我有RichTextBox,就像“console”。在'cmd'中我显示来自SSH连接的数据,我还允许在'cmd'RichTextBox中写入内容。
public void ConnectTTY()
{
NewTerminal = new TTY(HostBox.Text, "", LoginBox.Text, PasswordBox.Text);
Thread.Sleep(1000);
ReadStreamAsync(NewTerminal.reader, cmd);
// cmd is my RichTextBox . At first I am filling it with data from server
// and in next step I am allowing user to write some command
cmd.Focus();
cmd.CaretPosition = cmd.Document.ContentEnd;
cmd.ScrollToEnd();
LastChar = cmd.Document.ContentEnd ;
}
在最后几行中,我使用TextPointer“LastChar”获取最后添加内容的位置,因为我想知道用户将在RichTextBox中写入什么内容。
On“Enter”事件我使用ReWriteStream获取最后一个文本并通过SSH发送。
public void ReWriteStream()
{
string myText = new TextRange(LastChar, cmd.Document.ContentEnd).Text ;
MessageBox.Show("Tekst: " + myText.ToString() );
if ( myText.Length != 0 )
{
WriteStreamAsync(myText, NewTerminal.writer, NewTerminal.stream);
ReadStreamAsync(NewTerminal.reader, cmd);
//WriteStream(myText, NewTerminal.writer, NewTerminal.stream);
//Thread.Sleep(1000);
//ReadStream(NewTerminal.reader, cmd);
}
cmd.Focus();
}
但每次,我的变量myText都是空的。
string myText = new TextRange(LastChar, cmd.Document.ContentEnd).Text ;
如何获取在LastChar位置后写入RichTextBox的任何文本?
感谢您的帮助, 最好的祝福, Wiktor的
编辑:我已将字符串放入richtextbox来分析插入位置:
public void ConnectTTY()
{
NewTerminal = new TTY(HostBox.Text, "", LoginBox.Text, PasswordBox.Text);
Thread.Sleep(1000);
ReadStreamAsync(NewTerminal.reader, cmd);
cmd.Focus();
cmd.CaretPosition = cmd.Document.ContentEnd;
cmd.ScrollToEnd();
cmd.CaretPosition.InsertTextInRun("|1|");
// LastChar = cmd.CaretPosition.DocumentEnd;
}
在这里:
public void ReWriteStream()
{
string caret;
string myText;
LastChar = cmd.CaretPosition.DocumentEnd.GetInsertionPosition(LogicalDirection.Backward);
cmd.CaretPosition.InsertTextInRun("|2|");
myText = new TextRange(LastChar, cmd.CaretPosition.DocumentEnd).Text;
// myText = new TextRange(LastChar, cmd.Document.ContentEnd).Text;
MessageBox.Show("Text : " + myText.ToString() );
if ( myText.Length != 0 )
{
WriteStreamAsync(myText, NewTerminal.writer, NewTerminal.stream);
ReadStreamAsync(NewTerminal.reader, cmd);
//WriteStream(myText, NewTerminal.writer, NewTerminal.stream);
//Thread.Sleep(1000);
//ReadStream(NewTerminal.reader, cmd);
}
cmd.Focus();
}
我在cmd RichTextBox中得到了它应该是什么: “ 你有邮件。 -bash-3.2 $ | 1 | ls -l <strong> | 2 | “
答案 0 :(得分:1)
另一种方法是抓取最后一个插入位置,然后将其用于文本范围。
public void ReWriteStream()
{
var myText = new TextRange(rtb.CaretPosition.GetLineStartPosition(0), rtb.CaretPosition.GetLineStartPosition(1) ?? rtb.CaretPosition.DocumentEnd).Text;
...
}
