C# 应用程序是否有我可以在我的应用程序中使用的标记栏组件？作为标记栏，我的意思是 ReSharper 添加到 Visual Studio:

另一个类似的例子(左边的栏):

编辑:我发现 java 的非自由组件 http://www.sideofsoftware.com/marker_bar/doc/sos/marker/JMarkerBar.html什么正是我想做的。它不适合我，但也许对某人有帮助。

最佳答案

在 WPF 中，栏有点像列表框，只是为每行文本显示 1 像素高的行的方式不同。线条的状态会影响线条的颜色，选择线条会引发文本框可以响应的 SelectionChanged 事件。

如果您想让我展示原型(prototype)，请告诉我。

来了。您可以单击/选择栏中的一行，文本框将滚动到该行。

还有待补充:

1. 条形图的行数过多怎么办？

2. 显示栏中当前行的不同方式？

3. 使栏中的选定行与文本框中的插入符号保持同步。

4. ...

这些都可以解决，但很大程度上取决于你想要什么。这应该可以帮助您入门。
