dotnet:如何获得字体的平均字符宽度？

Question

Windows窗体:

因为System.Drawing有一种方法可以获得字体高度.

Font font = new Font("Arial", 10 , FontStyle.Regular);
float fontHeight = font.GetHeight(); 

但是,如何获得平均字符宽度等其他文本指标？

Answer 1

使用 Graphics.MeasureString 方法

private void MeasureStringMin(PaintEventArgs e)
{

    // 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);

    // Draw rectangle representing size of string.
    e.Graphics.DrawRectangle(new Pen(Color.Red, 1), 0.0F, 0.0F, stringSize.Width, stringSize.Height);

    // Draw string to screen.
    e.Graphics.DrawString(measureString, stringFont, Brushes.Black, new PointF(0, 0));
}
