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
