如何检测在C＃中的线串溢出？ [英] How to detect a string-overflow from a line in C#?
问题描述
我想知道如何换 - 在C＃中，当我在一条线上的在这个网址。不幸的是，我没有足够的声誉问OP直接有关的有一个具体的问题我有（最有可能的人处理这将无限期有）
I wanted to know how to word-wrap in C# when I came across a very good solution to my problem on word-wrapping text in a line in this URL. Unfortunately, I do not have enough reputations to ask the OP directly about one specific problem I am having(and most likely people dealing with this will be having indefinitely)
问题描述：
我可以自动换行一个字符串，如果它需要自动换行，此代码：
Problem Description:
I can word-wrap a string if it needs to be word-wrapped with this code:
Graphics PAddress = e.Graphics;
SizeF PAddressLength = PAddress.MeasureString("Residential Address: " + RAddressTextBox.Text, new Font(fontface, fontsize, FontStyle.Regular),700);
PAddress.DrawString("Residential Address: "+PAddressLength + RAddressTextBox.Text, new Font(fontface, fontsize, FontStyle.Regular), Brushes.Black, new RectangleF(new Point(pagemarginX, newline()),PAddressLength),StringFormat.GenericTypographic);
不过，我找不到地方接收触发每当字长从单一的溢出。行
However, I could not find the place to receive a trigger whenever the word-length overflows from a single line.
例如：
在 LINE-2的代码每当字长超过 700像素，它移动到下一行。它是通过跟随的RectangleF来换行。它是这样做的的自动的，这是一个问题，因为这使得它很难知道是否已经越过700像素或没有。
这是
for example:
In LINE-2 of that code, whenever the wordlength exceeds 700px, it moves to the next line. It does that by following the RectangleF to wordwrap. It is doing so automatically, which is a problem since that makes it difficult to know whether it has crossed 700px or not.
This is the format in which information is displayed whenever I tried to print PAddressLength:
{宽度= 633.1881，身高= 47.14897：其中，每当我试图打印的 PAddressLength 显示格式信息}
{Width=633.1881, Height=47.14897}
我在想，如果我可以从使用PAddressLength.Width，那么我可以部分解决这个问题提取宽度值。但是，我会需要计算如果剩余空间（即700像素 - 633.1881px）将容纳下一个字或不（如果有一个）
I am thinking that If I can extract the value of width from that using PAddressLength.Width ,then I can partially solve this problem. But with that, I will need to calculate if the remaining space(i.e 700px - 633.1881px ) will accommodate the next word or not(if there is one)
<强>打破问题：
- 我的已的知道如何自动换行当有一个字符串比使用 Graphics.MeasureString <指定更长/ A>如
- 但是，这^过程自动发生，所以我想知道的如何检测是否自动换行已发生（怎么可能行已经包裹着每条线为700像素宽度最大值）
- 我需要为知道有才能知道的次数来执行被包裹的行数行（）函数，我写的，这给相应的行间距在每次执行。
- I already know how to word-wrap when there is a string longer than what specify by using Graphics.MeasureString as given in this solution in another question.
- But that^ process happens automatically, so I want to know how to detect if the word-wrap has occured(and how may lines it has wrapped with each line being 700px width maximum)
- I need to know the number of lines that have been wrapped in order to know the number of times to execute newline() function that I wrote, which gives appropriate line spacing upon executing each time.
此外，的（奖金的问题;可能或maynot解决的）有一些方法来提取值的 633.1881 ，然后计算出下一个单词是否（700适合 - 633.1881）PX 空间或不？
ADDITIONALLY, (bonus question; may or maynot solve) Is there some way to extract the value 633.1881 and then calculate whether the next word fits in ( 700 - 633.1881 )px space or not?
推荐答案
有一个超载MeasureString返回在输出参数使用的行数：的 https://msdn.microsoft.com/en-us/library/957webty ％28V = vs.110％29.aspx
There is an overload to MeasureString that returns the number of lines used in an out parameter: https://msdn.microsoft.com/en-us/library/957webty%28v=vs.110%29.aspx
