

First focus to the currently active RichTextBox, and then by sending the keystroke command to implement the Operation function

Richtextbox1.focus ();

Sendkeys.send ("^a")/Select All

Sendkeys.send ("^c");/copy

Sendkeys.send ("^x");//Cut

Sendkeys.send ("^v");//paste

The second type: directly manipulate the Clipboard implementation by command

Copy

Clipboard.setdata (DATAFORMATS.RTF, RICHTEXTBOX1.SELECTEDRTF)//Copy RTF data to clipboard

Shear

Clipboard.setdata (DATAFORMATS.RTF, RICHTEXTBOX1.SELECTEDRTF)//Copy RTF data to clipboard

Richtextbox1.selectedrtf= "" "" ", or the current selection of RTF content to clear out, the current implementation of the cut function.

Paste

Richtextbox1.paste ()//paste the data on the Clipboard to the target RichTextBox

Select All (there are two ways to select all of them)

Richtextbox1.focus ()//sets the first focus to the current active RichTextBox, which is important, otherwise it will not execute correctly

The other is through the select (int start,int length) method to implement

Richtextbox1.select (0, RichTextBox1.Rtf.Length);//richtextbox1.rtf.length represents the length of text in RichTextBox

One is to directly adopt the SelectAll () method provided in the NET Framework to select all

Richtextbox1.selectall ();
