问题 We are creating PDF documents on the fly from the database using PDFsharp. I need to know the best way to calculate the height of the text area based on the font used and the available width. I need to know the height so I can process page breaks when required. 回答1: In .NET you can call Graphics.MeasureString to find out how large the drawn text is going to be. Right, but when using PDFsharp you call XGraphics.MeasureString. 回答2: The PdfSharp.Drawing.XGraphics object has a MeasureString

问题 I have a string called Message. Message = "Hello, welcome!\nThis is some text that should be centered!" Yeah, it's just a test statement... And I'm trying to centre it for a default Terminal window, i.e. of 80 width, with this statement: print('{:^80}'.format(Message)) Which prints: Hello, welcome! This is some text that should be centered! I'm expecting something like: Hello, welcome! This is some text that should be centered! Any suggestions? 回答1: You need to centre each line separately: '

问题 This question already has answers here : Is there an easy way to create ordinals in C#? (20 answers) Closed 5 years ago . I am wondering if there is a method or format string I'm missing in .NET to convert the following: 1 to 1st 2 to 2nd 3 to 3rd 4 to 4th 11 to 11th 101 to 101st 111 to 111th This link has a bad example of the basic principle involved in writing your own function, but I am more curious if there is an inbuilt capacity I'm missing.

问题 I'm trying not to use the ',' char as a thousand separator when displaying a string, but to use a space instead. I guess I need to define a custom culture, but I don't seem to get it right. Any pointers? eg: display 1000000 as 1 000 000 instead of 1,000,000 (no, String.Replace() is not the solution I'd like to use :P) 回答1: I suggest you find a NumberFormatInfo which most closely matches what you want (i.e. it's right apart from the thousands separator), call Clone() on it and then set the

问题 I would like my WPF application to display all percentages without % sign. For example 20% would be displayed as "20" but i still want to use the standard formatting for percentages (so i get the benefit of string formatter to multiply it by 100 for me) in other words, how do i get string.Format("0.00%", 0.2) to output "20" but not "20%"? Is it possible to globally define PercentSymbol as empty string for the entire application? In particular i am using ContentStringFormat in my WPF

问题 How can I Lock/Unlock a cell(A1) based on value(yes/no) in another cell(A2) using conditional formatting? 回答1: There's lots of resources online showing how to do this.
