C#中怎样得到一个字符串的宽度和高度呢？有没有函数阿？

[「已注销」]

如题，有没函数可以直接的倒字符串的宽度和高度呢？谢谢

[q107770540]

string s="aaaa";
int i=s.Length; //4

字符串的高度宽度要在某个GDI/GDI+环境下才有意义，比如当前窗体的：

using (Graphics g = this.CreateGraphics())
{
    SizeF string_size = g.MeasureString("字符串", this.Font);
}

gdi下用

[DllImport("gdi32.dll", EntryPoint="GetTextMetrics")]
public static extern int GetTextMetrics (
	int hdc,
	ref TEXTMETRIC lpMetrics
);

MeasureString

像素
MeasureString 和MeasureCharacterRanges
string s="";
float w=0;
float h=0;
Graphics g=Graphics.FromHwnd(this.Handle);
Font myf=new Font( "宋体 ",15);
StringFormat sf=new StringFormat(StringFormat.GenericTypographic);
SizeF size=g.MeasureString(s,myf,1000,sf);
