如何以编程方式衡量ASP.NET串像素宽度？ [英] How to programmatically measure string pixel width in ASP.NET?

问题描述

你如何得到一个字符串的大小？在Windows窗体很容易，我只是使用图形对象，然后MeasureString功能。在ASP.NET我不知道如何做到这一点。

How do you get the size of a string? In Windows Forms it's easy, I just use graphics object and then MeasureString function. In ASP.NET I'm not sure how to do this.

推荐答案

和汤姆一样Gullen在说什么。你可以创建一个位图和messure字符串。我有这个code我用它来查找像素宽/长。只是改变了字体和大小。

Like Tom Gullen is saying. You can just create a bitmap and messure the string. I have this code I use to find the width/length in pixel. Just change the font and size.

// Bitmap class namespace:
using System.Drawing;

...

private float GetWidthOfString(string str)
{
    Bitmap objBitmap = default(Bitmap);
    Graphics objGraphics = default(Graphics);

    objBitmap = new Bitmap(500, 200);
    objGraphics = Graphics.FromImage(objBitmap);

    SizeF stringSize = objGraphics.MeasureString(str, new Font("Arial", 12));

    objBitmap.Dispose();
    objGraphics.Dispose();
    return stringSize.Width;
}

只是想表明一个例子。

Just wanted to show an example.
