如何获取文本基线和标签水平边框之间的距离？(How to get the distance between the baseline of text and the horizontal border of a label?)

我想获得文本基线和C＃中标签底边之间的确切距离。 我想要这个因为我想在文本下画一条线（不想使用带下划线的字体，因为它非常紧密/接近文本）。

这是我的尝试：

//This is placed in the custom label class int dy = (int)((ClientRectangle.Height - Font.GetHeight())/2);

但这并不准确，dy返回约3，绘制到标签的线距离文本的基线太远。

I want to get the exact distance between the baseline of the text and the bottom border of a label in C#. I want this because I want to draw a line under the text (don't want to use underlined font, because it's so tight/close to the text).

Here is my try:

//This is placed in the custom label class int dy = (int)((ClientRectangle.Height - Font.GetHeight())/2);

But it's not exact, the dy returns about 3 and the line drawn to the label is too far from the baseline of the text.

最满意答案

要获取标签的文本基线，假设您在自定义标签类中，在绘图处理程序中。

Font myFont = this.Font; FontFamily ff = myFont.FontFamily; float lineSpace = ff.GetLineSpacing(myFont.Style); float ascent = ff.GetCellAscent(myFont.Style); float baseline = myFont.GetHeight(e.Graphics) * ascent / lineSpace;

信用就在这里 。

To get text baseline for a label, assuming you are inside the custom label class, in the drawing handler.

Font myFont = this.Font; FontFamily ff = myFont.FontFamily; float lineSpace = ff.GetLineSpacing(myFont.Style); float ascent = ff.GetCellAscent(myFont.Style); float baseline = myFont.GetHeight(e.Graphics) * ascent / lineSpace;

Credit goes here.
