MinimizeName在C#中的实现代码(解决了我那个GDI+的问题)
代码如下:
//测试用的文字是:中华人民1共和国万岁!!!我爱北23京4天安门!!!
//字体:宋体,小三
int MagicNumber = 5;
protected override void OnPaint(PaintEventArgs e){
Graphics g = e.Graphics;
g.DrawString(MeasureString(g,Text,Font,this.ClientSize.Width-MagicNumber),Font,SystemBrushes.WindowText,0,0);
base.OnPaint (e);
}
private string MeasureString(Graphics g,string text,Font font,int maxwidth){
SizeF sf = g.MeasureString(text,font);
if(sf.Width<maxwidth)return text;
int len = text.Length;
string s = "";
StringBuilder sb = new StringBuilder(64);
for(int i=len-1;i>=0;i--){
sb.Remove(0,sb.Length);
sb.Append(text.Substring(0,i));
sb.Append("...");
s = sb.ToString();
sf = g.MeasureString(s,font);
if(sf.Width<=maxwidth)break;
}
return s;
}
private void Form1_Resize(object sender, System.EventArgs e){
Invalidate();
}
这是效果1:
这是效果2:
这是效果3:
