我如何获得文字大小？

Question

我想为文本创建一个Rectangle.但我不知道字符串的大小.现在我得到如下大小(对于带大写的字符串无效):

var textSize = e.Graphics.MeasureString(text, e.Appearance.Font);

但是如果我的字符串是大写的,这个函数将返回错误的值.

如果字符串是大写的,如何获取字符串的大小？

MeasureString适合我.找到以下代码.

public partial class Form1 : Form
        {
        public Form1()
            {
            InitializeComponent();
            }

        private void Form1_Load(object sender, EventArgs e)
            {

            }
        protected override void OnPaint(PaintEventArgs e)
            {
            base.OnPaint(e);
            MeasureStringMin(e);
            }
        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));
            }
        }
