关于重绘标签控件 [英] About redraw label control

问题描述

我想实现标签控制文本显示前面的四个字符都是白色的，后一个字是全红色的。 
以下是我的代码：
 <   pre     lang   =  c＃ >  
 //我用过：作为分隔符
 public Rectangle DeflateRect（Rectangle rect，Padding padding）
 {
 rect.X + = padding.Left; 
 rect.Y + = padding.Top; 
 rect.Width  -  = padding.Horizo​​ntal; 
 rect.Height  -  = padding.Vertical; 
返回rect; 
} 
 
 
 protected override void OnPaint（PaintEventArgs e）
 {
 base.OnPaint（e）; 
 
 
矩形r = DeflateRect（base.ClientRectangle，base.Padding）; 
 
 if（this.Text.Length> 0）
 {
 string [] str = this.Text.Split（new char [] {'：'}）; 
 if（str.Length> 0）
 {
 TextRenderer.DrawText（e.Graphics，
 this.Text.Substring（0，str [0] .Length + 1 ），this.Font，r，Color.White，base.BackColor，TextFormatFlags.Left）; 
 
 
 TextRenderer.DrawText（e.Graphics，
 this.Text.Substring（str [0] .Length + 1，str [1] .Length），this.Font ，r，Color.Red，base.BackColor，TextFormatFlags.Right）; 
} 
} 
} 
 
 
 
 <   / pre  >  
 
 <   pre     lang   =  vb > 然而，我遇到了以下问题：
当& quot; \ naaaaaaaaaaaaaaaaaaaa \ nbbbbbbbbbbbbbbbbbb \ nccccccccc& quot;当控制字生成器和原始偏移量时，将显示多个换行符，它看起来像控制字上显示的两种颜色<   / pre  >

I want to achieve label control text display in front of four characters are white, the latter word is all red.
The following is my code:
<pre lang="c#">
    //I have used: as a separator
    public Rectangle DeflateRect(Rectangle rect, Padding padding)
        {
            rect.X += padding.Left;
            rect.Y += padding.Top;
            rect.Width -= padding.Horizontal;
            rect.Height -= padding.Vertical;
            return rect;
        }


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


            Rectangle r = DeflateRect(base.ClientRectangle, base.Padding);

            if (this.Text.Length > 0)
            {
                string[] str = this.Text.Split(new char[] { ':' });
                if (str.Length > 0)
                {
                    TextRenderer.DrawText(e.Graphics,
                       this.Text.Substring(0, str[0].Length + 1), this.Font, r, Color.White, base.BackColor, TextFormatFlags.Left);


                    TextRenderer.DrawText(e.Graphics,
                     this.Text.Substring(str[0].Length + 1, str[1].Length), this.Font, r, Color.Red, base.BackColor, TextFormatFlags.Right);
                }
            }
        }



</pre>

<pre lang="vb">However, I encounter the following problems:
           When &quot;\ naaaaaaaaaaaaaaaaaaaaa \ nbbbbbbbbbbbbbbbbbbb \ nccccccccc&quot; multiple newline character will be displayed when the control word generator and the original offset, it looks like two kinds of color displayed on the control word</pre>
