如何更改按钮第二行文字中的字体大小和颜色?

最佳答案 使用.Text属性是不可能的……

…但您可以创建一个动态位图来代替Text,允许您根据需要对其进行格式化:

        Button button = new Button();
        button.Name = "btn" + idDanych;
        button.Width = 100;
        button.Height = 100;
        button.Location = new Point(0, 0);

        button.Text = "";
        Bitmap bmp = new Bitmap(button.ClientRectangle.Width, button.ClientRectangle.Height);
        using (Graphics G = Graphics.FromImage(bmp))
        {
            G.Clear(button.BackColor);

            string line1 = "( " + Wieszak + " ) " + Haczyk;
            string line2 = KodEAN;

            StringFormat SF = new StringFormat();
            SF.Alignment = StringAlignment.Center;
            SF.LineAlignment = StringAlignment.Near;
            using (Font arial = new Font("Arial", 12))
            {
                Rectangle RC = button.ClientRectangle;
                RC.Inflate(-5, -5);
                G.DrawString(line1, arial, Brushes.Black, RC, SF);
            }

            using (Font courier = new Font("MS Courier", 24))
            {
                SF.LineAlignment = StringAlignment.Center;
                G.DrawString(line2, courier, Brushes.Red, button1.ClientRectangle, SF);
            }
        }
        button.Image = bmp;
        button.ImageAlign = ContentAlignment.MiddleCenter;

        this.Controls.Add(button);

您必须找出字体大小,StringFormat布局和/或定位的最佳组合,以使其看起来符合要求.还有其他DrawString()重载以不同的方式呈现文本.

但请注意,控件突出显示的方式会有所不同.在我的系统上,当鼠标进入时,标准按钮的整个区域会突出显示.使用此方法,只有边框会突出显示,因为按钮的整个中间是静态图像.
