我有一个WPF .NET 4的C#的RichTextBox
,我想在与其他字符的文本框替换某些字符,这是发生在的KeyUp
事件。
I have a WPF .NET 4 C# RichTextBox
and I'm wanting to replace certain characters within that text box with other characters, this is to happen on the KeyUp
event.
我试图做到的,是全词,例如替换首字母缩写词: PC =个人电脑 SC =星际争霸 等等...
What I'm trying to achieve is replace acronyms with full words, e.g.: pc = personal computer sc = starcraft etc...
我已经看了一些类似的主题,但任何事情我发现一直没有成功我的方案。
I've looked a few similar threads, but anything I've found hasn't been successful in my scenario.
最后,我希望能够与缩略语表做到这一点。不过,我在使用,甚至取代单一的首字母缩写的问题,任何人都可以帮忙吗?
Ultimately, I'd like to be able to do this with a list of acronyms. However, I'm having issues with even replacing a single acronym, can anyone help?
推荐答案
由于 System.Windows.Controls.RichTextBox
不具有属性文字
来检测它的价值,你可能会使用其检测值以下
Because System.Windows.Controls.RichTextBox
does not have a property for Text
to detect its value, you may detect its value using the following
string _Text = new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd).Text;
然后,您可以更改 _text
,并使用以下发布新的字符串
Then, you may change _Text
and post the new string using the following
_Text = _Text.Replace("pc", "Personal Computer");
if (_Text != new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd).Text)
{
new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd).Text = _Text;
}
所以,它看起来会像这样
So, it'd look like this
string _Text = new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd).Text;
_Text = _Text.Replace("pc", "Personal Computer"); // Replace pc with Personal Computer
if (_Text != new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd).Text)
{
new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd).Text = _Text; // Change the current text to _Text
}
备注:除了使用 Text.Replace(下称电脑,个人电脑);
,你可以声明一个列表与LT;字符串>
中保存字符,而其替代品
Remark: Instead of using Text.Replace("pc", "Personal Computer");
you may declare a List<String>
in which you save the characters and its replacements
示例:
List<string> _List = new List<string>();
private void richTextBox1_TextChanged(object sender, TextChangedEventArgs e)
{
string _Text = new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd).Text;
for (int count = 0; count < _List.Count; count++)
{
string[] _Split = _List[count].Split(','); //Separate each string in _List[count] based on its index
_Text = _Text.Replace(_Split[0], _Split[1]); //Replace the first index with the second index
}
if (_Text != new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd).Text)
{
new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd).Text = _Text;
}
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
// The comma will be used to separate multiple items
_List.Add("pc,Personal Computer");
_List.Add("sc,Star Craft");
}
谢谢, 我希望对您有所帮助:)
