c# - C#应用程序的标记栏？

我可以在我的应用程序中使用C#应用程序的标记栏组件吗？作为标记栏，我的意思是像ReSharper这样的东西添加到了Visual Studio中:

另一个类似的示例(左侧的栏):

编辑:我发现java http://www.sideofsoftware.com/marker_bar/doc/sos/marker/JMarkerBar.html的非免费组件究竟是什么，我想做什么。它不适合我，但也许可以帮助某人。

最佳答案

在WPF中，该条有点像ListBox，只是以不同的方式为每行文本显示1像素高的行。线的状态将影响线的颜色，选择线将引发文本框可以响应的SelectionChanged事件。

如果您要我展示原型(prototype)，请告诉我。

开始。您可以单击/选择栏中的一行，文本框将滚动到该行。

仍要添加:

如果栏的行数太大，该怎么办？

以其他方式显示栏中的当前行吗？

使栏中的所选行与文本框中的插入符号保持同步。

这些可以解决，但在很大程度上取决于您想要什么。这应该可以帮助您入门。
