Windows mobile 紧凑框架：使用椭圆绘制多行字符串

我正在为Windows Mobile应用程序创建从ListView继承的所有者绘制控件。我正在使用

Graphics.DrawString

写出一个两行文本字符串（使用.NET CF 3.5）。问题是有些项目有特别长的文本，不适合两行。谷歌已经找到了使用

MeasureString

和手动截断字符串的方法，但这只适用于单行字符串。有没有办法在这里得到省略号，或者我必须接受剪裁文本或重新设计以仅使用一行？（两者都不是交易破坏者，但省略号肯定很好。）

是的，您可以让省略号显示出来，但您必须进行一些p/调用（有什么新功能？）：

我担心P/Invoke会牵涉其中。但答案很好！

public static void DrawText(Graphics gfx, string text, Font font, Color color, int x, int y, int width, int height)
{
 IntPtr hdcTemp = IntPtr.Zero;
 IntPtr oldFont = IntPtr.Zero;
 IntPtr currentFont = IntPtr.Zero;

 try
 {
  hdcTemp = gfx.GetHdc();
  if (hdcTemp != IntPtr.Zero)
  {
   currentFont = font.ToHfont();
   oldFont = NativeMethods.SelectObject(hdcTemp, currentFont);

   NativeMethods.RECT rect = new NativeMethods.RECT();
   rect.left = x;
   rect.top = y;
   rect.right = x + width;
   rect.bottom = y + height;

   int colorRef = color.R | (color.G << 8) | (color.B << 16);
   NativeMethods.SetTextColor(hdcTemp, colorRef);

   NativeMethods.DrawText(hdcTemp, text, text.Length, ref rect, NativeMethods.DT_END_ELLIPSIS | NativeMethods.DT_NOPREFIX);
  }
 }
 finally
 {
  if (oldFont != IntPtr.Zero)
  {
   NativeMethods.SelectObject(hdcTemp, oldFont);
  }

  if (hdcTemp != IntPtr.Zero)
  {
   gfx.ReleaseHdc(hdcTemp);
  }

  if (currentFont != IntPtr.Zero)
  {
   NativeMethods.DeleteObject(currentFont);
  }
 }
}

internal const int DT_END_ELLIPSIS = 32768;
internal const int DT_NOPREFIX = 2048;
