C＃中的图形（.NET）

Question

I use this code for drawing text in a panel:

Graphics g = panel1.CreateGraphics();
g.DrawString(...);

So I want to know what size the input text will be when rendered in the panel.

Answer 1

Use g.MeasureString() to get the width of a string in the grapic context.

// Set up string.
string measureString = "Measure String";
Font stringFont = new Font("Arial", 16);

// Measure string.
SizeF stringSize = new SizeF();
stringSize = e.Graphics.MeasureString(measureString, stringFont);

Answer 2

您还可以使用TextRenderer.MeasureText ，它有时比MeasureString更容易使用。
