在标签路径显示 [英] Path Display in Label

问题描述

是否有任何自动方法在.NET微调路径字符串？

例如：

  C：\ Documents和Settings \尼克\我的文档\测试\演示数据\演示data.emx
 

变为

  C：\文件... \演示data.emx
 

这将是特别凉爽，如果这被内置到标签类，我似乎记得这是 - ！不容觉得它虽然

解决方案

使用 TextRenderer.DrawText 是 TextFormatFlags.PathEllipsis 标志

 无效label_Paint（对象发件人，PaintEventArgs的E）
{
  标签标签=（标签）发送;
  TextRenderer.DrawText（e.Graphics，label.Text，label.Font，label.ClientRectangle，label.ForeColor，TextFormatFlags.PathEllipsis）;
}
 

  

您code为95％存在。唯一   问题是，修整文本是   绘制在其上是文本的顶部   已在标签上。

是的，谢谢，我意识到了这一点。我的目的只是为了演示如何使用 DrawText的方法。我不知道你是否要手动创建活动为每个标签或只覆盖继承的标签的OnPaint（）方法。感谢您的分享，虽然最终的解决方案。

Are there any automatic methods for trimming a path string in .NET?

For example:

C:\Documents and Settings\nick\My Documents\Tests\demo data\demo data.emx

becomes

C:\Documents...\demo data.emx

It would be particularly cool if this were built into the Label class, and I seem to recall it is--can't find it though!

解决方案

Use TextRenderer.DrawText with TextFormatFlags.PathEllipsis flag

void label_Paint(object sender, PaintEventArgs e)
{
  Label label = (Label)sender;
  TextRenderer.DrawText(e.Graphics, label.Text, label.Font, label.ClientRectangle, label.ForeColor, TextFormatFlags.PathEllipsis);
}

Your code is 95% there. The only problem is that the trimmed text is drawn on top of the text which is already on the label.

Yes thanks, I was aware of that. My intention was only to demonstrate use of DrawText method. I didn't know whether you want to manually create event for each label or just override OnPaint() method in inherited label. Thanks for sharing your final solution though.
