如何设置winform中label的Text的行间距和字符间距

[emanlee]

如果label中有几行文字，如何设置行行之间的间距呢？

这个问题我曾在
http://community.csdn.net/Expert/topic/4749/4749698.xml?temp=5.942935E-02
中问过，也参看过

不过问题没有得到解决，因此另开贴寻求各位的帮助。谢谢！

你自己去写一个com，来替代label。至于多行间距，你可以用Graphics.DrawString来实现。

做一个控件，里面右几个label组成，怎么控制都好了。我就试过这样的

如果只是显示文字(没有任何事件),建议用Graphics.DrawString直接绘到窗体上.

费了一番周折终于解决了，以下若有不当之处敬请各位指教，谢谢！
