如何在WPF或WinForms中呈现公式

Question

Update 2018 TL;DR; LaTEX for WPF https://github.com/ForNeVeR/wpf-math

Original question I need to have a way to draw a mathematical formula in Windows Forms or WPF. Some "FormulaTextBox" control would be exactly what I need.

I'm not asking about full implementation of LaTEX, but at least something beyond RichTextBox possibilities, with division lines, square roots, etc.

Answer 1

Here's a list of options, pulled from several webpages online, as well as a few similar questions on SO

• WPF-Math , a WPF library for rendering math-related TeX markup.
• gNumerator is a WinForms control that renders MathML . It is native C#, but appears to be quite old.
• Math Expressions , a commercial WinForms control for displaying and editing math equations. Note: Not free
• There's an unofficial port of JMathTex to a C# WPF control
• The Windows version of the LaTex editor Lyx uses a native library called MikTex you could take a look at. I saw mention somewhere that the tex4ht package renders math equations to images
• MimeTex / MathTex , as you already mentioned
• You could also use a WebBrowser control, and just locally include one of many javascript libraries for rendering LaTex.
• You could pawn off the work onto Microsoft Word ( Example - requires users to have MS Word installed! )

也许您可以使用Wolfram Alpha API检索图像。

Answer 3

If you want something beyond a RichTextBox abilities to render pie, divisions and sqr roots and etc, you could just use WebBrowserControl(s) as textbox's. Then to render formula's you could leverage techniques shown in this webpage, save it to your desktop and open the html file:

Obviously you'll need a special syntax (or special calculator buttons) to enter the formula's and I'm guessing from looking at the customisations.js file driving that webpage that you could make your own list of operators and functions too.

Answer 4

Here's what I'd do if none of the .NET specific solutions work for you:

It's a bit hacky, but it'll work and your users won't know the difference. Download the Mathjax library. When your user enters in the equation, you could convert the equation to LaTex or MathML. You would then take the LaTex or MathML and generate an HTML file that references Mathjax and display the file in your tiny WebBrowser window (valid for both WinForms and WPF). This shouldn't require an internet connection.

Like I said, your users won't be any the wiser.
