我找不到该功能.基本上，我有一个多行文本框，当我执行搜索时，我会突出显示结果.但是，如果结果不在视图范围内，我将不得不手动向下滚动，直到找到突出显示的结果，这超出了查找"功能的目的.

I'm unable to find that function. Basically I have a multiline text box and when I perform a search, I highlight the result. But if the result is not within view, I would have to manually scroll down until I find the highlighted result, which beats the purpose of the "Find" functionality.

我不想使用RichTextBox，因为我遇到了一些性能问题.

I don't want to use RichTextBox because I've encountered some performance issues with it.

推荐答案

您可以使用 GetLineIndexFromCharacterIndex 与 ScrollToLine :

You could use GetLineIndexFromCharacterIndex in combination with ScrollToLine:

var selectionStart = x; var selectionLength = y; textBox.Select(selectionStart, selectionLength); textBox.ScrollToLine(textBox.GetLineIndexFromCharacterIndex(textBox.SelectionStart));
