How can I convert a string length to a pixel unit?
提问by ScottG
I have a string like this:
我有一个这样的字符串：
string s = "This is my string";
I am creating a Telerik report and I need to define a textboxthat is the width of my string. However the size property needs to be set to a Unit (Pixel, Point, Inch, etc). How can I convert my string length into, say a Pixel so I can set the width?
我正在创建一个 Telerik 报告，我需要定义一个textbox字符串的宽度。但是 size 属性需要设置为一个单位（像素、点、英寸等）。如何将我的字符串长度转换为像素，以便我可以设置宽度？
EDIT:I have tried getting a reference to the graphics object, but this is done in a class that inherits from Telerik.Reporting.Report.
编辑：我尝试获取对图形对象的引用，但这是在继承自Telerik.Reporting.Report.

Without using of a control or form:
不使用控件或表单：
using (System.Drawing.Graphics graphics = System.Drawing.Graphics.FromImage(new Bitmap(1, 1)))
{
SizeF size = graphics.MeasureString("Hello there", new Font("Segoe UI", 11, FontStyle.Regular, GraphicsUnit.Point));
}
Or in VB.Net:
或者在 VB.Net 中：
Using graphics As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(New Bitmap(1, 1))
Dim size As SizeF = graphics.MeasureString("Hello there", New Font("Segoe UI", 11, FontStyle.Regular, GraphicsUnit.Point))
End Using

You can create an instance of a graphics object an use the MeasureString()method. But you will need to pass it the font name, font size, and other info.
您可以创建图形对象的实例并使用该MeasureString()方法。但是您需要将字体名称、字体大小和其他信息传递给它。

Depends on the font, too. String length isn't sufficient.
也要看字体。字符串长度不够。

Size textSize = TextRenderer.MeasureText("How long am I?", font);

In this case, I usually use a dirty, but simple way:
在这种情况下，我通常使用一种肮脏但简单的方法：
- I add an invisible
Labelthat itsAutoSizeproperty istrue-dirty work-. - When I want to have the
Widthfor a specific string, I set it to theLabel.Text. - The
Widthof theLabelwill give me the correct value.
- 我添加了一个无形的
Label，它的AutoSize属性是true-肮脏的工作- 。 - 当我想要
Width一个特定字符串时，我将它设置为Label.Text. - 该
Width的Label会给我正确的值。
